Walk into the room that you will be playing saxophone in. By now you should know how to play at least at a beginner level.
Step2
Once inside your gig-room, start bragging about all the bands and places you've played in. Talk about how much you study Charlie Parker's solos and music.
Step3
Play as many notes as possible. Grunt, hollar, scream, make any other noises you feel you can make. Continue to say "that's baby makin music right there!" Stomp on whatever you can find.
Step4
At the end of the gig, walk off and say how amazing that solo was and how much everyone enjoyed it. Never loose the cocky arrogant attitude.
Tips & Warnings
Get paid in advance, dont wait til after the gig.
The best time to leave is when people start throwing things at you.
