In front of you the world’s largest bible of guitar scales' concepts from Fonexsis. This is something without which it can not do any one musician. Conceptual Guitar (CG) introduces the most employed concepts of scales and modes.

«Concept» is a variety of repetitive sets of notes on each of the six strings. For example, the 3-3 concept implies use of 3 notes on each of six strings; 2-2 concept - 2 notes on each of six strings; 1-2-3 concept implies 1 note on sixth string, 2 notes on fifth string, 3 notes on fourth string, then 1 note on third string, 2 notes on second string and 3 notes on the first string.

In this app you can see the Scales that play overs certain Chord, and Chords, which play over a certain Scale. CG will be useful for both theoreticians and musicians of all directions (classic, jazz, rock, metal, pop, folk). Typically, a professional guitarist uses a number of concepts of performing scales and modes in his creativity. Thanks to this app you will be able to choose the concept that is right for you, because there are 60 (!!!) different scale concepts presented here.

All scales and modes are presented in diatonic, alt-diatonic and chromatic systems.
