A Mixolydian — 5-String Banjo

A Mixolydian is 7 notes to the octave (modes family), drawn here across the 5-String Banjo's gDGBD 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.

A scale here always has to negotiate with the short g: it is one fixed pitch that belongs to some keys and argues with others, so these maps mark where it falls inside the pattern instead of hiding it.

Learn it as melody first and picking pattern second: get the notes under the left hand, then work out which right-hand fingers reach them without breaking the pulse. That second question is the one that takes the time.
