Capo
Learn more songs in less time
Only for Mac
Free · In-App Purchases
Learn your favorite songs without tabs or sheet music.
Whether you play for the world or yourself, all musicians need a good ear for harmony, melody, and rhythm. Using the songs in your music collection, Capo guesses the beats, chords, and key of songs to help you break them down to their individual parts. Capo’s unique technology helps you to learn your favorites quickly as you improve your ear along the way.
Capo is simple and yet so, so good, even the professionals use it:
“Capo is AMAZING!!! Very clutch. Especially when parts are kinda tough in the mix that I can’t make out easily. With other apps you lose quality, this still sounds correct.”
- Omar Edwards: Keyboardist/Music Director for Jay-Z, Rihanna, Kanye West, Eminem, and more
“When I sat down and started using Capo for the first time, I was amazed at how big a punch this little app packs! It's intuitive, convenient, and high-quality.”
- Rebecca Lovell: Lead Vocals, Electric Guitar, Acoustic Guitar, Mandolin, Piano for Larkin Poe

*** HEAR THE SONG ***
Slow down playback, scrub to hear specific notes, and easily create regions that loop as you learn to play the tricky parts. Use Capo’s tools to isolate specific instruments and even vocals to learn any part of a song. With a couple simple switches, you can focus on the piano or eliminate everything to practice the guitar solo and make transcription easier.
*** BREAK IT DOWN ***
Capo automatically detects chords, beats, and the key of songs to get you started. Change, add, or remove the detected chords easily with a few taps as you identify alternate chords and voicings. Use Capo's structure song view to edit Capo's beat grid for songs with changing, or uncommon time signatures.

more Great update. Forget my last comment if ever you read it, I just hadn’t expored all the new features. ThxP.S. My computer is set in french language and the word « Key » in your app is translated to « touche » which means like « computer key », not the actual key of a song. The right word would be « clé ».

App claimed an extremely short trial period to use on a trial basis, however, even worse, within the first 90 seconds of use the app reported that sound quality would diminish and it did. White noise overlapped the music to the point that it was a complete waste of time to use, let alone explore. Not only is the app too expensive for what it is in the first place, the developers are deceptive in their marketing approach.
Developer Response Capo's latest 4.0 update has removed the playback timer and sound degradation, and considerably improved its free feature set offering. Please give it a try and let us know how it goes!

I wanted an application that was more versatile than Apple’s Music. With Capo I can change tempo, see chords, use a metronome. Very helpful for audio and ear training, especially when there is no sheet music.

This maintenance update addresses bugs that were reported by our users over the holidays. Happy New Year, everyone!
# Bug Fixes
- After dragging to adjust the size of a region, Capo once again ensures that the region remains selected. This regression was introduced in the 4.6.1 update, and we regret the error.
- When executing the `resizeRegion()` command from a keyboard or MIDI binding, Capo no longer interrupts the in-progress playback by seeking to the start or end of the region. However, this seek still happens while playback is stopped, so that the new boundary location is reflected in the position display.
4.6.2 Jan 8
This maintenance update addresses some minor issues reported by our users. Thanks everyone for providing your feedback!
# Bug Fixes
- The mixer popover now appears correctly after pressing the toolbar button.
- When using the previous/next buttons in the Marker, Region, and Chords toolbar items, Capo will now move to the beginning/end of the song after the last item is selected. This matches the behavior of the buttons in the Control Strip on iOS.
- Capo now has improved selection management, where you can no longer have a Region, Marker, and Chord selected at the same time. This problematic state was characterized by three trash cans appearing at once in the toolbar, which is no longer possible.
4.6.1 2025-12-15
Capo is now ready for macOS Tahoe, sporting an all-new control layout that feels right at home on your Mac.
# New Features
## Goodbye, Control Strip. Hello, Toolbar!
- We moved all of Capo's controls from the Control Strip to a standard toolbar that looks and feels very familiar on the Mac.
- If you right-click on the toolbar, you can now customize the layout to rearrange controls however you want.
- Each song view has its own toolbar layout, so you can tailor your selections to fit how you work with Capo.
## Capo has an all-new icon!
- We were ahead of the curve in 2020 with our glassy icon design, but we tweaked it for macOS Tahoe---it appears more vibrant, and works great with the dark, clear, and tinted icon styles.
# Enhancements
- Under the hood, we cleaned up and modernized our code to work best with the latest OS releases.
- We also improved the scrolling and layout performance, so Capo should feel as glassy and smooth as the new look of macOS!
- If you set a custom colour theme in your System Appearance Settings, Capo now reflects that colour in more places in the UI.
- Improved scroll behavior at the song boundaries - Capo now consistently bounces the whole content area of the Practice and Tabbing song views together as a single unit.
# Bug Fixes
- Capo no longer gets stuck in certain scenarios when you trigger a selectPrevious(.region) command from a MIDI or keyboard binding.
- When Capo is scrolled to the end of the song, playback now runs more smoothly, without the major CPU usage spike that may have impacted audio quality on some machines.
4.6 2025-10-10
This update contains bug fixes and improvements based on user feedback and crash submissions.
# Bug Fixes
- Guitar chords for 7(#9) now correctly include the "Hendrix style" shape (e.g., E7(#9) should have x7678x in the list)
- In the Practice and Tabbing song views, you should no longer see chords, regions, or time labels disappearing at random
- The chord settings now appears with the correct popover animation in the Chords song view

# Bug Fixes
* Capo should no longer crash on launch for long-time users with legacy keyboard command definitions in their preferences.
* When Capo encounters unexpectedly formatted receipt data from the App Store, either at launch time or soon after a purchase is completed, it should no longer crash.
4.4.1 2025-05-09
# New Features
**Remote Control:** On macOS 14 and later, Capo now offers expanded integration with MIDI foot pedals, control surfaces, and keyboard controllers. You can now use continuous controls like knobs, sliders, and expression pedals to change playback speed or adjust Capo's built-in mixer in real time. Additionally, we've enhanced keyboard shortcut customization to distinguish between keyDown and keyUp events, allowing for more sophisticated control configurations. Consult the new chapter in the User Guide for more information about this exciting new feature.
While you try the Remote Control features for as long as you wish, a subscription or previous purchase is required to save all your command bindings. So we hope you’ll try it out, fall in love, and subscribe today!
# Enhancements
- In the Structure Song View, you can now right-click on bars to create new sections.
- The Structure Song View now opens without an initial delay, and has been optimized to run quicker and use less energy.
- When subscribing, Capo now shows an improved “sales pitch” screen that provides much more information than before.
- In response to several user requests, Capo now offers a monthly Pro subscription tier.

This update contains bug fixes and improvements based on user feedback and crash submissions.
# Maintenance
* Capo is now built against Apple's latest SDKs while still maintaining its compatibility window back to macOS 10.13. This was a delicate, and extremely difficult set of changes that slowed progress to a halt for far too long.
# Bug Fixes
* Capo no longer crashes while zooming out on the timeline in certain circumstances.
* When using the keyboard to navigate chords in the PRACTICE song view, Capo no longer gets stuck on the first and last chords.

* Corrected some back-end errors that could lead to audio glitches in very rare circumstances while the system is under heavy load.
# Maintenance
* Updated Capo's code base for the latest Xcode toolchain, which required us to bump the minimum supported version of macOS to 10.13. This was a larger job than it should have been, but at least it's finally done now!

# Bug Fixes
* Capo no longer allows you to make invalid adjustments to the song's key using keyboard shortcuts.
* We resolved a handful of reported crashes that were triggered by incorrect logic that led to excessive layout in the PRACTICE song view.

4.3.1 2022-03-24
# New Features
## Larger Chord Sizes
You can now choose to display chords with a larger size, making them easier to read in the PRACTICE, TABBING, and CHORDS song views.
## Improved In-App Release Notes
Thanks to automatic updates, it's easy to miss out on the details of our ongoing work on Capo between larger releases. To keep you in the loop, we now ship Capo with a more comprehensive set of change history that goes all the way back to the 4.0 release that shipped in late 2019.
In future updates to Capo, you'll be prompted to view these release notes at your convenience, and you can revisit them at any time by selecting Help > What's New from the main menu.
# Enhancements
* When using pinch zoom on a trackpad while the cursor is over the waveform area, the zoom gesture is no longer interrupted, and the display refresh rate has improved somewhat.
* Chord boxes for 4- and 5-stringed instruments are now rendered slightly more narrow than the standard 6-string diagrams, which looks a little closer to what folks might expect
* Added support for a few chords that have been requested in support: 6add9 (aka 6/9), 7sus2, maj7sus2, 7sus4, and maj7sus4. (Note: You have to specify "6add9" in your chord searches, because "6/9" throws off our support for recognizing inversions. We plan to address this issue soon!)
# Bug Fixes
* When zooming in or out with keyboard shortcuts, Capo no longer loses your position when the playhead is close to the end of the song (#1807)
* Capo no longer shows truncated bar numbers in the PRACTICE song view on macOS 10.12
* You can no longer edit a project's filename from the window titlebar before saving it for the first time, causing Capo to crash (#1839, #1823)
* When switching your instrument to something other than a guitar in standard tuning, Capo now correctly remembers this selection for new projects (#1803)

4.2.1 2021-08-26

ENHANCEMENTS

4.0.1 2020-12-11
4th Generation Chord Detection (macOS 10.14+ Only)
Capo's newest chord detection engine is faster, more accurate, and identifies a wider range of chords—including inversions! If you'd like to read more about the development of this new technology, visit our blog at supermegaultragroovy.com.
You can re-detect and replace all the chords in your existing Projects by choosing Notes > Detect All Chords from the main menu.
Structure Song View (Subscription Only)
You can now see and mark up your songs at a high level—bar by bar—to define the sections of the song. Mark the Verse, Chorus, A Section, B Section, or use whatever names you choose! You can also apply colors to the sections to help you identify similar ones.
Many users will be excited to learn that this all-new song view _also_ allows you to edit Capo's beat grid that's used to power Capo's snapping and metronome features. By clicking along with the beat to mark the start of each bar, you can replace Capo's detected beats with your own. You can also change the number of beats in specific bars when you're working with songs that have mixed time signatures, and make fine adjustments to improve precision.
Chords Song View (Subscription Only)
An all-new, vertically-scrolling look at the chords in your song displays more chords on screen at the same time. It also uses the sections you define in the Structure song view to group the chords according to the section they belong in.
This is a massive improvement for chord-oriented musicians that are looking to analyze a song's overall harmony, or those that want a better view of what's coming ahead.
Trial Mode (Paid, Non-Subscribers)
If you are a paid user that has not yet subscribed to Capo Pro, you can try the new, subscription-only features as many times as you'd like, for as long as you'd like! Just select one of the song views that are marked TRIAL, and Capo will let you play with the feature with only one catch—your edits to the project will no longer be saved.
Don't see anything worth paying for? No problem! Close the project, and you'll be back to using Capo as usual. We will keep trying to earn your subscription in future releases, and hope you enjoy the massive improvements to the chord detection engine!
Improved Free Edition
The free version of Capo no longer has a playback timer! You now have full access to Capo's full feature set, but Capo will not save any of your edits to Projects without an active subscription.
This change results in a more useful product for a wider audience. Teachers, be sure to tell all your students!
ENHANCEMENTS
* We modified the Simple Piano chord display to make it easier to distinguish the bass note from the others.
BUG FIXES
* Capo no longer crashes in the chord chooser when searching for chord inversions
* We addressed a handful of crashes that were submitted by users since the last release. Please keep sending us your bug reports!
