I'm auditioning for the UNT jazz studies program in March, and was hoping to find some experience on this here board I can draw from. They have an option for a taped or live audition, and I can make it there for the live. Seems like the better option, but I don't really know. I'm also wondering how tough this can really be, I've been playing in jazz bands since high school, but here's the breakdown for the taped audition: "We request that you submit a video (DVD). Your audition video should be no longer than 15 or 20 minutes. It should contain a minimum of five samples of your playing in various styles: 1) medium tempo standard, 2) jazz blues, 3) jazz ballad, 4) fusion, Latin or funk, and 5) up-tempo standard or rhythm changes. The medium tempo standard and jazz blues should include both a walking bass line and a solo. The others may also contain a solo. All selections should show your ability to function in a rhythm section." None of that sounds that bad to me. Anyway, any advice, etc. will help. Thanks.

sounds like the standard audition to me.
Advice:
stay away from the overplayed jazz tunes.
Don't solo unless you have something to say- they will know right away if you are "playing scales". Do not overplay or attempt to impress them with chops. they gets lots of that already.
If you record, show them you can play on the beat and behind the beat. Don't rush.
if you can, in one of you solos, "quote" another bass player (preferably one who was a pioneer) or play a melody that is not the one of the song you are playing. Not a long quote- just a enough to get the idea across. if you do this live, watch the board's reaction- the ones that "get it" are the ones that know their stuff and are paying attention to what your are playing. (when i auditioned, I did this out of fun, and my future bass teacher cracked up when I did it- my future improv teacher cracked a smile, the head of the board didn't even catch it, so I learned right away who my allies would be.)
Choose the tunes to fit your musical personality- if you present to them a clear musically mature identity, this could put you ahead of the pack.
In music school, your first goal is to be in the top bracket when you hit the door- one step ahead of everyone else. Your second goal is to make your connections and try to work with the instructors- you will learn a lot more that way. Your third goal is to learn. Then develop your musical identity to the point where, if someone hears a recording, they can name you from what you play.
