Explore world's largest bible of guitar scales and concepts. Find scales that fit certain chords and vice versa.

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.

This is not a review to slander this app or its developer. Rather I believe I have a duty to anyone else wondering if they should make this purchase. This is a very good app and I once considered it one of my best purchases {and hope that it will be again}. But I was recently made aware that these apps are no longer supported by the developer. In his own words: “currently we cannot afford more people to support our older apps and develop updates for them.” (This app and Quartal Harmony open upside down on the latest iPad Pro) These apps are only worth high prices when they work fluidly and are supported and updated regularly. This is written as a guide to future purchasers and as a plea to the developer to make the sacrifice to satisfy the customers who have made the sacrifice to support these apps. Thank you.

Developer Response ,

Thanks for your review. We have already prepared a new update to fix these issues and tried to submit it to App Store. However, Apple review team has rejected our update and prohibited any further updates of this app. Instead, they have proposed us to combine a number of our guitar apps into one single container app, called "Guitar Driller", which is free for download, with internal in-app purchases. We plan to combine most of our existing guitar apps into Guitar Driller in the future. You can download Guitar Driller app now for free on the App Store. Thanks for understanding.

Nice App

But for the cost I am disappointed; no lefty view. I’m a left handed guitar player, please do an update and show the left hand view of the scales. Otherwise a great app. Kenneth Parker’s view.
