SUS4 Scale Lab
Every mode and scale, visualised on your instrument.
SUS4 Scale Lab shows every scale and mode visualised on your instrument. Pick a root note and a scale type, and the app shows you where the notes fall (on a fretboard, keyboard, or other supported layouts) across iPhone, iPad and Mac.
The library covers the full range: major and minor, the seven diatonic modes, melodic and harmonic minor and their modes, pentatonics, blues scales, whole tone, diminished, and more. Each scale is shown in the context of the instrument you are working with, not as an abstract set of intervals.
Scale Lab is useful whether you are learning a new scale, checking which notes belong to a mode, or working out where you can take a melody. It removes the lookup step from practice and composition so you can stay in the music.
