When I did a college performance, I played about 1 page of a 4 page piece which is about 20-30 secs and they said stop, and accepted me. Get a couple pieces together just incase though, as they may ask you to play more than one. I dunno how good you are on the guitar, but Johnny B Goode all the way, its not particularly that hard, and if you got the right technique you can have any1 tappin there feet, and noddin there head to that, only problem is once it gets to the verses, its a fairly repetitive chord sequence without much articulation, but if you sing during this time, u'll have em drooling man I got a shitload of Jimi Hendrix tabs aswell, if u want em, u can hav em, jus drop me ure Hotmail if u got msn.

And yeh performance anxiety is a bitch (Sounds like a case of Mr. Floppy when put that way), but everybody suffers with it, and the key is to not be too rigid (especially as this is for a music performance course, and not a board of music exam), chances are if you try to giv a mind blowin performance, it will turn out shit, because u are too technically aware, and ure movements become rigid, ure too bothered with dropping the notes at the exact right moments, and forget what the piece is, a piece that flows together, when you talk you don't articulate every sound of every letter in the word, you don't even think of words, you just correspond the thought, and ure mood towards it to the sounds ure puttin together, and the sentence appears as a rollercoaster of tones and sounds. When I play any instrument, my mind turns to jelly, learn the piece like the back of ure hand, and let ure fingers correspond directly to where you want the sound to go, before you know it ure gaze is fixed str8 ahead on nothing in particular, and ure starin at ure sporadically moving fingers like they're not ures.

And gettin stoned could go either way, you may zone out completely on the piece, or you could be consumed totally with the fact there is sum1 watching ure every move, but remember this is just for a music performance course, they don't expect virtuoso's, jus sum1 they see fit enough to play in time, and has the artistic ability to write a few songs come coursework submission time, so whatever you learn, make sure u r comfortable playing it.

So loosen up man! its not the end of the world if a couple of teachers think ure shit, who gives a fuck, they're a couple of teachers, for one college
