D Aeolian — Cavaquinho

D Aeolian is 7 notes to the octave (modes family), drawn here across the Cavaquinho's DGBD strings with every D marked, so home stays visible from anywhere in the pattern.

The standard natural minor scale — melancholic, introspective, and deeply emotive. The most common minor sound in Western music.

Heard in: Pop, rock, classical, metal — the default minor sound of Western music.

Four strings tuned DGBD put a scale somewhere honest and a little cramped: two or three notes to a string, no spare string to hide on, and every open pair climbing rather than doubling back. These maps mark every root so the top voice never loses home mid-run.

Practise it as a fill, not a ladder: pick four of its notes, drop them into the rests of a batida cell, then slide the same four to the next position. That is how this instrument actually uses a scale — a top voice riding above the chop, not a run played alone.
