Galloup Wood Management System

Sound Systems for Tone Woods

Bryan’s Tone Wood Library is one of the most prestigious private collections in the lutherie world that is ultimately the culmination of his tone wood testing and rating system. He developed this approach to identify woods unique musical properties to produce the finest sounding and most reliable musical instruments in the world.    

How the rating system works

It is not a grading system offering a numerical or alphabetic assignment that defines the quality of the tone woods. Our rating approach isolates sonic value and structural integrity giving you the power of control over woods variations and ultimately the sound and longevity of your musical instruments. But it goes much deeper than that, we offer application and stiffness values for calculating thicknesses and identifying woods application possibilities. The Galloup Rating is far stronger than the calculation of “Q” and the bottom line is; science is a powerful tool and the Galloup System is the most advanced system in tone wood science.

Galloup Rated sound boards are available to all Galloup School graduates and are used for Bryan’s Tone Development classes. Additionally, Bryan offers a tone wood rating service to our friends in the Luthier community. For more information contact us at: or 1-800-278-0089
