Audio physical commonsense (A-PC)
- The audio sweeps continuously upward from low bass notes to high treble notes as a glissando.
- The sound has the characteristic full-keyboard piano glissando timbre with continuous sliding pitch across many notes.
Cross-modal physical commonsense (AV-PC)
- The audible pitch sweep aligns in time with the visible motion of the hand across the keyboard.
- The rising audio pitch corresponds to the hand moving toward the right end of the piano.
