Wood Species	Use	Velocity of Sound	Fundamental Tone	Harmonic Overtones	Stiffness	Weight	Description
Sitka Spruce	soundboard	high	strong	mod weak	high	low	robust, meaty tone - strong treble, good headroom, clear tones; can sound thin when played at low volume.
German spruce	soundboard	high	mod weak	strong	high	low	bright, full complex - quicker response than englemann, fullness at the lower end; expensive, difficult to obtain high quality boards.
Englemann Spruce	soundboard	high	mod weak	strong	mod high	low	bright, full rich complex tones at low to moderate volume; sound can break down at high volumes
Red Spruce	soundboard	very high	strong	strong	very high	mod low	rich, full, complex, clarity at high volume; expensive, difficult to obtain appearance grade tops
Red Cedar	soundboard	high	moderate	strong	mod high	very low	dark, warm, quick response, enhanced lower end; sound can break down at high volumes
Mahogany	soundboard, back and sides, neck	mod high	moderate	mod strong	moderate	moderate	strong, punchy, crisp, dry tone, with a typically strong midrange
Maple	soundboard, back and sides, neck	low	strong	weak	moderate	moderate high	smooth response, acoustically transparent, good for recording and high amplification; can flat and tonal.
The Rosewoods	back and sides, fingerboard, bridge	very high	very strong	strong	very high	very high	dark, warm, full, complex - has the lowest resonating frequencies of any wood, complex bottom end with slow decay of sound; expensive, endangered, can sound "reverby" sympathetic vibrations may cause muddiness, a problem for recording.
Ebony	fingerboard. bridge	very low	strong	weak	high	very high	highest internal damping, does not color the sound and can quiet unwanted overtones; expensive, endangered.
Spanish Cedar	neck	mod high	moderate	moderate strong	moderate	mod low	similar qualities as mahogany, lighter, slightly quicker response and not as strong structurally.
