Everything You Need to Master Songs by Ear
Chords for Your Instrument
See chords the way you need them. Capo displays chord names, piano diagrams, or fingering charts for guitar, ukulele, banjo, mandolin, and 4-6 string bass. Switch between displays instantly—whether you're a keyboard player, a guitarist, or just want simple chord names to follow along. Lefties can even flip to left-handed diagrams.
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.
Pick Up Where You Left Off
Capo's Projects remember everything—your chord edits, loop regions, playhead position, even your speed and pitch adjustments. Come back days later and you're instantly ready to continue learning, not scrambling to recreate your setup.
Why Musicians Love Capo
Such a valuable tool!!
★★★★★
I grew up dropping the needle over and over to learn guitar parts and solos. It was painstaking and difficult but that was the way we did it. Today, Capo makes the process of learning parts seamless and so easy — input the source material, take control of tempo, key, etc and set up regions for looping, all of which takes seconds to do. Amazing. Also a great tool for developing original music.

Wonderful helpful app
★★★★★
When I'm trying to learn something by ear I need to slow down the music while keeping audio quality … capo is great. YouTube has limited ability in this and the audio quality degrades. Also Capo transposes, and offers chords. I can't count on the chords 100% but they get me on the right track… my ear is my weakest link and it keeps improving. Capo helps tremendously.

“Whether I go to learn a song myself or teach someone how to play a song, I bring it up in Capo.”
Read about Capo's use in Education ›Capo’s a lifesaver, it truly is! I always carry my iPad, and now I can use Capo there and on my computer. I love the initial auto chord detection and the Add Chord button to catch every detail of the performance.
Capo fits perfectly when there’s a lot of music to chart and not a lot of time. You always try to write a chart in order to memorize the song form. If you can throw it into Capo, it gives you that basic chart form right away.
The chord detection in Capo touch is great, where I need it the most—on the fly in a rehearsal studio. Useful, easy to understand, and packed with features, Capo is the secret weapon for figuring out how a song is played.
I love Capo! What a useful piece of software! I find myself constantly referring to it for so many things, from transcribing my favorite solos to learning new arrangements. Didn’t think I was missing it until I started using it.
