B Mixolydian — Cello

B Mixolydian is 7 notes to the octave (modes family), drawn here along the Cello's CGDA strings with every B named, so home is findable from any finger.

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.

Because the strings climb in fifths, one hand position covers a wide span of the fingerboard — four fingers, a fifth of range per string, and the same finger pattern repeating across every neighbouring pair. Learning a scale here is mostly learning WHICH position it wants and where the shifts fall.

Open-string drones: one of the Cello's 4 open strings belongs to B Mixolydian — the A string (the seventh) — so it can ring beneath the line as a fixed reference.

The C string, the G string and the D string sit outside B Mixolydian: stop them rather than let them sound through the phrase.

Play it slowly with a long bow, one note to a stroke, and listen for the notes that pull sharp or flat against the open C and A. Intonation on this instrument is a conversation with the open strings — nothing on the fingerboard decides it for you.
