FretBuzz is an application for learning scales and arpeggios on guitar and bass guitar. It is focused on CAGED system and learning individual "shapes" for all the below listed arpeggios and scales. Triads Seventh and Sixth Chords Pentatonic Scales Blues Scales Major Scale Modes Melodic Minor Scale Modes Harmonic Minor Scale Modes Bebop Scales Diminished Scales Whole Tone Scales The application has a lefty option for left handed guitar and bass players. The application has support for six string guitar, four string bass guitar and five string bass guitar. This application is like a Volume I to my application "FretBuzz Augmented" which utilizes scales and arpeggios in common jazz progressions. For further questions about this application or about CAGED system you can contact me via my developer account. Thank you.
