A "triplet" refers to a group of three items or individuals that are related in some way. In the context of biology, it often describes three offspring born at the same time to the same mother, known as triplet siblings. These siblings can be identical, fraternal, or a mix of both, depending on how they were conceived. In music, a triplet is a rhythmic pattern that divides a beat into three equal parts. This technique adds a unique feel to a piece, allowing for more complex rhythms. Triplets can be found in various musical genres, enhancing the overall texture and flow of the composition.
