## What is Conceptual Guitar Chord?

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.

### 5/5 — Really cool app!

*2024-09-14*

The concepts of scales and chords allow you to choose the right fingering for different hand sizes. This is an important feature for beginners. The program is not cheap, but it's worth it! There are many guitar videos on scales and chords, but here there are much more than in any educational video, and everyone can find something special for improvisation. The function showing which chords fit the scale and which scales fit the chords is well implemented. Perfect for teachers like myself!

**Developer response:** "Happy to help! Good luck to you in such a challenging task as teaching! With respect - Fonexsis team"

### 5/5 — I found what I’ve been looking for!!!

*2024-09-08*

Finally. I’ve found exactly what I’ve been looking for! This app has everything I wanted – modes with concepts for 2, 3, 4, and more notes per string, and most importantly, the chords that fit them! It features an advanced system for determining modes, allowing you to play over a II-V-I progression with just one scale or mode. In short, I highly recommend this app, it's the best I've seen in the App Store and even among paper books, and I have a lot of them. (By a lot - I mean really lot!!!)

**Developer response:** God bless you and good luck!

### 5/5 — Do you want to level up? Then download!

*2024-06-29*

Wow, what a find! This app is just amazing! The lessons are so interesting and easy to understand, I didn't expect such quality. Highly recommend it to anyone looking to explore a new direction without the headache!

**Developer response:** Best regards - Fonexsis team!

### 3/5 — vieillot

*2022-09-06*

concept sympa dans une interface d’un autre âge 

il y a eu une mise à jour sur ce produit de ce développeur c’est cher il faut attendre les promos quelle durée de vie ? 

fait ce qui est dit mais pas assez souplement quand aux noms de certaines gammes je suis dubitatif 

 on a nos habitudes et cela ne fait pas de mal d’avoir des autres idées que l’on ne voyait pas ceci dit on a des possibilités et comme l’on fait on a nos bases et on introduira des bouts de gammes dans notre répertoire passer de gammes a accord chacun sa façon ça n’est pas le sujet.

  on aimerai avoir aussi une vue d’ensemble car étaler une gamme c’est une façon courante 

conclusion interface désuète, on a les correspondances, des noms de gamme assez exotiques surtout très cher

suite à la réponse du développeur j’avais fait mes propres recherches sans que cela ne me coûte de l’argent 

quand à l’interface elle est désuète et peut être ne voulez vous pas investir car vos produits ne semble pas se vendre suffisamment 

j’ai fait quelques suggestions pour ne pas être que critique 

vos conseils sont intéressants ceci dit je ne les appliquerai pas

**Developer response:** Cher utilisateur, restez simple. Traitez-le comme rétro, car le contenu est beaucoup plus cher que l'interface ! Le travail sur le programme a duré plus de 2 ans ! Les recherches les plus sérieuses ont été faites sur toutes sortes de sources, y compris les cultures asiatiques et orientales ! La dernière mise à jour est publiée uniquement avec l'autorisation d'Apple. La prochaine fois, soyez plus prudent, car les liens de démonstration vidéo youtube sont joints dans la description et sur le site Web fonexsis.com/ Merci d'être avec nous !

### 4/5 — level numbers

*2021-06-30*

hello! is it possible to add a possibility to show a level number on cursor display?

### 5/5 — NOTICE!

*2019-05-14*

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.

### 5/5 — Nice App

*2018-08-25*

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.

### 5/5 — Love it

*2018-02-13*

Terrific app and I'm pleased that AI bought it.
It has everything that you will need, accompaniment and a metronome are built in 
that will help you all the way.
Everything one needs to get you quickly up and running at your own pace 
Awesome app with great graphics

### 5/5 — WOW!

*2016-10-02*

Another great contribution to the world of guitar instruction from Fonexsis.
