Xylophone & Other Barred Percussion is now available in iBooks and Kindle formats, in addition to the color print edition. You get the same 44 lessons, complete with zoom-enabled scores, and working links from one part of the book to another.
(Due to Amazon royalty contracts, the Kindle version has been split into two volumes. Notice that this is still an incredible discount compared to the print edition.)
Kindle Edition, Part I: $8.49
Kindle Edition, Part II: $8.49
