Literature on Piano Acoustics and Synthesis
There has been much research into the musical acoustics of the piano, including models of piano strings [543,18,75,76,144,42] and the piano hammer [493,63,178,60,486,164,487]. Additionally, there has been considerable work to date on the problem of piano synthesis by digital waveguide methods [467,519,523,56,42].
A careful computational model of the piano, partially based on physical modeling and suitable for high-quality real-time sound synthesis, was developed by Bensa in the context of his thesis work . Related publications include [43,45,46].
An excellent simulation of the clavichord, also using the commuted waveguide synthesis technique, is described in . A detailed simulation of the harpsichord, along similar lines, but with some interesting new variations, may be found in .
The 2003 paper of Bank et al.  includes good summaries of prior research on elements of piano modeling such as efficient computational string models, loss-filter design, dispersion filter design, and soundboard models. A more recent paper in this area is .
