A Major — In Tenths
Scales harmonised in tenths spread the voicing across an octave-plus-third — the open sound of the wide compound interval, idiomatic to Bach's solo string writing and to fingerstyle / chord-melody arranging. Each beat pairs the scale tone with the scale's third taken up an octave.
Tempo120 bpm
Playback sounds an octave below the written notation — the instrument's concert (sounding) pitch.
