Rote memorization is not the way to learn all the notes on the guitar fretboard. This app will show you techniques and visualizations of patterns to make it easy to navigate the guitar in any key or mode, with a practice mode to reinforce what you learned. Also includes a chord mode to visualize the interval relationships on each string for a given root note. Fret distances are to scale with a configurable scale length and you can specify 6 or 7 strings.
