I'm all about the slap, tap, harmonics, tapped harmonics, etc. etc., but for the life of me I just simply can not find a use for sliding harmonics. I can slide three notes at a time with my left hand and even slide pinch harmonics that are done over the fretboard (obviously not ones that are above the 24th fret). By their nature they seem to be a kind of technique that one would use as a subtle accent to a larger line, but I've never even heard one used other than my teacher showing me the technique, and I've never heard them used in any sort of actual musical way. How about y'all? Ever had a technique that you just can't use?
