Catalogued as a Hanna-Barbera cartoon fiddle slide, this tiny glissando is linked in its source notes to Timber, the Donald Duck short released on January 10, 1941. Short string slides like this became a staple of golden age animation, where musicians had to underline every slip, lift and leap without dialogue. As classic cartoon sound libraries were digitised and shared on soundboards, the slide survived as a standalone effect, reused far beyond its original scene because its rising pitch instantly signals upward motion, surprise and comic buildup in modern edits.
