The Journal of Guitar Acoustics Tim White, editor
a listing of the contents
As a former research scientist, I have always wanted to know more about the technical side of how the ukulele and guitar function. Much of this information is difficult to obtain for the average person not having access to extensive library sources. Then I was able to get the back issues of the Journal of Guitar Acoustics from Tim White. I had heard reference to such material before but was never able to obtain it. At last the playing field has been leveled for me. The information contained herein is to me remarkable both for what it is and what it suggests in terms of further personal experimentation. I unequivocally recommend its purchase — David C. Hurd
Seven issues of the Journal of Guitar Acoustics were published between 1979 and 1982. These issues have now been republished as a single volume of 700+ pages, along with an updated bibliography and additional material. The complete index to the new JGA volume is printed below. The JGA volume is available for US$70 prepaid or via Priority Mail within the continental US, US$75 in Canada, and US$100 prepaid by bank check or money order only elsewhere, shipped via airmail (yes, international airmail costs us $30+). Checks should be made out to “Journal of Guitar Acoustics”. To order, send inquiries to:

Journal of Guitar Acoustics – Complete Unabridged Collection with Addenda
I. Dear Reader – Introduction, History and Summary
II. Tutorial on Guitar Acoustics
“The Secret Life of the Acoustic Guitar” (46 pages)
Course notes from a course given on guitar acoustics in the summer of 1978 to the recent graduates of a beginning guitar making course. This course, designed for non-scientists, introduces the major concepts and analytical methods essential to understanding how guitars make sounds (Structural Dynamics), how these sounds are transmitted (Acoustics), and how the human mind perceives these sounds as musical tones (Psychoacoustics).

– On Musical Instrument Wood – The first part of a two part summary of Dan Haines’ seminal work on the detailed physical properties of wood types commonly used in stringed instrument making. Precise measurements are provided for both modern and antique wood samples, plywood as well as the effects of varnish, lacquer, etc.
– Popular Attitudes Concerning Guitar Acoustics – A review of perceptions in the popular media.
– Recent Patents – First installment of a regular feature showing stringed instrument patents, ranging from the amusing to the bizarre, with occasional glimpses of true invention.
Issue #3 (June 1981) – Low Frequency Resonances (74 Pages)
– Observations – The first of a regular section on related tid-bits of acoustical delight from outside the field of stringed instruments.
– Interview with Daniel Haines – The acoustical researcher and inventor of the first accurate graphite based soundboard wood analogs reviews the development of graphite-epoxy composites, their application to stringed instruments, and the importance of keeping up with a daughter learning the violin.
– Identification of Guitar Resonances – The technique of producing Chladni patterns on instrument plates and completed instruments is spelled out, along with advice and historical context.
– On Modal Coupling in String Instrument Bodies – Guitar mechanics are visualized and explored with hologram interferometry.
On Musical Instrument Wood, Part Two – The continuation of Dan Haines’ seminal research on the physical properties of stringed instrument woods.
– Simple Model for Low Frequency Guitar Function – A detailed technical analysis of phase and frequency relationships in the guitar body’s most basic resonances is offered along with some remarkable derivations of various instrument properties.
– Recent Patents – Stringed instrument patents from January 1981 through March 1981.
Issue #4 (September 1981) – Puerto Rican Quatro (84 Pages)
– Translation of a Lecture by M. Lieppe – A 1977 presentation by a leading French researcher on stringed instruments whose formal investigations first bore fruit with the introduction of nylon to the manufacture of musical string-making technology.
– What is a Decibel? – A basic physical term is commonly misunderstood.
– The Puerto Rican Quatro – Bill Cumpiano introduces the reader to this soulful 8-stringed instrument indigenous to Puerto Rico, known for its exquisite sweetness of tone and simplicity of construction.
