Early is on time. On time is late. Too many musicians shoot their careers by not dressing thepart and showing up late. Check at your school for that. Follow their rules,and you will be working.
Adaptability is key.
A great way to get work is to give work. People will call you for work when they know that you have work to give. People want musicians who can lead ajob, run the show, get the people to the gig on time, etc. There is a great debate as to if it's wise to directly contactBroadway players in an effort to sub for them. Most veterans alreadyhave lengthy sub lists, so it's really a crapshoot.
