Disclosure: I have never played this game. I'm sure everyone knows that 227 Bass Practice is the melody from the original LoZ's "Dungeon", while "Piano Practice" is from LoZ's menu/continue music. 228 Drum Practice is a rythmic version of "
Cave" from LttP.
Are 229 and 230 (same music) and their reiterations from something (other than MM) I'm not aware of?
