G Melodic Minor — Cavaquinho

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

Minor at the bottom, major at the top — the b3 keeps it minor while the natural 6 and 7 lift the upper half into a smooth climb home. Bittersweet rather than dark, with a polished, modern-jazz sheen.

Heard in: Jazz lines over minor and altered chords, film scoring, and classical melodies rising to the tonic — Bach, Mozart, and bebop alike.

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.
