Not rolling chords

[roncesvalles]

I've been learning a few pieces by Sabaneyev lately, and in several places there are indications to arpeggiate either chords or the notes of multiple voices (that sound from a single hand).  As far as I can tell, these arpeggiations are designed primarily for a performer's ease, since texturally they stand apart from most of the rest of the respective works.   

My question is this:  is it ok to not arpeggiate (despite the score's indication) when the notes either fall comfortably to my own hand span or can easily be taken by the other hand?  It's the opposite situation than the common tactic of rolling chords when there is no indication to roll, simply for the hand's sake.  To me, it sounds better, more consistent, to not roll here, but I feel hesitant to blatantly disregard markings on the scores, which are otherwise fairly meticulous.

For artistic effect, do what you want. For a competition or classroom grade, do what the score says. Unless you can find a better score. The internet is wonderful, go looking for the manuscript or something.  See if your suspicions are correct, that the printer put the rolls in so that the piece would sell better.

I'd argue to do whatever you want in private or competition/classroom. However, it's extremely important to actually try both methods to compare the musicality and voicing (by recording and playback). Music is an art like any other; interpretation is up to you. That being said, be mindful of who may be judging. Some pianists are too rigid to accept music as an art instead of a science and will be disgusted by anything that is not a direct repetition of other performances.

For what it's worth, one of the greatest performers (Liszt) did whatever he damn well pleased with everyone's music. But... He was also Liszt...
