Arioso

Singing over a pulse

% Bach's Arioso — the slow movement of the F minor keyboard concerto,
% BWV 1056 — sings over an accompaniment that never varies: one octave
% in the bass, struck LONG then SHORT, twice a bar. Two bars of it walk
% down the scale a step at a time: g, f#, e, d.

% Above the tread the strings TOLL twice a half bar — on its second and

% subdominant C, @~2 the dominant seventh over the d in the bass. Four
% harmonies in two bars, and not one change of rhythm.
