This is a great learning tool for beginning and intermediate 5 string bass players. The 11" x 17" instructional guide is nice to hang on the wall wherever you practice for easy reference, instead of flipping through a book. This chart includes the notes of the bass displayed on the fretboard. The chart also includes the Nashville Numbering Chart and Cirlcle of Fifths. This information can be found in books, but rarely on one easy to read chart! Made in the USA
