Abstract:
We investigated vibrato performance of university student and high school string players. Forty violinists and cellists performed an eight-measure passage both with and without vibrato. Analyses indicated that the mean rate of vibrato was approximately 5.5 Hz, with no significant differences between instruments or performer experience level. The mean width of violin vibratos was larger than cello vibratos. Violinists' mean pitch levels were sharper than cellists' in both vibrato and nonvibrato performances. Analysis of intonation patterns within the duration of tones showed that performers were more stable when using vibrato. University players tended to become sharper during both vibrated and nonvibrated tones compared to the younger players. Pitch oscillations during vibrato were alternations both above and below conceived pitch, rather than oscillations only above or only below the conceived pitch.

Abstract:
The purpose of this study was to investigate the perceived pitch of string vibrato tones. The authors used recordings of acoustic instruments (cello and violin) to provide both vibrato stimulus tones and the nonvibrato tones that listeners adjusted to match the perceived pitch of the vibrato stimuli. We were interested especially in whether there were differences in pitch perception of vibrato tones between string performers ( n = 36) and music majors without string performance experience ( n = 36). Both groups of music major listeners perceived the pitch of vibrato tones very near the mean frequency of the vibrato for cello and violin tones. Although means were similar, string players exhibited significantly less deviation in tuning judgments than non-string players for both violin and cello tones. Results appear consistent with earlier perceptual research as well as performance research indicating that string performers vibrate both above and below the intended pitch.

Abstract:
The purpose of this study was to investigate possible influences of pitch register and dynamic level on vibrato rates and widths of university and high school violin and viola players. Analysis showed that pitch register significantly affected the vibrato rates and widths of the performers. Musicians vibrated 0.32 Hz faster and approximately 26 cents wider during high pitches than during low pitches. Dynamic level also significantly affected vibrato width. Performers increased vibrato width approximately 4 cents in the forte passages when compared to the piano passages. Furthermore, violinists demonstrated a tendency to vibrate slightly faster and wider than violists, and university performers varied their vibrato width to a greater extent between the piano and forte passages than did the high school performers. These results, along with further study, can contribute to the development of a systematic method for teaching vibrato.

Abstract:
The purpose of the present study was to investigate aspects of vibrato performance among high school and university string players. The main questions were to determine whether students consistently initiate vibrato in an upward or downward direction and whether players vibrate continuously when performing slurs. Forty high school and university violin and cello students played exercises that included tones performed with and without vibrato. We measured direction and magnitude of change when initiating vibrato, pitch levels of vibrated and nonvibrated tones, and duration of nonvibrato when performing slurs. Results showed that these high school and university players did not reveal consistent initial vibrato movements in either direction or magnitude. Performers vibrated both above and below conceived pitch, rather than only upward or only downward. All performers stopped vibrating during the transition between slurred notes. Mean duration of nonvibrato portions of university students (0.42 second) was slightly less than that of high school students (0.50 second). Implications of these results for string pedagogy are discussed. March 28, 2005 June 7, 2005

Abstract:
In this study, the researcher compared the ratings assigned to audio and videotaped vibrato performances of inexperienced and experienced violinists and violists. Thirty-three inexperienced players and 28 experienced players were videotaped white performing vibrato. A panel of experts rated the videotaped performances and then 6 months later rated the audio-only portion of the performances on five vibrato factors: width, speed, evenness, pitch stability, and overall sound. Experienced players' vibrato was rated higher for all factors, regardless of mode of presentation. In addition, results revealed significantly higher audiovisual ratings for pitch stability, evenness, and overall sound for inexperienced players, and for pitch stability for experienced players. Results suggest that string teachers need to occasionally listen to their students' vibrato without watching them since visual cues may inadvertently influence their evaluation of student achievement.

Full text
Abstract:
The purpose was to investigate muscle potential during the vibrato motion for successful, healthy violin/viola performers. Electromyography was used to analyze parameters of muscle potentials during performance of a standardized exercise. These parameters were (a) evidence of potentials, (b) patterns of potentials, and (c) timing relationships (24 muscles). This study also sought to replicate and expand performance data from previous studies. Procedures from three pilot studies were used to standardize collection of EMG data. Synchronized video recordings were used to determine vibrato speed and conduct motion analysis. EMG data processing prior to analysis included power spectrum analysis and rectification, low-pass filtering, and smoothing data. Motion analysis findings (£D) were 1.09 for the elbow joints and 3.25 for the wrist joints. which was an indication of range of motion, suggested much greater activity in muscles controlling wrist movement than those moving the elbow. The degree of muscle potential and control were generally related to distance from the vibrating hand. Forearm muscle groups (8) demonstrated the greatest evidence of potential (76.5%) and were 18.1% non-periodic. Muscles of the upper arm (7) were off 59.4% and 57.0% non-periodic. Upper arm muscles had greater individual differences. Muscles of the chest and back (9) were collectively inactive (89.1%) and non-periodic (73.3%). With timing relationships, the forearm muscles demonstrated consistent firing patterns. Inconsistent firing patterns were evident in the upper arm, and to a greater degree in the chest and back muscles. Based on evaluations of performer motion and muscle potentials, it was strongly implied that there are (a) distinct roles for various muscles during vibrato (control vs. stabilization/support), (b) significant differences in potential between variables of rest, playing position, and performing, (c) significant differences in potential between some fingers, and (d) no significant differences between violinists and violists. The vibrato motion appeared to be controlled primarily by forearm muscles.

Abstract:
Thesis (MMus (Music))--University of Stellenbosch, 2009
Violin vibrato is the action by which a violinist periodically changes the frequency of a sustained note by moving the finger on the string, rapidly backwards and forwards. If it is artistically applied, it adds life, character and warmth to an otherwise dull sounding note. Although it has been used since the sixteenth century, very little research has been done on the reason why humankind would experience such periodic fluctuations as an object of beauty in violin performance. In answering the question, this study explores a variety of angles of approach in order to understand the phenomenon in its full context. The history, development and geographical origin of the technique are firstly discussed in a diachronic fashion and provide the background for the subsequent synchronic research on the physical nature of violin sound and violin vibrato. The vibrato rates and widths of four virtuosi are measured and compared to highlight the differences and individuality which are argued to be a contributing factor to the perception of beauty of the technique. It is established in the final chapter that the brain is stimulated more by sounds with periodic changes than those that are presented in the steady-state which cast some light on why vibrato may be experienced as an appreciated addition to sound. The thesis aims to present a unique view on the possibilities of interdisciplinary research of the phenomenon of violin vibrato. It further aims to present the research findings in a concise, logical, and systematic manner that could be of interest to both musician and scientist.

This work proposes a methodology for the transfer of industrial and research domain methods toward arts and crafts domain. The virtual prototyping and mechanical characterization of materials are used for the stringed musical instruments making domain. The works is adressed to the guitar and violin making. This domain is historically driven by empricism and it is studied here using objective criteria. The main topic is the mechanical vibratory behaviour of musical instruments. Firstly, the mechanical behaviour of the material used (tonewood) is studied. A non-destructive methodology is proposed and applied on spruce and maple species. The reliability of the numerical models is studied by method usually used in industry and research, the verification and validation process. The models developed are used as a support for the study of complex phenomena in musical acoustics. Finally, the utilization of numerical method for a practical application in instrument making (decision support under uncertainties, geometric and material optimization) is proposed. The methodology for a transfer to art and crafts domain is discussed

Resumo: Atualmente, um importante aspecto da pesquisa em acústica musical consiste em relacionar propriedades físicas mensuráveis de um instrumento musical e a avaliação subjetiva de sua qualidade sonora ou tonal. Tem sido necessário, portanto, o desenvolvimento de métodos analíticos e numéricos para previsão do comportamento vibroacústico do instrumento, possibilitando a determinação de parâmetros objetivos que possam ser usados para controlar a sua qualidade tonal. Dessa forma, o presente trabalho realiza análises modais acústica, estrutural e vibroacústica (acoplamento entre fluido e estrutura), calculadas pelo método de elementos finitos (MEF), com o objetivo de determinar o comportamento dinâmico da caixa de ressonância da viola em termos de frequências naturais e as correspondentes formas dos modos. Primeiramente, é apresentado um modelo simplificado, que despreza as estruturas internas de reforço, mas adota as dimensões principais de uma viola real. Depois o mesmo modelo foi expandido, sendo acrescentados os reforços internos, porém com dimensões ainda aproximadas. Por fim, o terceiro modelo foi elaborado em relação às dimensões de uma viola real e seus respectivos reforços internos. Com isso, também foram realizados procedimentos experimentais a fim de verificar as capacidades e limitações do método computacional empregado. Finalmente, os resultados obtidos pelos métodos numéricos e experimentais são comparados e discutidos
Abstract: An important aspect of musical acoustics research is to identify the relationship of measurable physical properties of a musical instrument with the subjective evaluation of their sound quality or tone. Therefore, for musical instruments including resonance box, it is important to develop analytical or numerical methods to predict accurately its vibroacoustic behavior. These methods will enable the determination of key parameters that can be used to control the tone and sound quality. This work uses theoretical modal analysis with finite element method (FEM) to determine the dynamic behavior of a Brazilian guitar resonance box in terms of natural frequency and mode shapes. At first, is presented a simplified model that neglects the internal structures of reinforcement (struts, ribs, brackets, etc.), but adopts the main dimensions of a real Brazilian guitar. Then the same model was expanded with the addition of the internal reinforcements, but with approximate dimensions yet. Finally, the third model was designed regarding the dimensions of a real Brazilian guitar and their internal reinforcements. Experimental procedures were also performed to verify the capabilities and limitations of the computational method employed. The results obtained by numerical and experimental methods are compared and discussed

Abstract:
Ce travail porte sur le diagnostic des températures de vibration et de rotation des molécules dans les plasmas thermiques.

Ce mémoire comporte deux grandes parties : l'une concerne le calcul de spectres moléculaires et la deuxième partie est consacrée à la comparaison des spectres dans quatre cas expérimentaux différents.

Un code de calcul a été réalisé pour simuler des spectres d'espèces diatomiques. Ce code a été essentiellement appliqué aux radicaux C2, CN, à la molécule N2 et à l'ion N2+ avec comme paramètres variables les températures de vibration et de rotation. Cette partie commence par une description de la molécule diatomique et de ses propriétés.
Ensuite la méthode pour calculer les spectres est explicitée :
détermination des longueurs d'onde,
de leur intensité,
application d'une fonction d'appareil,
obtention du spectre final.
L'influence des températures de rotation et de vibration sur les intensités des raies est prise en compte ainsi que celle de la fonction d'appareil. Ces spectres sont calculés, pour une expérience donnée, de manière à déterminer ces deux paramètres par comparaison avec les spectres obtenus par la mesure.

Cette méthode a été utilisée sur quatre plasmas différents :
une flamme oxy-acétylénique,
un arc stabilisé dans une chambre de Maecker,
une torche à plasma ICP,
une décharge entre deux électrodes liquides.
Les températures de rotation et de vibration ont été déterminées par la comparaison de spectres. Ainsi des profils de températures ont pu être réalisés.

En annexe, les valeurs numériques nécessaires aux calculs de spectres sont répertoriées pour le système de Swan de C2, le système violet de CN, le second système positif de N2 et le premier système négatif de N2+.

Abstract:
AbstractIn this chapter the author discusses the difficulties of exploring the ethnography of events as they are happening, especially when they are violent, not least due to the lack of reliable information available and the complex process of interpreting transmissions of affect. The epistemological turn away from language—in which the focus on affect has emerged as a critique of post-structuralism’s inability to recognize the prediscursive forces that also shape the body—is, the author argues, imperative, as using the framework of affect theory and new materialism allows us to assess societies in flux as long as our material is grounded in empirical research. Examining the material consequences of recent uprisings in the Middle East and North Africa (MENA) region may provide a way of addressing key methodological issues in qualitative research in innovative and creative ways. In her ongoing project in Egypt, the author has identified the materialization of a certain clustering of affect by spending time with Cairenes during violent uprisings and her own lived experiences at such intense and uncertain moments, especially from the summer of 2013 and onwards. Starting with an inquiry into the material affective consequences—in particular changes to the vibration of sound but also encompassing other materialized experiences—this chapter reflects upon how the author’s attempt to formulate alternative methods of inquiry, anchored in affects and the body as a way of studying affective politics and the tangible emotions that resonate with and transform everyday engagements in a transitional country, provides useful tools for the study of change in the making.

Abstract:
Vibrato, its uses and misuses, has been a topic debated for centuries, with sources from all periods agreeing that it is an ornament to heighten expression that should not be over-used, which apparently it often was! This lesson traces the history of vibrato from the sixteenth century until today, using numerous quotes referring both to the violin and to other instruments. The continuous vibrato taught today as an essential aspect of sound production developed only in the twentieth century and was criticized at the time by prominent musicians. The lesson asks for what purpose and how much it was used in the Baroque period, by what technical means it was produced, and to what extent, if at all, it altered the pitch of a note. Two exercises seek to reproduce vibrato techniques as described at the start of the seventeenth and eighteenth centuries and another investigates how playing chinless affects vibrato.

Abstract:
One essential element of musical expression is the living sound, capable of holding the constant attention of the audience. This lesson traces that ubiquitous concept from Caccini’s “swelling and abating of the voice” (1602) to the violin études of Mazas (1843). In the Baroque sound world, free from the all-pervasive vibrato of modern times, it was the responsibility of the bow to provide this ‘inner life of sound.’ Based mainly on the writings of Tartini, Geminiani, and Leopold Mozart, all of whom are quoted, this lesson contains five exercises for perfecting the expressive device that guaranteed this living sound, the “Messa di voce.” The many different aspects of its technique, gleaned from the sources, are isolated and explained in detail, from simple pressure with the forefinger to the addition of vibrato: two composers who indicated this device in their compositions, Veracini and Piani, are quoted and illustrated.

Abstract:
Abstract Violent vibration occurred at high-pressure turbine of a turbo-generator. When steam input or load capacity was changed, the vibrations were also varied. Wavelet packets, FFT spectrum and cepstrum were adopted synthetically to obtain diagnosis information. According to signal analyses and factual evidences, it was clear that there existed violent vibration (be nonlinear) excited by steam in high-pressure turbine. We investigated the maintenance conditions, and found that the four main pipes of steam input had different lengths after their thermal expansion, which lead to skew at the body of high-pressure turbine. The intervals between rotor and stator were non-uniform. So, besides a moment of couple was generated onto the rotor, a force was also generated. This force excited the rotor of the high-pressure turbine to vibrate with its natural frequency. After repairing the four main pipes, its vibration became normal as the turbo-generator was running. It is important to combine signal processing with practical investigation. Only in this way can we obtain correct diagnosis results and achieve successful maintenance.

Abstract:
Abstract In Engineering, Vehicles in motion which undergo some random excitation given by the surroundings, may result in violent vibrations. The calculated results indicate that: 1) the softening nonlinear spring isolator usually is effective. 2) In the vibration system, sometimes, added more damping meterial can not effectively isolate the vibration of vehicles. But choosing the reasonable forms of nonlinear structures just is a effective isolating method.

Abstract:
Abstract The contacting point between belt and pulley is not fixed but moves along the pulley during vibration and that influences the free span length of the belt. The concept vibrating length is introduced and that will affect the dynamic behavior of the belt. Parametric excitation can occur through periodic variations in belt tension and speed arising from loading of the pulleys by belt-driven accessories and from engine in automotive applications. The most violent oscillations develop and resonance will occur when the frequency of excitation is close to twice or three times the natural frequency for varying tension and speed case, respectively.

Full text
Abstract:
This paper presents cross-flow induced response of a both-end-spring-mounted circular cylinder (diameter D) placed in the wake of a rigid circular cylinder of smaller diameter d. The cylinder vibration is constrained to the transverse direction. The cylinder diameter ratio d/D and spacing ratio L/d are varied from 0.2 to 1.0 and 1.0 to 5.5, respectively, where L is the distance between the center of the upstream cylinder to the forward stagnation point of the downstream cylinder. A violent vibration of the cylinder is observed for d/D = 0.2 ∼ 0.8 at L/d = 1.0, for d/D = 0.24 ∼ 0.6 at 1.0 < L/d ≤ 2.5, for d/D = 0.2 ∼ 0.4 at 2.5 < L/d ≤ 3.5, and for d/D = 0.2 at 3.5 < L/d ≤ 5.5, but not for d/D = 1.0. A smaller d/D generates vibration for a longer range of L/d. The violent vibration occurs at a reduced velocity Ur (=U∞/fnD, where U∞ is the free-stream velocity and fn the natural frequency of the cylinder system) beyond the vortex excitation regime (Ur ≥ 8) depending on d/D and L/d. Once the vibration starts to occur, the vibration amplitude increases rapidly with increasing Ur. It is further noted that the flow behind the downstream cylinder is characterized by two predominant frequencies, corresponding to the cylinder vibration frequency and the natural vortex shedding frequency of the cylinder, respectively. While the former persists downstream, the latter vanishes rapidly.

Abstract:
Abstract A marimba bar makes a rich and vibrant sound when played by a skilled musician. When that same marimba bar is played by the typical mechanical engineering junior, it’s a different story. Then, that same marimba key provides a complex set of vibration modes that are a useful subject for a lab experiment in their Measurements & Instrumentation course. This paper will describe development of “The Marimba Experiment”, which is part of a junior-level engineering course in measurements at Milwaukee School of Engineering. Learning outcomes for this course include “provide students with hands-on experience: using various sensors, performing data collection, and interpretation of experimental results.” In this experiment, students measure vibrations using a piezoelectric accelerometer, charge amplifier and analog-to-digital conversion. Results can be viewed in two ways. First, it may be interpreted as a general example of a vibrating structural component. It has several natural frequencies and mode shapes (transverse bending, lateral bending, torsional), which are simultaneously active. The signal represents an example of a complex periodic signal. It may be analyzed by looking at the acceleration versus time response and by examining the Fourier transform of the data, which shows results in the frequency domain. Second, results may be interpreted in musical terms. The lowest frequency is what we recognize as “the note” and the higher modes represent the higher harmonics. The distribution of frequency ratios and the relative amplitudes of the higher frequencies are what gives a musical instrument its unique character. In other words, what makes middle-C on a marimba sound different than middle-C on a clarinet or violin? A well-designed engineering experiment can give students an immediate application example. In this case, it is an example which they spontaneously want to explore because they all enjoy music and want to understand how it is created.

Abstract:
The vibro-acoustic environment inside a launch vehicle payload fairing is extremely violent resulting in excessive development costs for satellites and other payloads. The development of smart structures and active noise and vibration control technologies promised to revolutionize the design, construction and, most importantly, the acoustic environment within these fairings. However, the early promise of these technologies has not been realized in such large-scale systems primarily because of the excessive complexity, cost and weight associated with centralized control systems. Now, recent developments in MEMS sensors and actuators, along with networked embedded processor technology, have opened new research avenues in decentralized controls based on networked embedded systems. This work describes the development and comparison of decentralized control systems that utilize this new control paradigm. The controllers are hosted on numerous nodes, possessing limited computational capability, sensors and actuators. Each of these nodes is also capable of communicating with other nodes via a wired or wireless network. The constraints associated with networked embedded systems control that the control systems be relatively simple computationally, scalable and robust to failures. Simulations were conducted that demonstrate the ability of such a control architecture to attenuate specific structural modes.

Abstract:
The rotor-fluid film bearing systems are widely used in machinery due to their small size, low price, and capability of carrying load. However, if its design and manufacturing is inappropriate, the use of rotor-fluid film bearing system will suffers from some problem such as violent vibration. Although the checking calculation has been carried out during the design process, nominal value of design parameters is usual used to prognosis the vibration characteristics of rotor-fluid film bearing system. However, in practice, these parameters always vary within a certain range due to manufacturing tolerances and variation of working environment. In this paper, a model for simulating the performance of rotor-fluid film bearing system has been established. Monte Carlo analysis was performed to evaluate the effects of manufacturing tolerances and variation of working environment on the rotor vibration. In the end, a uncertainty analysis is carried out to demonstrate which of the factors has the greatest effect on the rotor vibration at different rotational speed.

Abstract:
This study presents 3-D model gate vibration test results demonstrating violent spontaneous vibrations and validating the basic assumptions made in previously published theoretical analyses. First, the design of a 1/13-scaled 3-D model of Folsom dam Tainter-gate is presented, in which the streamwise natural bending vibration mode of the skinplate, measured in the field vibration tests on the remaining Folsom gate, is shown to be correctly replicated with the aid of FEM simulations. Secondly, in-air and in-water vibration test results with the 1/13-scaled 3-D model are presented, reproducing the intense coupled-mode self-excited vibrations. Thirdly, test results are plotted on a theoretically calculated stability criterion diagram to confirm the validity of the theoretical analysis. Finally, the intense dynamic instability of the Folsom gate, which could have caused its failure, is presented.
