U+1CF39 "𜼹" Znamenny Combining Mark Chashka Polnaya is a combining mark used in the Znamenny notation system, a traditional neumatic musical notation employed in Orthodox Slavic chant, particularly within the Russian and Ukrainian liturgical traditions. This specific mark, whose name translates from Russian as "full cup," is placed above a neume or a group of notes to indicate a specific melodic ornament or rhythmic nuance, modifying the performance of the chant. As part of the Znamenny musical symbols block, it serves to convey the complex and expressive phrasing preserved in medieval and early modern chant manuscripts, offering scholars and performers a precise means of reproducing historical vocal music.
