Chordology - Chords and Scales, Beautifully Visualized

See music. Hear music. Understand music.

Chordology is the cleanest, most colorful way to explore chords and scales across all your favorite instruments. Whether you're a beginner learning your first shapes or a seasoned player digging into theory, Chordology turns abstract music concepts into something you can see, hear, and feel.

EVERY INSTRUMENT, ONE APP

Browse chords and scales for:
- Piano
- Guitar
- Bass Guitar
- Banjo
- Ukulele

BUILT FOR THE WAY YOU ACTUALLY PLAY

- Custom tunings (Chordology Pro): set up any tuning on your stringed instruments and see every shape update instantly.
- Capo support (Chordology Pro): dial in your capo position and view chords exactly as they'll sound.
- Multiple finger positions: for guitar, bass, ukulele, and banjo, swipe through every voicing up and down the neck to find the one that fits.
- Hear it instantly: tap play to hear any chord or scale rendered authentically on your chosen instrument.

GO DEEPER THAN SHAPES

Every chord comes with rich musical insight. Explore qualities like brightness, darkness, and consonance to understand not just how a chord is played, but why it sounds the way it does, and how to use it in your own music.

AN INTERFACE AS BEAUTIFUL AS IT IS USEFUL

Chordology's signature color system gives every note its own identity, so patterns leap off the fretboard and keyboard. The clean, bright design keeps the music front and center: no clutter, no noise, just clarity.

CHORDOLOGY PRO

Chordology is free: every instrument, every chord and scale, every voicing, and playback, at standard tuning. Chordology Pro is a one-time purchase - no subscription - that adds alternate tunings, a capo on any fret, and sharing.

Pick an instrument. Choose a chord or scale. Press play. Start exploring.

Download Chordology and see your music in a whole new light.

Thanks for using Chordology — I would love to hear what you think! 3.0.0 Jun 29 - Fixed issue with chord selection caused by iOS 14. 2.3.1 12/28/2020 Big update to how the chords handled. Currently, there are around 600,000 unique chords, each of which may have 20+ positions on each instrument.
This uses a huge amount of data, so i've had to re-think how they're generated and stored.
The method used for storing them has changed, which means faster loading times and far more chords (previously I had to leave out inverted chords as it increases the number of chords tenfold).

The lack of inversions meant that a lot of common Banjo and Ukulele tunings weren't possible!

- All possible inversions can now be selected for each chord (For example, a Cmaj chord with the G or an E as the lowest note).
- 4 String Tenor banjo added along with sounds. More banjo tunings to follow.
- Improved the quality of sound playback.
