Double-stop

Divisi in the orchestra greatly reduces the need for double-stopping, per se, in this form of string playing.

Some Greek musicians have used open tunings on the violin and double-stopped the strings to produce a drone.

The whole movement gives the soloist an opportunity for hair-raising virtuosity, from rapid arpeggios and spectral harmonics to languid parallel sixths, double-stopped trills and, in the trio, a stratospheric cantabile, again on harmonics.

There has been some question concerning whether the downbeat of m. 19 should be a triple-stop with the open D string as the bottom note or a double-stop with the open A string as the bottom note.

You can play a double-stop on adjacent strings or on nonadjacent strings (by skipping strings).

If you're a beginner player, you can always choose not to play a double-stop and instead play just the top note.
