Word for "to make music"

I'm looking for a word that means "to make music" without regard to how the music is made (vocal or instrumental), like "to sing" means to make music by passing air over the vocal chords.

Example sentences:

I am going to ____.

Let's ____.

I would like it to not require an object( for example "play" would work, but the meaning is unclear without stating what is being played).

EDIT: To clarify, I am looking for a single word meaning to play music, not a word meaning to write music, although it should be able to apply to improvising(playing and composing music simultaneously).

EDIT2: "Make Music" does not work because it is unclear (it could mean to compose or to play music) and sounds too formal for common use.

Solution 1:

jam (intransitive verb)

Wiktionary.com

6. (music) To play music (especially improvisation as a group, or an informal unrehearsed session)

"I'm going to be jamming tomorrow so don't bother me."

spiel (intransitive verb)

Merriam-Webster

1 : to play music

perform (intransitive verb)

dictionary.com

11. to perform (carry out, execute, render) music.

Solution 2:

In Hamlet, Ophelia declares, "And I, of ladies most deject and wretched, that sucked the honey of his musicked vows" (Act 3, Scene 1, Lines 158-159). If "musicked"--ergo the verb "to music"--was good enough for Shakespeare...

Aside from that, I know of no such word other than those you mentioned. English verbs are more specific. They all refer specifically to how the music is being made.
