Released in April 2020, the entire Bach Shapes book in bass clef, now with etudes also presented in Concert keys, so you can play along with videos or a sax player with the book. UPDATE 2021: New edition of the book, with new cover, and foreword by the great Lincoln Goines is available digitally and in print here and on Amazon.com. All of the exercises are written with electric bass range in mind, from E up to about B in the middle of the treble clef.
Scale/interval sequences taken straight from Bach’s Cello Suites, Violin Partitas, Inventions and more. Bass Clef edition also includes a few bonus pages of preview exercises from Bach Shapes Two, out later this year. More info, including articles, videos and testimonials at bachshapes.com
