The first thing that I need to mention here is that once you have played through the lesson the first time and if you have played Alternate picking through the whole piece you will start over with the opposite type picking stroke. This means that if you started with a down stroke you will play the second time round with an up stroke. This certainly created a few challenges for me, but thats great, this means that you will improve you Alternate picking technique both starting with and up stroke and an down stroke. The piece is take from the piano maestro Frederik Chopin from he's 24 Etudes Op. 10. If you are new to Chopin you will definitively love him if you love Shred. Good luck
