Ideas to extend my coursework? (Standing Waves)

1. The problem statement, all variables and given/known data
I'm doing some coursework for school at the moment, and my chosen topic (because it was fun first time round) is standing waves on some kind of wire/string - ie vibration generator, wire and fixed end (ie pulley) with mass dangling off the end to produce tension.

2. Relevant equations

$$v = \sqrt{T/ \mu}$$

Basically, at the moment i've got data for a few different types of wire, held at different tensions. The data is harmonic frequencies - ie watching the string until a standing wave is produced, noting the frequency as the signal generator shows, etc. The plan is to the use the data to verify the equation above (substituting v for $$f\lambda$$).

This is all well and good, but could you possibly suggest a way of extending the experiment - say something to do with musical instruments "what material would be most suitable for such and such a stringed instrument's X string?" or whatever would work :)

Thanks!

Do you have a good microphone and some sort of math analysis program that can do Fast Fourier Transforms?
