pose them just above the frets....don't press down...keep em low and steady. Play your scale, arppegeio or lick ...It really teaches your fingers to not rely on This is a cool technique to get your fingers to OBEY you! The MASTER. hehe
Oh yeah...when you do get your fingers back on the board, play correctly always! Remember practice does make perfect and playing it wrong only reinforces your muscles to make mistakes!
Enjoy!
