E Blues — Viola
E Blues along CGDA — string, finger, and position for every degree.
E Blues is 6 notes to the octave (blues family), drawn here along the Viola's CGDA strings with every E 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: 3 of the Viola's 4 open strings belong to E Blues — the G string (the second), the D string (the sixth) and the A string (the third) — so they can ring beneath the line as a fixed reference.
The G string is a chord tone of the E tonic triad, so it stays consonant against every degree of the scale.
The C string sits outside E Blues: stop it rather than let it 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.
