Riffstation is a desktop application for Mac and Windows computers. Load any MP3 and Riffstation will automatically detect the chords and sync the chord diagrams with the music. You can also slow down the audio, change the pitch, isolate or mute guitar parts, loop specific sections and even sync a metronome!
The app scans songs and show you the chords used throughout, complete with finger placement guides. You can even specify capo placement, or switch between open and power chords. It’s not perfect, but it’s a great way to start learning any song on your guitar.
And there’s a lot more to unpack here. You can break down songs into smaller chunks, called riffs, and play them in slow motion loops, giving you time to figure out exactly how to play them. You can even isolate the rhythm from the lead guitar, allowing you to only hear one or the other.
