Answer:
Answer 1:
My sister plays piano and I play flute and I am pretty sure that flutes are a note higher than piano.So to convert it all you would have to do is play the song 1 lettered note higher.
Answer 2:
Find a flautist who's good at transposing music. The notes should be raised up one tone unless you want to take it to a different key and register. it's the same as converting bass to treble.
alternatively I use Sibelius 3 to transpose my music.
Answer 3:
The flute is not a transposing instrument, so transposition of the melody line is not necessary. All one has to do is take the main melody, usually identified in the treble stave of the piano music, and play it on the flute.
