Chemistry and Physics Handbook:
Velocity of sound: Brass                  3500 m/s
                   Wood (varies with species)
                    Ash (along fibers)    4670 m/s
                        (across rings)    1390 m/s
                    Beech (along fibers)  3340 m/s
                    Oak (along fiber)     3850 m/s
                    Maple (along fiber)   4110 m/s

for comparison:
                   Water                   1461 m/s
                   Air                      344 m/s

Therefore, I would assume that the *reason* for the differences has to do
with the density of the transmitting material -- more dense ==> faster
velocity.
