Is your feature request related to a problem? Please describe.
If I'm playing alone I can't play more than 3 instruments at a time.

Describe the solution you'd like
A block that, when powered by redstone, plays the instrument it is holding (item instruments) or the instrument in front of it (block instruments).

Describe alternatives you've considered
Allowing mobs that are holding instruments to respond to received notes. But not easy to give specific items to mobs and wouldn't work well for block instruments unless I made them sit at it.

Additional context
N/A
