You want to get realistic with horn and wind emulation? Sing along with your solo! When you run out of breath, stop playing. Don't start until after your breath.

You might also take a stab at learning to play what you are singing. Most of us can scat a decent solo under our breath, so to speak. OK, you may not get the pitch dead on with your singing, but I bet you it's a dozen times more naturally flowing than a simply PLAYED solo. Our voices are the only instrument we have directly wired into our brains. Everything else is second hand, but the voice is the window into the soul. We all dream about those mythical 'brainwave to MIDI' converters, but here is one you already have!

Practice scatting a bar or two, then try to play what you scatted. Keep it simple. Work it up to more and more bars, more and more complexity. Then try doing BOTH at the same time. Start simple, work your way up.

Pretty soon, you are playing expressive, natural sounding solos that would make a horn player proud!
