Man you can lead up with a few notes or whatever like u hear in that example I posted. Im no pro at It ive only done it in a beat once and it was an accident lol though I dont contribute anything to luck.
And then theres the example I posted. And just practice on the keys. Im proabably right around the same stage as you with the theory.
But yeah for real BC is normally on this stuff maybe hes away/busy or something. Either way he responds to PM's he loves helpin with the theory.
