I have just finished writing this, have been composing this on and off since last summer.
I haven't even learnt it properly yet, this is something like what it should sound, at least all the notes are there.
Definitely not an easy piece and I will work on it in preparation for my October recitals - this will be the encore, or possibly the last piece on every program, printed.
don't judge the playing too much heh.
I basically stuck to the original layout of the Waltz, all the repeats with textural variations, contrapuntal combinations of themes, and developing of small motives derived from the themes - throughout. (I mean, it's an homage to Godowsky).
In case you don't know the Waltz: here is a recording of the original orchestral work. Note that I replaced the original introduction with my own.
