How Can I Extend My Coursework on Standing Waves?

[Faloren]

Ideas to extend my coursework? (Standing Waves)

Homework Statement

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.

Homework 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?
