About Guitar Machines!

Quinn Fetrow's Guitar Machines is a free tool to help teach you basic music theory concepts on guitar! I've got 4 guitar machines for you: 1. Note Machine - Teaches the notes on the fretboard one at a time, with options for randomization! 2. Scale Machine - Learn whatever scales you want in context of the CAGED system or use the "Custom Cage" setting to generate scales within a range on the fretboard. 3. Arpeggio Machine - Learn the arpeggios through the circle of fifths, or create your own arpeggio by selecting the notes of the chord. 4. Song Machine - Visualize the arpeggios of a song as it plays through its progression. I want you to learn how to play guitar!
