There will be trouble, outrage, disdain, horror..
I never felt like messing around with Classical pieces anyways, I think the fun in them is to perform as close as possible to the original (or your) interpretation while, naturally, playing with your own "musicality".
In the baroque period the ability to improvise on a basic theme was compulsory. Pieces were sometimes not even necessarily written out in full, just structural, performers were expected to fill in the blanks with their own ideas - use their own ornamentation.. etc. etc.
Do you happen to know what caused improvisation to disappear completely from the world of classical music, despite arrangements (Horowitz on Liszt's HR No. 2, for instance)?Perhaps if improvisation would still be taught, we would all be better artists, don't you think?
You can do it as much as you like, and it's actually probably good for you.One caveat, though. In the "classical world" if you say you are going to perform a particular piece, the audience will expect it to be stricltly in line with the written score.
Only in competitions and auditions you're supposed to play strictly to the score.

Many romantic era composers also improvised all the time.My explanation to the disappearance of improvisation from the classical piano playing is that after the 19th century players were not composers anymore. So they didn't really need the skills and it disappeared. Other things took over (playing technically perfect and excatly as it's written). And after a while the audiences and critics started expecting this too.
