SuperMegaUltraGroovy Capo Pro 4

Learn songs from recordings without tabs or sheet music.

Music players are built for listening. Capo is built for learning by ear. Slow down without losing quality, loop sections perfectly, restart from any note, detect chords instantly—everything you need to master songs is right there. Stop fighting your player. Start learning faster.

See Chords Detected in Seconds

Load any song and Capo identifies the chord progression throughout the entire track. Get accurate results in seconds instead of hours of trial-and-error. The detection gives you a head start while you develop your ear—you'll naturally recognize patterns as you play along.

Hear It, Draw It, Confirm It

Carefully scrub through audio to hear individual notes clearly. Draw what you hear onto the spectrogram, and Capo plays it back so you can compare your interpretation with the recording. See bends, slides, and vibrato that help you capture the real technique—and as you draw, tablature is generated automatically below.

Refine Every Detail

Capo's chord detection is accurate, but not perfect. Sometimes it's overly specific, sometimes not specific enough. Simplify a complex extension, add nuance that was missed, or choose a voicing that better fits your playing. Every chord is editable—the automatic detection saves you hours, then you fine-tune exactly what you need.

Everything You Need to Master Songs by Ear

HEAR NOTES MORE CLEARLY: Adjust playback from 25% to 150% speed without changing pitch, and freeze audio to isolate individual notes. When fast solos and complex passages fly by too quickly, slow them down to hear every detail at your own pace.

PLAY IN ANY KEY: Transpose any song to a comfortable key and all chord diagrams update automatically. Match your vocal range, avoid awkward fingerings, or accommodate other instruments—without having to figure out the new chords yourself.

LOOP IN TIME: Capo's beat detection automatically finds bars and beats, so you can create looping regions that snap perfectly to the measure. Practice challenging passages endlessly with beat-perfect loops—build muscle memory without awkward cuts or timing issues disrupting your flow.

PRACTICE WITHOUT INTERRUPTION: Control playback, looping, and speed without touching your mouse or trackpad. Map MIDI pedals or keyboard shortcuts to keep your hands on your instrument while you practice—no more breaking your flow to reach for controls.

WORK NOTE-BY-NOTE: The transcription playhead stays exactly where you place it, letting you focus on one phrase at a time without fiddling with controls. Hit play, listen, stop—it always starts from the same spot. No hunting for your place, no losing your flow. Since you can only hold a few notes in working memory at once, this approach helps you master complex passages methodically instead of getting overwhelmed.

FOUR VIEWS, FOUR WAYS TO LEARN: Capo adapts to how you work. The Chords view displays your song as a chart—perfect for playing along. Switch to Tabbing for the spectrogram when you need to transcribe solos note-by-note. Use Structure view to see and navigate song sections at a glance. Or stay in Practice view for streamlined playback control. Each view gives you exactly what you need for that moment, nothing more.

All Musicians Welcome

Don't play guitar? Doesn't matter! We have users who play all kinds of instruments—piano, banjo, drums, ocarina, fiddle, and more. And their skill ranges from beginner all the way up to Grammy-winning artists. If you want to learn from recordings, then Capo is the tool you need.

Why Musicians Love Capo

Great for Practicing! - It's great for slowing down songs without losing much fidelity and learning the song by ear. I've been using it to take out hard riffs by ear with odd time signatures. Capo is definitely my go to. I love the loop feature and being able to zoom in on the wav file to get a precise loop going.

Excellent Resource - I use this app for learning songs daily. Very user friendly. I'm especially impressed when on the rare occasion there is a problem, the developer responds to my email with updates and fixes.

Just what I needed - Capo has helped me so much. I've used it for learning guitar parts, practicing singing, and so many other things. It's a mainstay in my musical toolbox—thank you!

Made With Love for the Mac

We've been building and shipping software exclusively for macOS since 2004, and won two Apple Design Awards along the way for our platform expertise. Capo was crafted with care to ensure you always have a great experience on the Mac: it has a native look & feel, and runs great on all supported Apple hardware. We were there on day one with support for Apple Silicon, Liquid Glass, and you can be sure that we'll be ready for whatever upgrades you have planned for the future.
