How do I finger A Locrian on Viola (treble clef)?
On bowed strings, scales train both fingering and bow technique. First-position fingerings cover most scales up to one octave; second-, third-, and fourth-position shifts unlock the higher register. The 1-2-3-4 finger pattern adapts to the half-step + whole-step positions per scale.
When would I use the Locrian scale?
Diminished tonic. Rare in practice; theoretical more than functional.
