My favorite tools: Pin Vise Voicing Tool


The December 2011 issue of the Piano Technicians Journal has a short explanation of this voicing technique in the Tools Tips and Techniques section of the magazine. It also contains a longer, feature article that provides more detail

Something is amiss.
Listen carefully.
Can you hear it?
What's the problem?

(Note: The problem may also be heard clearly on the CD as well as the original Stereo LP.)

About the Book
 
A study of the physics of the piano reveals that while the upper partials of the steel strings are the eigen-frequencies of the complex tone, they are not integer multiples of the respective fundamentals. To properly measure and tune these eigen-partials, a digital filter capable of sweeping a major portion of the audio-frequency spectrum had to be implemented. Such a filter, a tuneable fixed-coefficient digital filter, is discussed as well as a simple pole-zero design procedure for determining the required coefficients. Each module, including the frequency deviation detector and counter, the time-base generator, the digital filter, the reference frequency generator and the display and control module, of the proposed tuner is illustrated and discussed.
