From guitar chord finders to interactive chord namers and transposers (key changers), the web is full of freely available software that can help you learn more chords and better understand your chord playing.
Here's my run down of the best guitar chord software I've discovered on the WWW (all free!). Thanks to all the talented programmers/creators who offer these great tools to the guitar learning community...
Guitar Chord Finders
Chord finders show you how to play a chosen chord in several positions on the neck. Simply select your chord type, along with a root note, and watch it appear as a shape on the fretboard.
Oolimo Chord Finder - Basic Chord Finding
One of the newer chord finders and by far the slickest and easiest to use for basic chord finding. Simply select your root and chord type from the blocks below the fretboard and use the "prev" and "next" buttons above to cycle through several chord shapes/positions. You can also choose whether to use note or interval labels on the chord.
A nice additional feature is the "arpeggio" button, which shows you how these chord shapes form part of an arpeggio pattern right across the neck.
Fachords Ultimate Chords Dictionary - Detailed Chord Finding
The only chord chart with finger positions, note names and intervals on the same diagram. A wealth of voicings and positions for every chord imaginable, colour coded intervals/notes, a useful chord structure diagram and neck-wide roadmap for your chosen chord (great for learning arpeggios).
This tool is for those who want a deeper understanding of the chords they're playing.
JGuitar Chord Search - Map Out Your Progressions
JGuitar's Chord Search function allows you to simply type in the chord sequence you want, separated by commas, and it will display them all on the same page in a traditional chord chart style.
Very useful if you want multiple chords of your choosing displayed together in a chart.
Guitar Chord Namers
Chord namers, sometimes called "reverse chord finders", tell you the name of the chord you enter on to the virtual fretboard. This is useful when you want to transcribe your chords using symbols (e.g. Cmaj, Cm9, C7sus4) rather than charts. It's highly recommended that you spend a little time learning how to write chords in symbol form.
Oolimo Chord Analyzer
Another mention for Oolimo as the most accurate and intuitive chord namer on the web today. Click your chord shape on to the fretboard string by string and, not only does it tell you the name of the chord, but also offers several inversion names for that fingering and standard notation.
Click "up" or "down" to transpose the chord to different roots and use the "notes / intervals" button to select your fingering labels.
Chord Ear Training
Knowing how to play chords is one thing, but can you identify chords as they're played? This is a powerful ear skill that, if given enough practice, will allow you to transcribe entire songs by ear. Here's the perfect tool for the job...
Fachords Chord Recognition Game
A one-of-its-kind tool that plays different chord types and challenges you to select the correct chord type from two or more options.
Starting with major and minor chords, and moving to more complex chords such as major 7th, diminished and minor major 7th, you'll be surprised at how quickly you can train your ears to identify chords.
For a more comprehensive course on all aspects of ear training, I highly recommend Musical U.
Have the chords to a song but want to change the key? No problem...
Either type or paste in the chords to your song and use the up and down arrows to change the key. The tool will automatically change each chord you've entered to fit that new key. You can then print the revised song sheet if you wish.
Not only that, but it displays chord diagrams for the new key so you won't be second guessing where to put your fingers. Hover over the chord symbols to see the individual chord diagrams. Simple, but very effective.
Multi-Purpose Chord Tool
Finally, the granddaddy of them all...
All Guitar Chords
Brings together every chord tool you could want into one menu. Including innovations such as "chords to scale", "scales to chord" and an interactive circle of fifths, this site has always had a prominant place in my bookmarks bar.
While not quite as "slick" as some of the other tools featured on this page, it does offer the widest range of tools in one convenient place.
Please support the creators of these sites in any way you can and I hope you have as much fun using them as I do.
If you know of any other chord software/tools that deserve mention, please let us know using the comments function below. Cheers!
