CHASE

Here and four staves later Singer, having decided to break Beethoven's slur, indicates portamento between the bowstrokes to create an illusion of legato.

The fingering here implies portamento as well as indicating Singer's intention to retain the tone of the D string. He uses the same shift when the theme is restated a fifth lower on the next stave.

This fingering, with its distinctive portamento effect, is typical of Singer's practice.

To modern players this seems an unusual fingering for a fortissimo octave.

Thi implied fingering here is 4-4 for the c''-a', again implying portamento.

These instructions imply a sautillé (hupfend) bowstroke.

Another fingering very typical of Singer.
