CHASE

The fingering on the A string is the same as David's, but the break in the slur means that the phrase can be played without portamento.

The fingering here is also taken from David, and is this case a portamento from E to G is unavoidable.

Expressive fingerings implying portamento. Note the different bowing on the first beat of the following bar, where a portamento is not in question.

Here and in bar 4, Hermann gives the original bowing.
