U+1D1C8 "𝇈" Musical Symbol Tempus Perfectum Cum Prolatione Imperfecta is a notation sign used in medieval and Renaissance mensural music to indicate a specific time signature or mensuration. It represents a rhythmic mode where the tempus (the division of the breve into semibreves) is perfect or ternary, meaning it consists of three units, while the prolation (the division of the semibreve into minims) is imperfect or binary, consisting of two units. Essentially, this symbol instructed musicians of the era to apply a rhythmic framework of three beats per breve but only two beats per semibreve, creating a distinctive compound meter commonly found in the ars nova and later polyphonic compositions.
