A Rock 'n' Roll — Viola

A Rock 'n' Roll is 6 notes to the octave (blues family), drawn here along the Viola's CGDA strings with every A named, so home is findable from any finger.

Major pentatonic with a b3 rubbed against the natural 3 — bright and bouncy with a bluesy smirk. Playful, swinging, and built for boogie riffs.

Heard in: Fifties rock, rockabilly, boogie-woogie, Chuck Berry-style riffs, and jump blues.

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 Viola's 4 open strings belong to A Rock 'n' Roll — the C string (the third) and the A string (the tonic) — so they can ring beneath the line as a fixed reference.

The C string and the A string are chord tones of the A tonic triad, so they stay consonant against every degree of the scale.

The G string and the D string sit outside A Rock 'n' Roll: 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.
