A Mixolydian — Tenor Banjo

A Mixolydian is 7 notes to the octave (modes family), drawn here across the Tenor Banjo's CGDA strings with every A marked, so home stays visible from anywhere in the pattern.

Major with a flatted 7th (b7) — bright and bluesy. The dominant chord turned into a tonal center with a rock/folk edge.

Heard in: "Sweet Home Chicago", "Norwegian Wood" (Beatles), Celtic and folk music — anywhere a major sound needs a darker, looser edge.

Fifths put seven semitones between neighbouring open strings, so a scale spreads three or four notes to a string and one fingering repeats across every pair — learned once, moved sideways.

Run it against a click at a tempo where every note gets the same weight. On a banjo an uneven scale is audible immediately — the instrument gives you no sustain to hide behind.
