The VSA-Oberlin Acoustics Workshop
Co-Sponsored by the CAS Forum
June 10-17, 2016

The VSA-Oberlin Acoustics workshop brings together violin-makers and researchers for a week of hands-on projects, talks, and demonstrations. Now in its 16th year, the upcoming session will run concurrently with the first week of the violin and bow making workshops, allowing opportunities for joint projects.

Expanding our vision of integrating high-level performance into the workshop, violinist Nathan Giem (concertmaster of the Hungarian Radio Symphony Orchestra) will return as music director, along with Cristian Fatu (assistant concertmaster of the West Virginia Symphony orchestra), and other artists to be announced. All will take part in blind tests, give feedback on participant instruments, and celebrate the player-maker relationship in recitals performed on violins, violas, and cellos from the workshop.

Space in the workshop is limited. If you are interested, please contact Fan Tao at Fan.Tao@Daddario.com as soon as possible to reserve a space.
 
Below are four projects we are considering for the upcoming session. Please let us know which interest you most, or if you have a project of your own you would like to pursue.

Bridge Optimization

In 2004 we conducted a seminal experiment on bridge tuning. The results were published in a 2006 scientific paper, “The violin bridge as filter,” by George Bissinger. This year, Joseph Curtin will take a fresh look at the original data, and consider its importance for violin-makers. He will also lead a follow-up study that will help us better understand the possibilities for optimizing individual violins via bridge-tuning. Participants are asked to bring an instrument fitted with a bridge they are prepared to incrementally destroy.

Bassbar Project

How high should a bassbar be? Can we predict the tonal effects of lowering it? Very little research has been done in this area – meaning a lot can be learned from a well-controlled experiment. Participants are asked to bring a violin which they are prepared to open and close one or more times during the session.

                                                                                  Loudness, Projection, & Preference
 
The violin world has long distinguished between the loudness of a violin and its projection, but recent research shows a surprisingly close relationship between the two. This year we will explore how loudness and projection relate to listener preference by means of two blind listening tests in the hall – one for violin, the other for viola.
                
Measuring Cellos
 
We now have well-developed methods for measuring violin and viola sound radiation using an Impact Hammer Rig. Last year a group led by Evan Davis, Chris Dungey, and Colin Gough began developing a rig for measuring cellos. The work continues this summer.
 
Faculty Bios
 
This year’s faculty include George Bissinger, Joseph Curtin, Evan Davis, Claudia Fritz, Colin Gough, George Stoppani, and Fan Tao.

George Bissinger, is Emeritus Professor of Physics at East Carolina University and as Director of the Acoustics Laboratory, developed the most comprehensive violin measurement system ever put together. Based on impact hammer excitation, it uses a scanning laser vibrometer for modal analysis, and an array of microphones for radiation measurements. His VIOCADEAS project is a comprehensive vibrational and acoustical characterization of a set of quality-rated violins, including two Strads and a Guarneri del Gesu. Bissinger was the research director for the Strad 3D Project.
 
Joseph Curtin, co-director of the Workshop, is a violinmaker, writer, and researcher whose interests range from traditional violins to experimental instruments using alternative materials and architectures. Curtin has collaborated with many researchers, including Gabriel Weinreich, Claudia Fritz, and Charles Besnainou. He lectures frequently on violin acoustics, is a regular contributor to The Strad, and wrote (with co-author Thomas Rossing) the chapter on violin acoustics in the textbook published by Springer, “The Science of Musical Instruments.” In 2005 Curtin was awarded a MacArthur Fellowship.
 
Evan Davis was a Technical Fellow at the Boeing Commercial Aircraft Company, where he led their structural acoustics research group. Davis is a recognized expert in the field of Statistical Energy Analysis, a method for modeling and analyzing complex structural acoustic responses in the mid-to-high audio frequency range. His early fascination with guitars led to the construction of several instruments, and to a PhD in guitar acoustics from the University of Washington. He joined the Catgut Acoustical Society in 1976, and is on the Editorial Board of the VSA Journal: Proceedings. Davis has worked with some of world’s leading guitar builders on ‘out of the box’ projects. He performs with several bands as a jazz drummer and a gypsy jazz guitarist.
 
Claudia Fritz is a CNRS-researcher in Paris, and a member of the Lutherie-Acoustics-Music team at the University Pierre & Marie Curie. Following her post-doctoral work at the University of Cambridge (UK), she has been investigating the correlations between player and listener perceptions and measured acoustical properties. Her recent work with double-blind studies involving new and old violins has gained widespread international attention. 

Nathan Giem is currently first concertmaster of the Hungarian Radio Orchestra, and has served as concertmaster of the Tokyo Philharmonic Orchestra, and as guest concertmaster of the Los Angeles Camerata Orchestra for its 2004 tour of China. A student of Franco Gulli and Alexander Kerr (among others), he received a 2005 Fulbright Scholarship to study Orchestral Leadership in the Netherlands. Giem has since performed as a soloist, chamber musician and concertmaster across Europe, Japan and the United States.

Colin Gough is an Emeritus Professor of Physics at the University of Birmingham, England, where he headed the UK’s largest interdisciplinary research group on superconductivity. An avid amateur violinist, Gough led the University’s Hayward String Quartet and many other local chamber and orchestral groups. He has enjoyed a long-term interest in violin acoustics, and in the factors determining sound quality. In addition to teaching Musical Acoustics, he has published major research articles on vibrating strings, the wolf note, and vibrato, from both the scientific and the player/listener’s points of view. In 2001, Gough received the annual Science Writing Award for Professionals in Acoustics for an article about violin acoustics. He wrote the Musical Acoustics section of a major Handbook on Acoustics published by Springer, and has recently published several important papers describing and explaining the vibrations and sounds of the violin and related instruments.
 
George Stoppani started out studying Literature and Music at York University before turning to instrument making in the mid-seventies. At first most of his work was with period instruments but currently it is mostly modern violins. He has also built many cellos and basses. An off-shoot of the period instruments is “Real Guts” strings, which is a quasi-cooperative making strings for historic instruments. Stoppani has been deeply involved with acoustic research with the development of software specifically for modal analysis and other measurements of string instruments. This led to him being an invited speaker at the SMAC13 conference in Stockholm. He has also given talks at numerous workshops and conferences in the United States and Europe and has written for a number of publications including the Strad and the CAS journal. In addition he takes part in many collaborative projects with other instrument makers. 
 
Fan-Chia Tao, co-director, is Director of Research and Development at D’Addario & Company, where he works on bowed-instrument and guitar strings. His interest in violin acoustics was fostered by his mentor Norman Pickering. An accomplished violinist and violist, Tao is an avid chamber music player. He holds electrical engineering degrees from Caltech and Princeton University. He is a Trustee of the CAS Forum (formerly Catgut Acoustical Society) and is the President of the Violin Society of America.
