Quick Reference

Pf. invented 1921 by Moór. Has 2 manuals, the upper tuned an octave higher. These are placed so that the hand can easily move from one to the other or play on both together. Thus, scales in 10ths are played as scales in 3rds as on a normal pf. The manuals can be instantly coupled, so that scales in octaves can be played as scales in single notes.
