Oh, do we ever! Happens all the time. But it all depends on the circumstances and what's going on when this happens. LIke, if it's Bach, it probably means the music was intended for a two keyboard harpsichord and you give priority to one of the voices. Or if it's from the romantic repertoire, the composer wasn't bothering with insignificant details like that, and you worked it out with appropriate pedaling. Just what music are you referring to?
Scriabin Etude Op 8 No 12. On the 1.st page, there are all over that kind of examples. Left hand is important, so dont know, if I execute or not that kind of tones.
NO! If we're talking about the same passage - it happens first in the 2nd full measure. The right hand plays a triad of e# - a#- e#. On the second beat, in the left hand, the second eighth note is a repetition of the a# the r.h. played before. play it and forget about it. There's tons of pedal and the right hand repeat the a# in the next two chords. This is just an example. Some pianists might play that second a# with the r.h. to avoid the enormous stretch in the left hand. I don't understand why you would want to hold that a# down just because it's represented by a half note. The pedal sustains it.All this, of course, IF we're talking about the same place.
