See music the way you need

With Capo you can learn songs in an intuitive and flexible way. The automatic chord detection appears when you load a song from iTunes, and updates instantly if you change key, place a virtual capo on your instrument, or switch tunings. But there’s more to what you can now see in the music you’re learning! Capo makes it easy to learn the details of a music performance using the visual representation of frequencies in an audio file called a “Spectrogram”. Swipe across notes to instantly generate guitar tablature and also see every performance nuance - the note bends, slurs, and vibrato - to reinforce what you are hearing.

Slow Your Music

Capo can slow down your favorite music without affecting its pitch, so you can practice along with solos at a comfortable pace. Capo employs a mastering-quality time stretching engine so your music sounds great at any speed.

Automatic Chord Detection

Capo saves you time by automatically detecting chords when you open a song. Quick edits to the chords can be made with a few clicks, or by entering simple strings such as ‘bmaj7’ or ‘f#maj9’.

Easy Transposing

Capo lets you instantly change the key of your songs using an easy pitch slider. By simply holding the shift key, you can also adjust the pitch of a song finely to correct a recording that’s out of tune.

Chord Boxes

Tab it Out!

Looping Regions
