I had this idea last night... Basically, we all contribute short jazz lines that we've either transcribed from CDs or developed ourselves. Hopefully after a while we'll have an big resource for lines you can use over all the typical jazz sequences (2-5s, 5-1s, 2-5-1s, 3-6-2-5-1s, 1-6-2-5-1s, Coltrane changes, chromatic descents, 12-bar, turnarounds, etc.). I'm not sure what the copyright laws are for things like this, so it may be best to just say who you got the lick from, rather than what specific recording you transcribed it from... I'll go first... Here's a Charlie Parker lick I transcribed last night that's played over a V7-I7 set of changes, although it would also work over a normal V7-I.
