What kind of sheet music should I use to compose songs?

I've just been using piano sheet music to compose my song and I am wandering if that is the right chose or if I should use a diff. instrument to compose the songs. And I have been trying to compose the acumpentament(sp?) but sometimes there are like 5 notes in the same spot so how do I compose those.

Thank you.

There's really no way to do a verbatim adaptation from either a recording or sheet music. Any sheet music—piano reduction, guitar tab, or full orchestral score—can be a good starting point for a Leaf Trombone music box accompaniment. However, in order for it to be really effective, you need to learn how to reduce it down to its barest essentials while not making it sound too spare. A music theory background helps, but it's not necessary.

When you have an accompaniment written in chords ("5 notes in the same spot"), one common solution is to arpeggiate it. Study the accompaniments of songs you think are effective in the Leaf Trombone library, and see how other composers find creative solutions to the "single-unsustained-staccato-note" problem.
