Anyway I want to direct 2 questions at a specific piece. - Liszt Hungarian Rhapsody 2.
1) Has anyone tried writing their own and what criteria did you include so that you dont just write any old sets of flashy notes that aren't stylistic?
I did my own cadenza for the HR2. It pieced its way together in my head during my drives to/from work, born from me singing along with a recording of it in my car, harmonizing and hamming it up, humming counter-melodies and other oddities along with it.
If you're looking for ideas, try Godowsky --- he twisted and mirror-imaged the Chopin etudes so beautifully. Inverted LH patterns, inverted RH patterns, hands inverted, waltz, mazurka, polonaise...
Rach did similar things when creating his Paganini Variations --- the 14th and 15th variations are inversions of the main theme, with the famous 18th variation an advancement of the inversion. One can do similar things with themes from the HR2. The HR2 gives you so much to work with, given its structure and assortment of lines.
I liked my HR2 cadenza, although I haven't played it in 10+yrs. I never wrote it down, though, so I'd probably have to come up with something new now. I also had a "special" cadenza that I'd use for my non-classical music friends/family which slowly morphed into "Chopsticks" and other gag-me novelty pieces (kept in the style of Liszt, of course) that would crack them up and make Liszt roll in his grave.
