***** THE CHORD WHEEL; The Ultimate Tool for All Musicians *****

The Chord Wheel is a revolutionary device that puts the most essential and practical applications of chord theory into your hands.

This tool will help you:
UNDERSTAND CHORDS - Know the 'when, why and how' different chords work together.
IMPROVISE & SOLO - Talk about chops! Comprehend key structure like never before.
TRANSPOSE KEYS - Instantly transpose any progression to any key.
COMPOSE MUSIC - Watch your songwriting blossom! No music reading is necessary.

"I have given this information in lectures for years, but it's great to just tell people to go to your website and buy this thing. It's an amazing way to understand tonality and harmony."
- Bonnie Hayes, Songwriter “Have a Heart” and “Love Letter” from Bonnie Raitts’ multi-platinum, multi-Grammy ‘Nick of Time’

"This is the kind of device that players of any instrument can use to enhance their musical understanding. Chord and key relationships are inseparable, and learning these relationships is a must in becoming a successful musician."
- Alan Remington, Orange Coast College Music Dept.

The word of mouth from the first 100,000 customers as well as recommendations for countless teachers worldwide has made The Chord Wheel the most successful device of its kind. Countless testimonials from users (see Amazon.com for numerous examples) assure you that this will help you in your quest to become a better musician. This product is intended for beginners and intermediate students; if you can rattle off the chords of a ii-V7-I progression in the Key of Bb and know whether a C7 sound good in this key without thinking about it, you may not need it. For the rest of us, here is the answer.

Though it's still primarily intended for musicians, the iPhone App version allows users to depress the wheel's cells and hear the chords played back in the instrument and chord voicing selected in the 'Settings' page. The result is an entertaining song composer that allows you to play chord progressions without any musical knowledge whatsoever. For musicians, it allows your ears to hear the relationships between chords and key.

Nice but a few bum guitar chords

The wheel is a helpful layout for writing simple major/minor progressions. Piano sounds are bold and in tune, and sustain for two good legato whole notes while you consider the next chord. However, some of the guitar chords are well out of tune, and one or two of the diminished 7ths are downright wrong on guitar. But the majority are OK. I stick with the piano.

This would be excellent tool if there was a simple way to toggle any chord to and from its 7th, 6th, sus4, or 2nd/9th — or maybe add the note on the keyboard (which in inactive and purely decorative). But overall the wheel is a nice idea for establishing harmonic context.

Please Enable Rotate to Portrait Mode

I bought the book and will find the app useful as well. I’m happy that the issue with the sound has been fixed but would like to be able to use the app in portrait mode. Landscape feels clunky and using the app in portrait wouldn’t mean the wheel is obstructed in any way. It’s just a circle. But the device you’re using would be more comfortable in hand.

Great app

I'm so excited to see this app! For years I thought it should be easy to make an intuitive chord wheel app but couldn't find one that was easy to use and display all of the info I was looking for. The only thing it's missing is the note numbers in the scale. A lot of chord wheels online show a small Roman numeral to represent the chord number under the letter. That addition would make this a 5 star app.

Go through the tutorial. You can zoom into the key signature
