Listening to the Past: The Effects of Historical Recording Technology on the Singing Voice

Our understanding of historical singing and the methods used by historical voice pedagogues is potentially limited by the technology used to record historical singers. Previous studies of the effects of wax cylinder phonographs have found distortions that may influence our perception of singing features or cause listeners to make judgements about performance practice and training ca. 1880-1930 (Feynberg, 2014; Zakaria, 2016; Glasner, 2019; Glasner & Johnson, in press).   As such, any discussion about the origins of microphone technology and the resultant changes to vocal techniques may benefit from an understanding of the audio recording technologies that directly preceded the microphone and the limitations of the earliest form of recording technology--the wax cylinder phonograph.

This lecture will present the results of a multi-faceted study of the wax cylinder phonograph system that recorded and analyzed professional opera singers in New York (in collaboration with the Thomas Edison National Historical Park) using a flat-response microphone array and an Edison Home Phonograph.  These analyses clearly demonstrate the effect of historical recording technology on aspects of the singing voice such as vibrato rate, vibrato extent, fundamental frequency, and various spectral measurements.  They also describe the way in which historical recording technology systems distort and limit the frequency range of audio recordings of singers.  Additionally, this presentation will discuss the historical development of microphone technology and how listeners might interpret historical acoustic and electric/digital recordings based on an understanding of frequency response curves, signal distortion (e.g. clipping), and perception of the singing voice.  By doing so, this lecture aims to enhance discussions related to the development of the singing voice and modern-day singing techniques as well as promote conversations amongst voice professionals about the development of voice pedagogy throughout the last 140 years.

The NATS “So You Want to Sing Series”: Reflections on Seven Years, Twenty Books, and a Glimpse of the Future –

So You Want to Sing: Guides for Performers is a series of works devoted to providing a complete survey of what it means to sing within a particular genre or explore a specific pedagogical question. Each contribution functions as a touchstone work for not only professional singers, but also students and teachers of singing. Titles in the series offer a common set of topics so readers can navigate easily the various genres and styles addressed in each volume. The So You Want to Sing series is a joint venture between NATS and Rowman & Littlefield with individual volumes written by experts that hail from within the ranks of NATS and beyond into our larger profession. As of the 2022 ICVT Conference in Vienna, twenty books have been published covering a wide array of genres including musical theatre, rock ‘n’ roll, jazz, gospel, country, sacred music, barbershop, folk, light opera, a cappella, CCM, blues, early music, chamber music, world music, spirituals, and cabaret. After a formal introduction of the series, Henderson and Hoch will each describe their role in bringing the So You Want to Sing series to life, after which panelists will have the opportunity to share their personal story and journey through the book-writing process. The session will conclude with an opportunity for attendees to ask questions and engage in discussion with the presenters.

Mindfulness for Singers: Benefits for Practice and Performance

Peak performance and effective practice can only be achieved with mental calm and clarity. Some musicians seem to innately possess it: others must learn it. Mindfulness meditation helps to level the playing field. It provides performing artists the tools to manage performance anxiety, access mental quietude, and improve focus and memory retention. This interactive workshop requires a moderately quiet room.

The ability to redirect thoughts helps all artists endure the marathon of developing our craft, the harrowing process of auditioning with both positive and negative results, and for working under a variety of circumstances. This workshop explores Koru mindfulness, which is based on Mindfulness-Based Stress Reduction (MBSR), an eight-week evidence-based program developed at the University of Massachusetts Medical Center in the 1970s. Jon Kabat-Zinn (1990) and Shapiro, Schwartz & Bonner (1998) note the many positive physical and psychological benefits of mindfulness training. 

Meditation has been proven through many recent scientific studies to change the size and function of the brain and has direct application to performers. Meditation helps performers develop awareness without judgment, key to reducing performance anxiety and to focused, effective practice. The Center for Koru Mindfulness was developed by psychiatrists and social workers at Duke University ten years ago to help emerging adults (those aged 18-30) manage stress.

Before the pandemic, Koru served as the centerpiece of wellness seminars in the Honors College. During the pandemic, demand for stress management via mindfulness meditation was so great that the submitter of this proposal contributed over thirty online meditation workshops through the Mental Health Ambassadors at her institution, at national and regional workshops, and at other universities. Overwhelming positive response in both classroom and workshop settings matches with studies by Jon Kabat-Zinn and others. This presenter is the only Koru-certified teacher in her state of residence.

While time does not allow us for a full overview of Koru—certification includes a three-day workshop and teaching three 4-week classes—attendees will have a taste of Koru by learning several of the skills taught by Koru teachers. A creative visualization mediation, which is especially useful for managing performance anxiety, will be included.


The human voice has been my favourite instrument for as long as I can remember. Therefore, voice and/or music has been a common thread in my trainings (among other things I led the choir of „pro mente“ = Society for psychological and social health, Vienna, as part of the psychotherapeutic preparatory course).

Not being pigeonholed could be my motto. My versatility is reflected in my trainings: Besides above mentioned qualifications, I am a trained teacher for tourism school and I hold a diploma in literary writing and in integrative riding and vaulting pedagogy. What seems incoherent at first glance quickly makes a deeper sense because if I had to summarise my interests in three words, they would be „people, music and language“. This explains my passion for looking at the human psyche and playing with words until the right tone is struck.

Stage Fright and Breathing . Interrelation effects Power. With Mental Training to a more expressive and sound voice

The aim of this workshop is to show how stage fright effects performing with the voice; Why breathing is the key problem of all effects of stage fright – and therefore the key solution for all those problems and effects.The workshop includes:

Short theoretical summary and practical exercises.

Acting the Song: Tactics for Lyric Theater Artists

Although differing in many stylistic aspects of performance, the singers of opera and musical theatre share the inherent need to honestly portray the emotions and given circumstances of their characters. With the recent and potentially permanent shift to filming and live-streaming theatrical performances, possessing proficient acting skills is increasingly imperative for a professional singing career in all media. The essence of any acting through singing involves what one is doing from moment to moment, both physically and emotionally. By analyzing the given circumstances and objectives of the character, participants can create the basis of a unique and confident physical and vocal performance. Additional acting clues are found externally in the orchestration, musical structure, and punctuation. Taking note of this guidance from the composer and lyricist guides theatre artists to make informed and authentic acting choices. Through acting exercises and the use of familiar repertoire, attendees will learn to recognize and analyze these clues from the source material and apply them to their own interpretation and performance.   Attendees will gain a shared understanding of practical acting strategies and techniques to use in the voice studio to enhance the professional acting abilities of their voice students.

„Singers . what theatres really need?“

A cynical, but unfortunately not completely wrong approach to our question: theaters want to sell tickets, so they need singers who do this for them, to be “marketed” well. The fact that attractive portrait photos often have more effect than a solid artistic basis and that the eyes sometimes gain the upper hand over the ears in auditions is unfortunately also to be observed. Closer (and less cynically) viewed, the demands on singers today are greater than ever: They must be flexible musicians who not only learn their parts by ear, but who are able to understand the musical text and from it form their own interpretations (not clones of YouTube and CD recordings); they should be versed in a wide range of musical styles; they must be agile performers in order to be able to respond to the requirements of each stage direction or possibly even choreography. We expect storytellers who can handle their voice, language and body equally well.

This leads to questions concerning training: Is it sufficient for singers to sing, actors to act and dancers to be able to dance? Or should it be necessary, at least at the beginning of their studies, that an "integrated" training be prioritized to become a performer and later each specialization take place? Does it make sense to let teachers loose on students who they themselves have little or no stage experience?

And what part do role models play? Is it opportune to imitate the most famous contemporary stars (paid the highest fee) to reach their goals? The great Danish tenor and pedagogue Aksel Schiotz prefaced his standard work "The Singer and his Art" with a quote by Ralph Waldo Emerson: „Insist on yourself; never imitate.

Your own gift you can present every moment with the cumulative force of a whole life’s cultivation; but of the adopted talent of another you have only an extemporaneous half possession”.
