Root Shuffling
The root jumps to a new pitch periodically during gameplay — the same noteset is reseated on a fresh root, building the ability to summon the noteset by its type from any root. This makes playing in any key trivial.
The major scale — the most familiar sound in Western music
Ionian is the major scale — the most familiar and foundational major major mode, and the most common scale in Western music. Bright, resolved, and stable: the default sound of nursery rhymes and most pop and rock. Its major pentatonic subset is the innate human melodic scale.

A scale is a set of notes used melodically, and a source of chords. The usual way to practice one is up and down — which teaches the fingering and not much else: the sequence is always the same, so the ears have nothing to decide.
NoSheet's way is non-linear: a short, randomized phrase from the scale sounds, and you play it back. Every phrase is new, so you keep hearing where each degree sits against the root — the 3rd bright, the 7th pulling home — and you learn to reach any note of the scale from any other, not only the next one up. In Root Shuffling the root jumps every so often and the same scale is reseated on it, which is what makes playing in any key trivial; in Range Shifting the root stays and the octave window walks across the instrument.
Start with the pentatonics — five notes, no semitones, the scale that sounds good almost anywhere — then add two notes for the major scale, and hear the minor as the same seven from another home.
On the mandolin: four courses in fifths, G D A E, the first twelve frets. The 6 exercises above are the loop with the scales decided — the panel still offers every setting, and a link carries yours.
