Alrighty, if no one objects, I'll unveil my horrible horn playing.

Loosen up your jawbones, they'll be much cringing to be had.
I've been playing horn for a little over a year now, maybe 14 months or so... either way, I'm relatively new to it and brass in general, so bear with me.

Above: recorded today after a 3 hour practice session. I spent an hour on each trumpet, tuba, and horn before I hit "Record", so my lips weren't behaving too well, but well enough. First is my solo from To Challenge the Heavens and Sky, which we are doing in band. I took 3 takes, the last being horrendous. Then I played a two-octave C scale (concert F) then arpeggio, then tried a few lowish notes. Then I jabbed away at my only memorized excerpt from the Strauss horn concerto, a quick little bugger with some nasty jumps. Then I noticed I was running out of time and decided to plod my way through at tempo without stopping... you can see what happens by the end. I hate that last accented note, I always miss it.
Especially in the slow solo excerpt from the beginning, I noticed my pitch with REALLY unstable, this happens a lot with my slurred passages. Any advice?
Oh yeah, and you might notice the tone sounds a little choked...

I had to cover the bell a little bit because if I didn't it was too loud and it clipped on the mic and sounded horribly nasty. Recorded on my mom's laptop while she was out grocery shopping.
Oh, whoops, I forgot. I don't have a private teacher on any brass whatsoever. Self-taught. D=
Oh yeah, and the horn is a Holton beginner model because my school sucks. Yuck. I'm might be getting my hands on a slightly better Yamaha next year... (yay!) I've played on a Conn 8D, and I loved it, and my sound was a
little better so..... .....
Oop, and my mouthpiece is a Bach 11, it's my favourite out of three. Holton Farkas mouthpiece SUCKS.... my other is a Schilke, it's really deep (and really missing right now), the Bach is rather shallow and cup-shaped.
