I am new to the whistle, and have bought a D whistle. I have a fingering chart and am ready to find some music. Couldn't I just use fiddle tunes that are in D or G?

What are the old standard tunes one learns on the whistle?

Do any of you have any favorite books? (Hopefully available on the 'net, since I don't get out often.)

Many thanks for any help,

Margarita
