Baritone Ukulele Fretmeister playing and practice accessory- A brilliant yet simple learning aid that shows you, for any selected key, the 8 chords you can play, which notes you can use when writing melodies, riffs and licks, the root note & relative minor root note, blue notes, pentatonic scale and finger patterns to help you play using all of the fretboard. Also the minor pentatonic blues scale so you can learn to jam the blues in any key. Would make a great gift for any baritone Uke player
