附注:
The tuning is open-G lowered two whole steps to
Bb Eb Bb Eb G Bb (bass to treble).
After you have learned the piece you may prefer not
to tune all the way down to Leo's pitch. In that case,
use open-G tuning : D G D G B D (bass to treble).
In most measures the thumb must pick the third-string
note on the third beat to ensure a strong
high-octave note.
