Book excerpt: (Book). The Responsive Guitar is about physics, dynamics, acoustics and construction of the guitar. It's about the mechanics of tone; what materials to build with, when to add or remove wood for maximum benefit, and why those techniques work. Somogyi explains in exquisite detail how the guitar makes sound, and what musicians and luthiers need to know in order to appreciate a really well-made guitar. This book sets the foundation for the matching volume Making the Responsive Guitar .
