## Description

FretBuzz CAGED System is a dedicated application designed to help guitar and bass players master scales and arpeggios using the proven CAGED system. It offers focused learning on individual "shapes" for a variety of musical structures including triads, seventh and sixth chords, pentatonic and blues scales, major scale modes, melodic and harmonic minor modes, bebop scales, diminished scales, and whole tone scales.

This app supports six-string guitars as well as four and five-string bass guitars, and features a left-handed mode to accommodate lefty players. Serving as an introductory volume to the more advanced "FretBuzz Augmented," it provides essential foundational knowledge for musicians looking to enhance their fretboard understanding and improvisation skills. Reach out to the developer for further questions or guidance on the CAGED system.
