We know how to play a normal glissando, but how do you play these glissandi?
a) Black keys glissando
b) Chromatic glissando
c) Thirds (or doubles) glissando
d) Octave glissando
How do you teaching fingering on the piano? Do you advocate a "fixed way" for fingering (as spelled out in the score, especially), or do you train learners to adopt a more flexible approach?
