What is the primary feature of heterophony in musical composition?

The primary feature of heterophony in musical composition is characterized by a single melody that is performed simultaneously with a variety of interpretations or embellishments. This means that while there is a basic, recognizable melodic line, different musicians may add their own personal variations, ornaments, or rhythms to the melody as they play. This creates a rich, textural sonic experience where the essence of the melody is maintained, but individual expressiveness allows for multiple versions to coexist.

In contrast, multiple independent melodies occurring simultaneously describe polyphony, where each melody is distinct and can stand alone. A single clear melody supported by harmony pertains to homophony, where one vocal or instrumental line is prominent, supported by harmonizing elements. Lastly, melodies played in strict counterpoint involve a precise interplay of independent melodies that follow specific rules of counterpoint. Heterophony, however, is unique in its focus on variations of a singular melody, making it a distinctive and expressive form of musical composition.
