F Melodic Minor on Guitarrón

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

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.

The bass takes almost no melodic line, and that is precisely why these matter: the notes between one root and the next come out of a scale, and an approach that lands wrong is the loudest wrong note in the ensemble.

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