My daughter has to compose a dance to a piece of music that she chosen.

The dance is only 1 and a half minutes long. So she has to take 1 and a half minutes of the tune that matches exactly to the dance.

Neither of us know how to edit a song or tune to get exactly what part is required.

Does anybody know of a free piece of software that would allow her to cut the part out that she requires and is simple to use.

Many thanks
Les
