How do you play a tremolo attached to a stack of notes on a piano? (Is that the right wording?) I put an example below.
I've seen this sort of pattern several times in piano arrangements of popular music. Does it mean that I should repeat 32nd notes for the duration of a half-note (minim) as in the image below? That seems unreasonably fast to me.
Should I break it up like this?
Any help would be appreciated.
