How to make Perform macros(?)

[MOZZYSTAR]

Yo!
So, I tried to make macros as I would with regular actions but it didn't work. Someone else mentioned using Python but I'm not quite sure how that works. I wanted to try playing some FF8 tunes on my harp. B) Anyone get how to do this?

So far, I've tried:

/ac "note"
/action "note"
/soundeffects "note" (because its volume is controlled by se)
/ambientsounds "note" (desperation)
Et cetera
