Two of the Most Challenging Concepts of Vocal Technique Are Registration and Vowel Modification ABSTRACT Title of Dissertation: TEACHING REGISTRATION IN THE MIXED CHORAL REHEARSAL: PHYSIOLOGICAL AND ACOUSTICAL CONSIDERATIONS Nicole Aldrich, Doctor of Musical Arts, 2011 Dissertation directed by: Prof. Edward Maclary School of Music One of the most challenging concepts of vocal technique is registration. In classical Western singing, noticeable changes of timbre over the course of a singer‟s vocal range are considered undesirable, and much effort is spent in learning how to eliminate these “breaks.” Faults in vocal registration can cause unevenness of tone quality, lack of resonance, and instability of intonation. The choral conductor must learn how to address these problems in rehearsal in order to establish good choral sound. Much literature exists which defines the physiological and acoustical adjustments required to create a well-blended, “one-register” voice; however, this literature is aimed at the individual singer or teacher of solo voice. Voice-training resources for choral conductors may mention registration and vowel modification but typically do not explain in any detail the science underlying the concepts. The choral conductor thus must adapt the body of solo voice research for application to a group voice teaching setting. The primary goal of this paper is to propose and describe techniques for teaching registration and vowel modification concepts to choral singers. The paper details the physiological factors at work in vocal registration, including the functions of the intrinsic laryngeal musculature. It also surveys the science of acoustics as it applies to the singing voice, including a discussion of vowel formants and the purposes and methods of formant tuning for male and female voices. This section will draw heavily on existing research in solo singing. The next portion of the paper tailors this knowledge to the needs of the choral vocal teacher. The author describes signs of registration difficulties within an ensemble and their possible causes. Next the author provides a series of vocalises and other tools designed to help the conductor achieve two goals in rehearsal: first, to help both men and women develop the physiological adjustments necessary to reduce obvious registration shifts; and second, to assist singers of all voice types in discovering the vowel modifications which will produce a uniform tone quality throughout the range. Finally, the author explains how the conductor can identify potential registration problems during score study and preparation.

A. Mozart’s opera and concert arias for tenor are among the first music written specifically for this voice type as it is understood today, and they form an essential pillar of the pedagogy and repertoire for the modern tenor voice. Yet while the opera arias have received a great deal of attention from scholars of the vocal literature, the concert arias have been comparatively overlooked; they are neglected also in relation to their counterparts for soprano, about which a great deal has been written. There has been some pedagogical discussion of the tenor concert arias in relation to the correction of vocal faults, but otherwise they have received little scrutiny. This is surprising, not least because in most cases Mozart’s concert arias were composed for singers with whom he also worked in the opera house, and Mozart always paid close attention to the particular capabilities of the musicians for whom he wrote: these arias offer us unusually intimate insights into how a first-rank composer explored and shaped the potential of the newly-emerging voice type of the modern tenor voice.

    THE DOUBLE REED 103 Second Bassoon: Specialist, Support, Teamwork Dick Hanemaayer Amsterdam, Holland (!e following article first appeared in the Dutch magazine “De Fagot”. It is reprinted here with permission in an English translation by James Aylward. Ed.) t used to be that orchestras, when they appointed a new second bassoon, would not take the best player, but a lesser one on instruction from the !rst bassoonist: the prima donna. "e !rst bassoonist would then blame the second for everything that went wrong. It was also not uncommon that the !rst bassoonist, when Ihe made a mistake, to shake an accusatory !nger at his colleague in clear view of the conductor. Nowadays it is clear that the second bassoon is not someone who is not good enough to play !rst, but a specialist in his own right. Jos de Lange and Ronald Karten, respectively second and !rst bassoonist from the Royal Concertgebouw Orchestra explain.) BASS VOICE Jos de Lange: What makes the second bassoon more interesting over the other woodwinds is that the bassoon is the bass. In the orchestra there are usually four voices: soprano, alto, tenor and bass. All the high winds are either soprano or alto, almost never tenor. !e "rst bassoon is o#en the tenor or the alto, and the second is the bass. !e bassoons are the tenor and bass of the woodwinds. !e second bassoon is the only bass and performs an important and rewarding function. One of the tasks of the second bassoon is to control the pitch, in other words to decide how high a chord is to be played.

  • 1 Making the Clarinet Sing
    Making the Clarinet Sing: Enhancing Clarinet Tone, Breathing, and Phrase Nuance through Voice Pedagogy D.M.A Document Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Musical Arts in the Graduate School of The Ohio State University By Alyssa Rose Powell, M.M. Graduate Program in Music The Ohio State University 2020 D.M.A. Document Committee Dr. Caroline A. Hartig, Advisor Dr. Scott McCoy Dr. Eugenia Costa-Giomi Professor Katherine Borst Jones 1 Copyrighted by Alyssa Rose Powell 2020 2 Abstract The clarinet has been favorably compared to the human singing voice since its invention and continues to be sought after for its expressive, singing qualities. How is the clarinet like the human singing voice? What facets of singing do clarinetists strive to imitate? Can voice pedagogy inform clarinet playing to improve technique and artistry? This study begins with a brief historical investigation into the origins of modern voice technique, bel canto, and highlights the way it influenced the development of the clarinet. Bel canto set the standards for tone, expression, and pedagogy in classical western singing which was reflected in the clarinet tradition a hundred years later. Present day clarinetists still use bel canto principles, implying the potential relevance of other facets of modern voice pedagogy. Singing techniques for breathing, tone conceptualization, registration, and timbral nuance are explored along with their possible relevance to clarinet performance. The singer ‘in action’ is presented through an analysis of the phrasing used by Maria Callas in a portion of ‘Donde lieta’ from Puccini’s La Bohème. This demonstrates the influence of text on interpretation for singers.

  • The New Dictionary of Music and Musicians
    The New GROVE Dictionary of Music and Musicians EDITED BY Stanley Sadie 12 Meares - M utis London, 1980 376 Moda Harold Powers Mode (from Lat. modus: 'measure', 'standard'; 'manner', 'way'). A term in Western music theory with three main applications, all connected with the above meanings of modus: the relationship between the note values longa and brevis in late medieval notation; interval, in early medieval theory; most significantly, a concept involving scale type and melody type. The term 'mode' has always been used to designate classes of melodies, and in this century to designate certain kinds of norm or model for composition or improvisation as well. Certain pheno­ mena in folksong and in non-Western music are related to this last meaning, and are discussed below in §§IV and V. The word is also used in acoustical parlance to denote a particular pattern of vibrations in which a system can oscillate in a stable way; see SOUND, §5. I. The term. II. Medieval modal theory. III. Modal theo­ ries and polyphonic music. IV. Modal scales and folk­ song melodies. V. Mode as a musicological concept. I. The term I. Mensural notation. 2. Interval. 3. Scale or melody type. I. MENSURAL NOTATION. In this context the term 'mode' has two applications. First, it refers in general to the proportional durational relationship between brevis and /onga: the modus is perfectus (sometimes major) when the relationship is 3: l, imperfectus (sometimes minor) when it is 2 : I. (The attributives major and minor are more properly used with modus to distinguish the rela­ tion of /onga to maxima from the relation of brevis to longa, respectively.) In the earliest stages of mensural notation, the so­ called Franconian notation, 'modus' designated one of five to seven fixed arrangements of longs and breves in particular rhythms, called by scholars rhythmic modes.

  • Laker Drumline Marching Bass Drum Technique
    Laker Drumline Marching Bass Drum Technique This packet is intended to define a base framework of knowledge to adequately play a marching bass drum at the collegiate level. We understand that every high school drumline has its own approach to technique, so it’s crucial that ALL prospective members approach their hands with a fresh mind and a clean slate. Mastery of the following concepts & terminology will dramatically improve your experience during the audition process and beyond. Happy drumming! APPROACH The technique outlined in this packet is designed to maximize efficiency of motion and sound quality. It is necessary to use a high velocity stroke while keeping your grip and your muscles relaxed. Keep these key points in mind as you work to refine the music in this packet. Tension in your upper body, lack of oxygen to your muscles, and squeezing the stick are good examples of technique errors that will hinder your ability to achieve the sound quality, efficiency, and control that we strive for. GRIP Fulcrum Place the mallet perpendicularly across the second segment of your index finger. Place your thumb on the mallet so that the thumbnail is directly across from your index finger. ** This is the essential point of contact between your hands and the stick. It should be thought of as the primary pressure point in your fingers and pivot point on the stick. The entire pad of your thumb should remain in contact with the mallet at all times. As a bass drummer, about 60% of the pressure in your hands should lie in the fulcrum.

These registers are: loft, which is the highest of the three, and could be described perceptually as the “falsetto” range; modal, which is the middle range and is evident in “normal” speech production; and pulse, the lowest range of phonation that is characterized by popping, pulsing sounds.

There is similarly a growing body of research into the system of voice classification and repertoire assignment. This paper shall reexamine this research in light of baritenor voices. After establishing the general parameters of healthy vocal technique through appoggio, the various tenor, baritone, and bass Fächer will be studied to establish norms of vocal criteria such as range, timbre, tessitura, and registration for each Fach. The study of these Fächer includes examinations of the historical singers for whom the repertoire was created and how those roles are cast by opera companies in modern times.

  • A Countertenor's Reference Guide to Operatic Repertoire
    A COUNTERTENOR’S REFERENCE GUIDE TO OPERATIC REPERTOIRE Brad Morris A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF MUSIC May 2019 Committee: Christopher Scholl, Advisor Kevin Bylsma Eftychia Papanikolaou © 2019 Brad Morris All Rights Reserved iii ABSTRACT Christopher Scholl, Advisor There are few resources available for countertenors to find operatic repertoire. The purpose of the thesis is to provide an operatic repertoire guide for countertenors, and teachers with countertenors as students. Arias were selected based on the premise that the original singer was a castrato, the original singer was a countertenor, or the role is commonly performed by countertenors of today. Information about the composer, information about the opera, and the pedagogical significance of each aria is listed within each section. Study sheets are provided after each aria to list additional resources for countertenors and teachers with countertenors as students. It is the goal that any countertenor or male soprano can find usable repertoire in this guide. iv I dedicate this thesis to all of the music educators who encouraged me on my countertenor journey and who pushed me to find my own path in this field. v PREFACE One of the hardships while working on my Master of Music degree was determining the lack of resources available to countertenors. While there are opera repertoire books for sopranos, mezzo-sopranos, tenors, baritones, and basses, none is readily available for countertenors. Although there are online resources, it requires a great deal of research to verify the validity of those sources.

Davies, Co-Chair Professor Mary Ann Smart Professor Massimo Mazzotti Summer 2015 Keyboard Playing and the Mechanization of Polyphony in Italian Music, Circa 1600 Copyright 2015 by Leon Chisholm Abstract Keyboard Playing and the Mechanization of Polyphony in Italian Music, Circa 1600 by Leon Chisholm Doctor of Philosophy in Music University of California, Berkeley Professor Kate van Orden, Co-Chair Professor James Q. Davies, Co-Chair Keyboard instruments are ubiquitous in the history of European music. Despite the centrality of keyboards to everyday music making, their influence over the ways in which musicians have conceptualized music and, consequently, the music that they have created has received little attention. This dissertation explores how keyboard playing fits into revolutionary developments in music around 1600 – a period which roughly coincided with the emergence of the keyboard as the multipurpose instrument that has served musicians ever since. During the sixteenth century, keyboard playing became an increasingly common mode of experiencing polyphonic music, challenging the longstanding status of ensemble singing as the paradigmatic vehicle for the art of counterpoint – and ultimately replacing it in the eighteenth century. The competing paradigms differed radically: whereas ensemble singing comprised a group of musicians using their bodies as instruments, keyboard playing involved a lone musician operating a machine with her hands.
