You roll it. Frankly, if you didn't already know that are you sure you should be trying to play this piece?
a better alternative could possibly be to play the bass alone and then the rest of the chord in one.
not necessarily. a better alternative could possibly be to play the bass alone and then the rest I'm equally bemused though. I have no idea how anyone could seriously have reached the level to attempt such a transcription while having to ask what to do if you can't reach a chord.
You're not very bold. I'm practicing stuff years past what my teacher had me doing 45 years ago. Are you afraid to practice without a guide? I think rolling chords on pieces that orchestras play all together sounds bad. I'm practicing Pictures at an Exhibition, and the Chicago Symphony under Fritz Reiner doesn't roll chords. So I don't. Some chords I put an interior note in instead of the long reach one. Some chords I play the low note with my foot. I'm not Russian, I don't have that kind of reach, but that doesn't mean I have to play the native six hole wood flute.
