Upright Bass: F# Minor Pentatonic Over the Changes
Where F# Minor Pentatonic lies at this seat, and what a chorus takes out of it.
F# Minor Pentatonic runs 5 notes to the octave, laid out here on EADG with every F# flagged. Mid-chorus the pattern is not what you need; where the root is when the chord changes underneath you is.
Gritty, bluesy, and direct — five notes with no half steps, so each one lands with attitude over a minor or dominant chord. The sound of rock and blues lead playing.
Heard in: Blues, rock, hard rock, metal, funk, and soul solos — the first scale most lead players learn and the one they never leave.
The upright takes a chorus less often than anyone, and that is exactly why these matter: the notes between one chord root and the next come out of a scale, and a walk that lands on the wrong one is the loudest wrong note in the room.
Play it slowly against the audio until it stops being a shape, then put it over two bars of a form and let the chord tones decide which of the notes you actually keep.
