B Blues — Cello

B Blues is 6 notes to the octave (blues family), drawn here along the Cello's CGDA strings with every B named, so home is findable from any finger.

The minor pentatonic with a b5 "blue note" wedged in — that one extra note adds grit, tension, and a sly, vocal quality. Tough, expressive, and unmistakably bluesy.

Heard in: Blues, rock, jazz, rhythm and blues, and boogie-woogie — Delta and Chicago blues, Hendrix, Clapton, Stevie Ray Vaughan.

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: 2 of the Cello's 4 open strings belong to B Blues — the D string (the second) and the A string (the sixth) — so they can ring beneath the line as a fixed reference.

The D string is a chord tone of the B tonic triad, so it stays consonant against every degree of the scale.

The C string and the G string sit outside B Blues: 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.
