Performing other people’s music is one of life’s joys whether you’re doing it to learn how to play an instrument, or singing I Will
Survive in a karaoke bar. Working out what other people are actually playing isn’t always simple, unless you have Capo.
Capo analyzes your chosen music to work out how to play it and presents the appropriate chord diagrams, and it gets the right chords most of the time. When it gets the odd one wrong, you can correct it and store that correction alongside the other chord information.
There are limits to what Capo can handle. MP3s and other major audio file formats are fine but streaming isn’t, not least because recording them is copyright infringement.
Capo worked flawlessly not just with clear acoustic music but with filthy electronic rock and layered prog, even your own creations. And once you’ve identified the chords you can mess around with them. You can loop sections, and speed up or slow down the music to make it easier to play along, and change the pitch if you wish.
Although Capo is mainly about learning guitar chords, it isn’t exclusively so. The pitch changing means you can work in the right keys for other instruments. You can even extract instrument solos or isolate vocals, or mute the solo or vocal. You can also extract audio and export it as MIDI for use in GarageBand or other audio software.
There are two downsides. First, the price: fifty bucks feels like a lot. Second, previous versions have been known to crash. The latest version is stable but it’s wise to try the trial version before you commit your cash.
the bottom line. A useful app, even if it lacks streaming support.
Capo’s ability is almost uncanny, detecting the key and individual chords.
