Very clear question:
HOW to make a piano reduction with multiple voices and rhythms ?
Like a reduction of a string quartet poliphonic material with 4 voices:
ALL RHTYHMS INDEPENDENT with their own pauses.
With the typical arrangement of stems for voice separation:
TREBLE CLEF - voice 1 stems up
TREBLE CLEF - voice 2 stems down
BASS CLEF - voice 3 stems up
BASS CLEF - voice 4 stems down
Any help ?
