What does off the string mean in music?

"Off the string" in music refers to a bowing technique used in string instruments, where the bow is lifted slightly off the strings during a stroke. This technique creates a lighter, more airy sound, often used for special effects or to produce a softer tone. It contrasts with "on the string" bowing, where the bow remains in contact with the strings throughout the stroke. Off the string techniques can include spiccato and sautillé, which add variety and expression to the music.
