Chord! is a chord and scale reference that works with any fretted instrument like guitar, basses, ukulele, banjos,… It computes and analyses all the possible fingerings for chords, scales, and arpeggios.

With Chord!, you can also 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). You can also link audio tracks from your music library and play them at the same time while adjusting their pitch and/or speed.

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 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 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. Chord arpeggios are also supported, as well as drop voicings (drop 2, drop3, etc.).

The app also ships with the biggest list of named scales (and you can create your own 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) and compute their fingerings. 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 that ship with the app, or you can add your 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 finger 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 a 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 with 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 supports 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.

Fantastic tool.

I am not a stringed instrument player, they have confounded me for decades (honestly it's a cognitive disconnect). But with this tool I finally feel in command. I tell it what I want to play and how I want to play it and it shows me how to accomplish that goal. I tell it that I want to see what that song would look like on a completely different instrument or tuning and it shows me... Fantastic. The app itself is deep and complex and could benefit from some simplification in the UI. If I had not been someone who has been using computers for music since the 80s I might have been a bit more lost. As it turned out, I still found it challenging. The developer needs better documentation and a good set of how to movies right away. To avoid people getting frustrated. I did have a problem with the app not showing me common fingerings of basic mandolin and ukulele chords but I emailed the developer and got a response that was honest and clear the same day. I am confident he is actively working on this project and dedicated to making it better. Good thing too, because it is great. If this had been available 30 years ago I would be calling myself a string player today.

Thanks so much for the Apple silicon version! I don’t have a M1 Mac yet, but I will soon and it’s great to know I will be able to use this there as well.

My most used music app!

I have bought well over 30 musician apps to help me become a better musician but this one is my most used app. I use it every day!! Sure it has chord look ups and cool features, but my biggest use case is to use it for live setlists. If you are playing live at a gig, it’s helpful to have your list of songs with their chords and lyrics. This app makes that so easy to do! Just import a regular chord text file and it recognizes which parts are chords and which parts are lyrics. You can then group and reorder all your songs into set lists. What is really cool over other set list apps is the fact that you can customize a chord to the specific one you play and with an easy replace function it allows you to apply your special chord to the entire song!
It even has an auto scroll function plus a way to associate the song with an Audio track so you can play along with your own backing track.

This app is so powerful, the only downside I see is that it has a steep learning curve and I which there were better tutorials to help people learn what took me a little while to pick up!

This app is the best for so many reasons

The first thing that turned me onto this app is when I saw a Sweetwater music demonstration and I saw that you could do a reverse chord & scale search. That is invaluable for those of us who don’t have perfect knowledge of theory or have every chord and scale memorized. It is so immensely helpful when I write a riff (sometimes it’s some crazy jagged odd notes I add in for a color) and I can enter the notes into this app and have it not only tell me what scale it is but also easily see all the other notes connected across the neck. That’s not even really scratching the surface here though. You can also add extra strings to your virtual guitar so regardless of what tuning or how many strings you have (Bass/ or Guitar)it will accommodate you. You can view the notes across the piano or a guitar neck as well. I’m sure other reviewer‘s have more in depth reviews, but those are the things that were the dealbreaker for me and I wouldn’t wanna have to be without this application. Thank you to the developer😉🤜🏻🤛🏻
