Chord! - Guitar Songbook, Chords and Scales

By Thomas Grapperon

Open iTunes to buy and download apps.


Chord! is your next songbook, chords and scales app for guitar or any fretted instrument like bass, ukulele, banjo, etc.

With Chord!, you can write a song by simply dragging and dropping chords, transpose it in any key, compute the fingerings with any tuning and generate a beautiful print-ready PDF, etc.
You can also import your existing songs in text format (please note that the app does not ship with songs).

Unlike other chord charts app, the app doesn't rely on a database of charts. Instead, it computes and analyses all the possible fingerings.
You don't even have to know music theory to use it: behind its brute force, the app knows how to handle by itself some subtleties of music in order to give meaningful results.

If you don't have to be an advanced player to use the app, you can however take a look under the hood and tweak the parameters if you like! Whatever is your level or your instrument, Chord! will adapt and give you the most precise answer.

You can search for practically any chord, split (like D/F#) or not. If you're a beginner, you can choose the chord from a list, but you can also use the intelligent keyboard to enter the chord as it is written. If this keyboard is a great way to enter chords, it is also very useful to discover and understand how the chords are formed. You can also enter some notes on a neck to find which chords it can be. You can hear how each fingering sounds.

Chords are not all and the app is also shipped with the biggest list of named scales. It analyses and presents them with nice interactive views (scale, score and keyboard). Of course it can also lay down these scales on a neck (with sound). Like for chords, you can even search for a scale from its fingering!

Each scale can be harmonized (decomposed into chords). You can also enter a sequence of chords to find which scale you can use to improvise onto.

You can use one of the hundred tunings shipped with the app, or you can add you own ones, for any instrument, with or without a capo, even with broken strings if you want!

The app uses custom and unique algorithms to generate charts, easily input complex harmonic structures, extract chords from fingerings, determine fingers positions, compute keys of scales, generate chords from scales and find scales that go well with some chords.

For example, Chord! is the right tool in these situations:
• You want to have your songbook available at any time, in your pocket;
• You're a beginner and you want to know how to play easily a D/F# chord;
• One gave you an ukulele and you want to know how to tune it and how to play the G Hawaiian scale;
• You want to know on what scale you can improvise for some chord sequence (and the answer can be different than the Pentatonic minor!);
• You want to print your song and share it with your band.
• You want to experiment this nice open tuning, moreover with a bottleneck;
• Your little sister can't make bar chords and you want to show her how she can do without bars, with three (little) fingers only;
• You want to impress your little sister by showing her how you can play the same chords with two bars!
• You want to understand how this fingering for C13 is actually a fingering for C13;
• You broke a string and want to know how to play some chords without;
• You want to know how Django managed to play with two and a half fingers.

The app fully support left-handed instruments.

Main functions of the app:
- Write, transpose, fingerize, print and share songs;
- Search chord fingerings (or chord charts);
- Search chords from fingerings;
- Search scale fingerings;
- Search scales from fingerings;
- Search chords from scale;
- Search scales from chords.

What's New in Version 2.1

On the menu: Autoscroll, better PDF’s and some other treats.

New autoscroll feature for songs. Each one can have its own scrolling speed. You can specify a target duration or directly the speed, and some optional delays.

New PDF rendering engine. The layout is enhanced and now fully customizable. You can tweak almost everything, from the color of each element to the space between two lines of lyrics.

You can now batch assign line types in the song import module, which is also more robust.

Some enhancement for the Reverse Chord Search algorithm which now include usual omissions to give more musical results (this can be disabled in the settings).

Ukulele and banjo are displaying again standard fingerings in first positions. You don't have to manually switch of the "Root is bass" setting anymore.

Some minor bugs and display glitches were fixed too.

...and still a lot more to come!

As usual, if you spot a bug or have some suggestions, feel free to contact me.
If you like the app, leaving a review or sharing with your friends is the best you can do to support it!

Incredible Update

This is an amazing update to an already amazing app. I especially love the new songwriter feature, iPad compatibility, and iCloud sync!

This is the best reference app I have ever used for guitar and many other stringed instruments! It is packed with features and beautifully designed and executed. The way the app calculates chords and scales instead of storing an image for each one opens it up to so many possibilities, from quick chord analysis to reverse searches (inputting the notes you're playing to find out what chord it is). I just love this app!

Pretty good but has potential to be great.

Very good app but there are a couple things I wish it had. For writing songs I wish it had a tab style document. Also the reverse chord lookup does not work as well as I thought it would. Then lastly, I wish it had more descriptions on what makes a key of a song and what 5, 7, and 9 mean. This is not the greatest for beginners/mediocre players. Overall great app for reference and more advanced players.

The best just got better...

I was just thinking today I was wishing for auto scroll and I open the AppStore and here it is. Love this app.

Original review:
This app is incredible! I've finally found an app that lets me easily add chords to songs. This is gonna be a lifesaver.
And that's just one of the many things it does. If you play any fretted instrument, buy this app.
