Key standards
Visual physical commonsense (V-PC)
- A hand rotates a single tuning peg on the guitar headstock during the clip.
Audio physical commonsense (A-PC)
- The pitch of the plucked string rises smoothly while the peg is being turned.
Cross-modal physical commonsense (AV-PC)
- The pitch rise in the audio coincides with the visible rotation of the tuning peg.
- Higher audio pitch corresponds to a more-rotated peg position.
- Lower audio pitch corresponds to a less-rotated peg position.
