How do you slide harmonics?
To slide a harmonic, strike a harmonic on the 7th fret of the G string. This will give you a D that's an octave higher than if you fretted the same note. Without lifting your finger after striking the harmonic, quickly press down on the note while simultaneously sliding it down a fret to the 6th fret.
How do harmonic bass work?
Because the bass strings sound so low, the higher harmonics are much easier to hear. When you lightly touch a string at certain points and then strike it with your right hand, the string naturally produces harmonics. The strongest and clearest harmonics can be found at the 12th fret, the 7th fret, and the 5th fret.
