The observed data allows us to conclude several things:
The main area of future development that we'd like to explore is a greater range of frequency measurement. We only examined the effect of the wood on the harmonics of the 440kHz note. If we could algorithmically examine other ranges, we could get a much better picture of a wood's potential as a guitar material.
A secondary area of development would be synthesis. If we can synthesize the effect a wood has on a sound, then a guitar could be built out of a cheaper wood and run through a filter that replicates the transfer function of an expensive hardwood. This would, no doubt, make us large amounts of money.
