that is a cool way at approaching each Instrument including the vocal run he did. or Billie Jean:now breaking down the Drums, to the Bass or the Synth parts&then the guitar riffs. breaking down parts helps you understand what builds a Band or Act to a certain formula that they live by. take Earth,wind&Fire for instance: there basic Rhythm Tracks never truly changed that much.there might be a Kalmiba solo here or there,Keyboard solo or Guitar solo or a Horn Solo,but the basic tracks never changed that much. you could follow that&Play behind that Bridge or stay on that Bottom through out. but you can do that with any artist. that is how I got hip to knowing a Artists work without even hearing the full song?? there is Signatures,Tones,&certain runs that you just know. that is what helped me a great deal&still does.from Motown grooves through Timberland Grooves you can pinpoint certain things. a crafty Musician can bridge those sounds&tones.
