jazztabation 

When a jazz musician forgets he is playing to others and goes on a self indulgent jazz solo adventure.

It went on for 30 minutes, pure jazztabation.

Jazzturbation 

The mindless, meandering solo or song played by coffee-shop "jazz" acts. Especially referring to the solo bass player, trying to channel Jaco, with his 27 string bass and his $15 homemade CD with his goateed face on the cover, for sale at the counter.

Jane felt dirty with the gratuitous, self-indulgent jazzturbation going on right next to her in the coffee shop.

The act of aggressively masturbating to smooth jazz

Jim: Hey wanna go do some jazzurbation with me?
Bob: No Jim, that's gay as fuck

Jazzurbation 

To vehemently stroke yourself musically for the enjoyment of other musicians exclusively.

To much Jazzurbation and you'll go blind. And you'll be broke.
