Barret Articulation Studies in Keys

These are the famous set of the 12  Barret Articulation Studies in a variety of keys.  They make for good practicing.  Several of the studies are reprinted in parallel keys (i.e. C# and Db).  

Study # 1

Study # 4

Study # 2

Study # 5

Study # 3

This has been a massive undertaking. There may still be some improvements needed.  Please feel free to offer suggestions.
