Watch the Melodic Harmonics online guitar lesson by Jennifer Batten from Rock Sauce For Lead Guitar

A pedal-less way to get the effect of sliding in and out of harmonics, would be to tap the melody an octave higher than the left hand melody fingering. That way you can bend notes in your left hand while getting harmonics in your right hand. This method also does not restrict you from getting any notes in the chromatic scale in any key, as natural harmonics do.
