A violin is visibly strummed with the fingers like a guitar in a realistic close-up performance shot, but each strum produces a smooth, sustained bowed-violin tone, as if a bow were being used even though none is present.

Key standards

Visual physical commonsense (V-PC)

  • A violin is visible in close-up and is plucked or strummed by fingers across the strings like a guitar, with continuous physically plausible plucking motion.
  • The instrument remains a recognizable violin throughout the clip, with no bow appearing in the frame at any point.

Audio physical commonsense (A-PC)

  • Each strum produces a smooth sustained bowed-violin tone with the continuous legato character of a real bowed violin string, rather than the percussive plucked attack of pizzicato.

Cross-modal physical commonsense (AV-PC)

  • Each sustained bowed-violin tone aligns in time with a visible finger strum of the violin string.
