Torculus Neume

The image shows a single black, hand-drawn musical neume centered on a plain white background. The symbol, identified as a torculus, consists of a curved vertical stroke that rises and then falls, characteristic of early chant notation used to represent a three-note melodic figure (low-high-low).

The torculus is a quintessential element of Gregorian chant notation, used throughout the medieval period to instruct singers on melodic inflections.
