Capo helps you learn to play the songs in your music collection by ear. Its sophisticated, easy-to-use features will have you learning to play more songs in less time.

• GET THE CHORDS: Capo analyzes the songs you load by "listening" to them, and then displays all the chords it hears. In addition to naming the chords, Capo can show diagrams for guitar, ukulele, banjo, mandolin and 4-6 string bass players. When Capo misses a chord, or gets it wrong, you can correct the detected chords easily, and your changes get saved with the song. You can specify alternate chord voicings, and for all you lefties out there: we've got you covered with our left-handed display mode. Rock on, southpaws!

• CHANGE THE SPEED: Slow down (or speed up) your music without changing its pitch, so you can practice with the recording at a comfortable pace. Its high-quality time stretching engine ensures that your music sounds great at any speed. Export your speed-adjusted songs for use in other applications or devices.

• CHANGE THE KEY: Quickly transpose your music to a different key so you can play or sing along with it comfortably. The chords and chord diagrams update immediately to reflect the new key as you drag the pitch slider.

• LOOP PLAYBACK: Loop sections of a song for practice or sharing by creating regions. Simply drag on the waveform to create looping regions that snap to the beat and loop in time with the original recordings. Name the looping regions or colour code them to stay organized. Or export your regions for use in other applications.

• EXTRACT OR ELIMINATE INSTRUMENTS & VOCALS: With Capo's cutting-edge isolation effect, you can more easily hear the parts of a song you are trying to learn by simply adjusting a few sliders. Extract the sound of a single instrument/vocal to hear it more clearly, or eliminate it to create a custom backing track.

• GENERATE TABLATURE: Record the notes you hear in a song — simply by using your mouse and clicking the notes you see on the spectrogram. No longer do you have to keep a notepad at hand to transcribe solos, because your transcriptions are saved for when you return to learning, or playing a song.

• ADD A 'VIRTUAL CAPO' / CHOOSE ALTERNATE TUNINGS: Quickly audition a song's chords using different frets and alternate tunings so you can find out where it’s most comfortable to play, or to better match your instrument. When setting a fret to place a "virtual capo", Capo automatically adjusts its chord diagrams so they are displayed in relation to the capo.

• METRONOME AND COUNT-IN: Rehearse like a pro and improve your timing by playing along with a song-synchronized click track. Use the count-in feature to give yourself a bar or two to take a deep breath before rocking out with your favorite songs.

• SAVE CHANGES & COLLABORATE: All your work while learning a song (e.g. editing chords, creating loops) gets saved in a 'Project' while you work. When you open that song again, you’re ready to pick up where you left off. You can also share your projects and collaborate with students, friends or bandmates using email, AirDrop, Messages, or simply by copying the project to another Mac.

• SHARE PROJECTS BETWEEN DEVICES: Easily share your work between your Mac and your iPhone/ iPad, when you also have Capo touch (purchased separately from the iTunes App Store.) Using iCloud, changes you make to your songs are kept up-to-date on all your devices so you can be ready to continue where you left off whether you made the changes at home on your computer, or while traveling on the road.

• LOAD MUSIC FILES: Capo can open, play and analyze the songs you purchased from the iTunes Store as well as MP3, M4A, AIFF, and WAV audio files.

Note: As with all apps, Capo cannot play music that is protected using Digital Rights Management (DRM) technology. This includes streaming content from Apple Music and other services.

What's New

Version 3.5.7

We spent a lot of time reworking the music processing pipeline that powers Capo’s chord, beat, and key detection. This work should improve the overall accuracy of Capo’s results, and it paves the way for some features that we plan to add in the coming months.

Bug Fixes:

• The playhead should no longer stick to the right-hand side of the window when playing loops
• When loading a project, the saved time signature is now shown correctly
• When creating regions, dragging outside the view's bounds will now scroll as it does when resizing them
• The 'Detect All Chords' feature now indicates that it is running in the status area

We love hearing from our customers, so please leave a review on the App Store to share your positive experiences with others, or send us a support email if you have any questions for us. We're listening, and appreciate all your bug reports and feedback!

Useful. Not perfect, but improving.


The developer keeps improving this app, and I have found it quite useful. If you’re an aspiring musician, it’s worth the very reasonable price for the parts that work well. It cannot always deliver on getting chords right, particularly on more complex songs (although I have not tested this on the most recent version yet). The best thing about Capo is the ability to slow down the tempo while keeping it in the same key, or pitching the song up or down while keeping the same tempo. You can also mute out certain ranges of sound so that you can play along without doubling the part. It does these things very well.

Developer Response

Thank you so much for this insightful review of Capo. You're right — Capo doesn't always get the chords correct. Obviously, our goal is to get as many chords correct as possible. But for the ones it doesn’t, we have made it simple for users to correct the missed detections. All the changes you make to a song’s chords are stored in the Project as you go, so your modifications will remain intact the next time you return to work on a song. We have a blog post written by the developer of the app that talks about Capo's chord intelligence in greater detail if you're interested. You can find it here — —
Thanks again...

Absolutely amazing!


I had been using Riffstation which is OK. Then I tried Capo! What a major difference. Being able to change pitch along with speed is great, but the best feature is how easily you can isolate an instrument or voice. The chord identification feature is accurate! I trully recommend this app! Version 3.5.4 is awesome! Thanks!

Feature Request


Can you please add the abilty to make custom sized marker regions that don’t snap to the grid/beat, just like you recently did for the iOS app? Thanks!

Developer Response

You can do this in Capo! Regions created in Capo will automatically snap to the beat. However if you wish to disable snapping to the beat grid, hold the shift key while dragging the Region with your mouse.
