This is a great composition by the Breton guitarist Soig Siberil. Like most of his work it is in DADGAD tuning and is a very clever use of open strings/ hammer on and pull off. Basically the right hand is plucking open strings while the left hammers the notes in between. At speed this produces an amazing avalanche of notes that is a lot easier to play than might first appear.
The trick in learning this piece is to get two different rhythmic patterns under the fingers. The first is the more basic- open strings and tapped notes- and should be started slowly and built up in tempo till the rhythm makes sense. The second is a little trickier and involves hammering on from a fretted note and then finishes with a pull off. Once you have these two patterns the bulk of the remaining work is memory and geometry. The same two patterns are applied in different places on the neck to generate the piece. It's great fun to play... .and if played correctly, it's not at all obvious even to fellow guitarists what's going on!
