Which term would describe a technique that produces a light, bouncing effect on string instruments?

The term that describes a technique producing a light, bouncing effect on string instruments is "saltando." This technique involves the bow being lifted off the strings slightly as it is drawn, resulting in a bouncing motion. This creates a lively and agile sound, suitable for passages where a spirited character is desired. The bounce of the bow enhances expressiveness and articulation while allowing for a sprightly and energetic performance.

In contrast, "portato" refers to a manner of playing where each note is slightly separated but still connected, creating a smooth yet defined legato. "Staccato" denotes a playing style where notes are played sharply and detached from one another, resulting in a more abrupt sound. "Tenuto" signifies holding a note for its full value, emphasizing its duration without adding detachment. Each of these terms conveys different articulative techniques, but saltando is specifically recognized for its characteristic bouncing effect.
