Underlying tonality changes to A minor for the first time

25
Q

How is the piano part in bars 104-111 constructed?

A

Bass line expanded from single notes to pairs of 5ths rising up through the tritone A-C-Eb (A-Eb being the tritone)

Seventh chord on C in first inversion in RH

26
Q

Describe the piano part in bars 112-142

A-C-Eb bass continues

Harmony predominantly confined to C7 and Eb7
