Some people learn better by example. Instead of trying to learn from a "guitar for beginners" book, the Riffstation app, website, and desktop app—now owned by Fender guitars—will teach you the chords to your favorite songs in real time. It syncs up with videos on YouTube, and depending on how clear the guitar tracks are in the recording, allows you to play along with them. Within the app, you can adjust the tempo of songs, add a metronome, and switch between learning the songs on guitar, ukulele, piano, or mandolin. If you feel like you've learned the song, but it isn't in the right key for you, you change the key of the song with a virtual capo.
