I've come up with dozens of flute 'tunes' over the years, and now that I'm retired and have some time, with difficulty and clearly imperfect composition skills I've begun (five done so far) to reflect them as sheet music which is hopefully usable. Also I recorded them to give some idea what they sound like. Most are perhaps 'classical' - but some are more contemporary. All are, I suspect, of 'intermediate' difficulty.
