ALERT! REFERENCE MATERIAL POST!!! A 'voice leading and target tones' approach is more what we've been aiming for so far, but there are definitely ways to apply pentatonics to the jazz thing too. Don't think that you have to throw out everything you already know... you just have to start thinking about things a bit differently. Wes Montgomery combines both approaches in his playing so wonderfully. So do Kenny Burrell and Grant Green.
