This piece is based on the piano improv of Ron (rolifer) (see "Piano Piece" posted 02-17-2008 ), with the original composer's permission. The story started on another site when I commented that the fine ideas in the improv might work well for a jazz combo. Ron suggested I have a try and posted the midi which I read into Finale.
The piano improv digressed into chromatic variations in the middle which I have deleted to keep it on the white keys, and to keep the piece to a reasonable length. A few changes were made to the piano part, some accidentals were removed in the closing section, but not many changes although going from midi to a Finale mus file can produce a few oddities. I added string bass, flute and clarinet parts to augment the original piano part.
On the title: all the notes in all parts lie on the white keys of the piano, hence "white" and "butterfly" because the piano part flits about and the piece is generally delicate and airy. When I finished the opening section, I thought of making a rondo - which turned out to be an ABACAD form. The A section seemed to have the feel of chocolate - one chocolate from the box is never enough. I added a light swing to the tempo as the string bass line seemed a bit lifeless with no swing.
The instruments are all GPO. The reverb is the K2 player's Recital Hall 2 setting with dry at +6db and wet at -10.3 dB. I wanted a crisp no-pedal jazz touch for the piano.
It was a risky experiment to try but once I got going the piece seemed to write itself over just a couple of days. I'm not sure what I was expecting to get when I started but I am quite happy with the result.
