ah, sorry - part playing is where there are several strands of music going on at the same time, and (usually ) some notes are held while others move. Keeping this neat and clear is not the easiest thing to do.
Example - Kummer, bar 11.
First quaver in bar - four notes to play. Second quaver, upper RH note only moves; all other should hold.
Third quaver in bar - (from top) A moves to F, C still holding, G (LH) moves to A, E still holding.
Last quaver upper note in each hand holds, lower note in each hand moves. Ideally this needs to be virtually seamless, and certainly without gaps in the middle. It's quite easy to either loose something that needs to be held, or conversely to hold something that needs to give way. Fingering needs to be carefully worked out to make all this possible.
This all sounds rather clinical, and for sure the piece is much more than that, needing lots of shape and expression. But to make the most of the rich chords those held notes are vital - without them the harmony will be comparatively thin.
Hope this helps a bit, David.
Crikey!
Without the score, I think I know what you mean. I recall playing last night and thinking there were a few notes as you describe and that I really must have a think about how they should be played. It was the end of my session so I figured I'd take a look next time. I'll defintely re- read your note and examine the score. Come to think of it, I'll just print it right now....
Many thanks
