Wow ! Have a look at this – if you are have no patience go straight to 2:35
Even on a normal acustic guitar, he does amazing stuff – it's on a very high technical level but it's clearly about music not technique… great!
If you like it, make sure to see his other videos too! His name is Andy Mckee.
Ten years ago or so, I also created a little guitar piece (but on a E-Guitar, much easier to play!) where I was also doing harmonic stuff with the right hand on the fretboard (tapping and sliding). I got the idea from a promo session with … ops, I forgot her name … she played with Michael Jackson on tour … ah, her name is Jennifer Batten. So on that promo tour for her solo CD and an effect machine, she did those slides with the right hand and so it inspired me to experiment with that. Slides are not so difficult but tapping a triad (accord of 3 notes) isn't that easy and for me doing this cleanly (without unwanted noise/notes) was always also a question of luck .. hehe 😉 Therefore seeing him doing this on an a-guitar, clean and with those percussion things … everything in a musical way … just WOW !
Today a played a bit guitar. Nowadays I am doing this unfortunately very, very rarely… the computer is now eating most of the time. But I'll soon see my little brother who started playing guitar too, so I need to warm up a bit 😉 I have this Epiphone 335 (?) copy with .11 strings (bigger than usual) on it and after a improvisation session on a backing-track my finger are hurting … especially string bendings were painful at the end … hmmm … just like in old times
