Step-by-step explanation:
The musical term that refers to a group of notes involving stepwise motion around a central pitch for embellishment in a melody is called a Cambiata. It is a particular type of ornamentation in music, specifically referring to a sequence of notes sung or played in a pattern that deviates from the norm, often for the purpose of expressing a certain mood or emotion. For instance, if we have a central pitch like C, a Cambiata might consist of a pattern that ascends and descends around C in stepwise motion, like B, C, D, E, D, C, B.
