Is this you?

01You know some theory and still cannot find what you need across the neck in real time.
02You want a more visual, intuitive approach to music theory and the execution of musical ideas on your instrument
03You want strong visual feedback/assistance on what you are actually playing, as you play it.
04You work with pitch sets and interval structures rather than conventional musical identifying terms.
05You want to learn an instrument faster, no matter the tuning or number of strings.
06You need a practice coach

What it is

Scale Demon is a music education app for guitarists and other musicians who want a more visual way to explore scales, chords, pitch sets, interval patterns and fretboard structure.

This application is designed around real-time musical input, practice feedback and deeper fretboard understanding — driven by any MIDI-generating instrumen. Feed the demon notes via a pitch-to-MIDI plug-in, a hardware guitar synth or a MIDI keyboard — even an EWI will work! Select a fretboard and keyboard visualizer -- whichever work for your way of learning.
