I might have a guitar or a piano on set to play something for the actors.

I play piano and trumpet. I studied classical guitar.

I play guitar, piano, bass and percussion.

In discussing the process with the actors, I made it clear to them that they could improvise but that the sum total of their improvisation needed to impart certain plot points, and schematic material.

I like to play the ukulele, but I'm not, like, awesome at it. I mostly play the piano and the guitar.

If you can't play it on an acoustic guitar or a grand piano then it's not a song.
