>how music can be used in other subjects.<
By "other subjects" I assume you mean just Maths and Science, as they are the only subjects you have posted your message under. If you are interested in the application of music to, say, Modern Foreign Languages, I can make some suggestions, but I think I'll wait in the meantime until you express a definite interest in that combination.
