(Music Sales America). Since their introduction, Bach's Two-Part Inventions have been an essential resource for developing hand independence and ornamentation technique. Keyboard players have enjoyed these etudes for centuries and now this body of work is available to guitarists in this collection of fifteen pieces. They have been transcribed and arranged for the classical guitar duet by Jerry Willard, and are presented in notation and tab. The title is accompanied by two CDs, the first of which features demonstration recordings of all inventions. The second CD offers single guitar recordings so you can play along.
