Here are the "notes" you're trying to play:
ClearAll["Global`*"]
notes = Table[N[(440/64)*2^((n + 3)/12)], {n, 60, 72, 1}];
Table[Sin[# 2 Pi t] & /@ notes, {t, 0, .5}]
{{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}}
The entries are not real, the amplitudes are (Integer) zero, you're
playing 13 channels at once, and there's only one note.
I don't have a clue what the frequency or frequencies might be.
