Description
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!
