Tips
- For the barre, keep your index finger close to the fret and slightly rolled onto its bony side; thumb behind the neck, around the middle.
- Pick each string on its own and listen for muted strings; a finger touching the next string is the usual cause.
- Press, release, press again: if you can form Bb7 cleanly 20 times in a minute, you have it.
