E Ionian — Charango
Here is E Ionian across the neck, home lit at every occurrence, ready to strum and hear.
E Ionian is 7 notes to the octave (modes family), drawn here across the Charango's GCEAE courses with every E marked, so home stays visible from anywhere in the pattern.
Bright, resolved, and stable. The foundation of Western tonal music and the most common mode in pop, classical, folk, and jazz.
Heard in: Pop, classical, country, folk, gospel — the default major tonality of Western music.
Five courses tuned GCEAE spread a scale wide for a strumming instrument: two courses share the same pitch class an octave apart, so a run can cross the twin E and land on the same note it just left. These maps mark every root so a line never loses home mid-course.
Practise it as a shape the whole hand crosses, not a ladder one finger climbs: pick four of its notes, rake them as a two-bar phrase against a slow pulse, then slide the same phrase to the next position. That is how this instrument actually uses a scale — raw material for a strummed line.
