D Ionian on Vihuela

D Ionian runs 7 notes to the octave. Below it is mapped onto this instrument's A–D–G–B–E fretboard with every D marked, because what a player needs mid-number is not the pattern but where the root is when the harmony moves under it.

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.

The armonía is not a soloing section, so a scale here is diagnostic rather than melodic: it is how a player finds which tones a grip is actually putting in the air on a neck whose octaves do not run in order.

Take it slowly against the playback until the geometry stops being geometry, then put it under a number in D and let the written line pick its own notes out of it.
