Does anyone else here ever implement fast passages into their songs that are much unlike the rest of the composition itself, I.E. a Cadenza passage or "Flourish", often full of quick arpeggiations?

I seem to use this effect quite often to generate a new wave of interest for the listener, or to just make the song a bit more unpredictable yet expressive.

Am I alone in doing this?

I also find Cadenza passages helpful in transposing the piece to another key.

It is also very useful in order to prepare the listener for a Picardy Third, methinks.

Hmm, can you please provide a particular example? ^^

Examples can be found in both The Moonlight Sonata (1st mvt.) and Fur Elise by Beethoven. I'm referring to the uncharacteristic, seemingly abrupt quick passages (the "fatasy" part in Moonlight, involving 7th chord arpeggiations, to be exact, which is often sped up).

Oh!!

For me, I never did like that fast part near the end of Fur Elise . . well it was nice to play and everything, but it didn't fit the piece in my opinion. So er, I guess I'm opposed to "uncharacteristic, seemingly abrupt quick passages" . . . in this particular case though . . then again, I generally prefer gradual transitions. But that's just me . .

Für Elise without those fast parts would be kinda boring :huh: just the same thingy over and over again =_=
