Choral Resonance: Re-Examining Concepts of Tone and Unification.

Quist, Amanda Renee 08 1900 (has links)
Resonant singing creates possibilities with dynamic shading, subtlety of phrasing, and rich vibrant tone that astonishes listeners. Choral singing that employs resonance as a fundamental ensemble virtue yields impressive results that lend themselves well to the varying demands of any choral score. Fortunately, choruses of every level can benefit from an increased understanding of the basic principles of resonance in the singing voice. Research on issues of upper partial energy and the presence of the singer's formant in a choral ensemble has been limited in approach. Many published studies regarding upper partial energy in the choral ensemble are based on what the ensemble is already doing, which is linked to the teaching of that specific director and that specific choir. Research must include a wider range of aesthetic choices with regard to choral unification. Through examining spectrograms that represent the sound of some of the most renowned choirs, it is possible to see that many of these ensembles are producing tone that contains a high level of upper formant energy. Interviews with established conductors reveal approaches and teaching methodologies that reinforce this type of singing. It is possible to teach the individuals in a choir to increase the level of resonance in their voices, creating a collective sound containing a vibrancy that is easier to tune and unify. This paper explores resonance in choral singing by first explaining the basic principles of sound production, then defining a resonant tone as one containing the strong presence in the upper partials generally associated with classically trained singers, and finally discussing how this type of resonance is developed in choirs.

A Comparison of the Acoustical Properties in Solo and Ensemble Performance of the Trombone

Himes, Addison Choate 12 1900 (has links)
The specific problems investigated involved identifying and describing the characteristics of fundamental frequency, overall intensity, and spectral content in unaccompanied and ensemble performance settings. Additionally, comparisons and descriptions of the relationships among these acoustical parameters were made. Fifteen trombonists were used as research subjects. Each subject recorded a selected musical excerpt in the following performance modes: high register unaccompanied, harmonic, and unison ensemble; and low register unaccompanied and unison ensemble. Tape recordings of these subjects were used in conjunction with certain electronic apparatus to obtain data on frequency, intensity, and spectral content. Based on these data, descriptions of these acoustical parameters and comparisons of unaccompanied and ensemble performance settings were made.

Mathilde Marchesi: a study of her life and work in vocal pedagogy, including historical and modern implications

Unknown Date (has links)
Mathilde Marchesi played a significant role in vocal education during the nineteenth and early twentieth centuries. Marchesi taught many of the prominent female vocalists of her time and published a wealth of material based on the bel canto style and her own vocal methods. The research presented includes an examination of musical influences in early years, and provides information related to Marchesi's studies with Manuel Garcia II who played an important role in Mathilde's training and future devotion to the bel canto style. Section II defines the Marchesi method, with analysis of her techniques and methodology. Information on three of her most well known students - Nellie Melba, Emma Eames, and her own daughter, Blanche Marchesi, is presented in Section III along with narrative offering insight into Marchesi's personality and character. The thesis concludes with discussion of the viability and applicability of Marchesi's vocal pedagogy one hundred years after her death. / by Joanna Craik. / Thesis (M.A.)--Florida Atlantic University, 2011. / Includes bibliography. / Electronic reproduction.

A Study of the Effects of Frequency Variance on Duration Perception

Gay, Leslie C. 05 1900 (has links)
This study investigates the effects of frequency variance on duration perception, using musically trained subjects. In the experiment three silent duration intervals were examined (4.75, 5.00, and 5.25 seconds); each interval was preceded and followed by tone markers. The onset marker was preceded by seven discrete tones one second apart, on the frequency 174.968 Hertz. This established a pulse or an external standard time measure. The subjects made judgments as to whether the offset marker fell "before," "on," or "after," the pulse. The offset marker had a variable frequency. In the study, the direction of the frequency change, the distance of frequency change, and the mathematical intervallic relationships of the two frequencies show possible influence on duration perception.

Para adequar à acústica destes espaços para a música orquestral é necessário o uso de elementos que possibilitem a variação acústica do espaço como é o caso de conchas de orquestra. O principal objetivo das conchas de orquestra é melhorar a acústica no palco para os músicos e para o maestro, melhorando a sensação de conjunto e fazendo com que os músicos ouçam melhor seus instrumentos e o grupo em geral. Entretanto, a concha de orquestra pode também melhorar o desempenho acústico da área da platéia. A hipótese deste trabalho foi o de analisar a diferença do desempenho acústico percebido na área da platéia devido à inclusão de uma concha de orquestra no palco de um teatro de múltiplo uso. Medições acústicas foram realizadas em cinco diferentes tipos de montagem da concha de orquestra no palco. As medições foram feitas de acordo com a norma ISO 3382-1 (2009). Os parâmetros acústicos medidos foram o Tempo de Reverberação, Tempo Inicial de Decaimento e Índice de Clareza. Os resultados mostraram que a concha de orquestra pode de fato mudar o desempenho acústico na área da platéia, modificando a percepção acústica subjetiva do ambiente / Abstract: The construction of multiple use theatres is becoming more common due to the need to accommodate different kinds of performances at the same space. In order to acoustically adequate this space to concert music, the inclusion of an orchestra shell becomes necessary. The main objective of an orchestra shell is to improve the acoustic quality on stage, both for musicians and for the conductor. The goal is to improve balance of the group allowing musicians to hear themselves and the orchestra better. However, the orchestra shell can also improve the acoustic quality for the audience. The objective of this study was to analyze the difference of the acoustic performance perceived at the audience area with the inclusion of a lightweight orchestra shell with diffuse surface in a proscenium theatre. Acoustic measurements were done in five different assembles of the orchestra shell. Measurements were done using the impulse response technique according to ISO3382-1 (2009). Measured parameters were Reverberation Time, Early Decay Time and Clarity index. Results showed that the orchestra shell can in fact modify the acoustic performance at audience area, changing the subjective acoustic perception of the space / Mestrado / Arquitetura e Construção / Mestre em Engenharia Civil
