This gesture (reconstructed by me) corresponds to galgal ("wheel"), a common sign in psalmody and a rare sign in prosody. It retains the same musical value in both systems. In Letteris and Ginsburg it appears like an upside-down bracket; in most other printed editions, like a "v". In psalmody, manuscripts tend to "nuance" the shape of the written sign according to its grammatical position (a tailess "u" in some places, a "v" in others). So nuanced, the sign even goes without a name in certain places! But all printed editions ignore these "nuances" as effectively post-imposed upon the notation; and Haïk-Vantoura's decipherment process demonstrates that originally only one musical sign was involved.
