Why Siemens? I assume you have a Siemens or Murray panel. If not, use the breakers recommended for your panel.
You do not need GFCI for a music room.
You many need an arc fault breaker if required by local building codes, if you are doing new construction or the panel is populated with AFI's.
Best bet: follow the advice of a licensed electrician.
