species counterpoint

Species counterpoint is a method of teaching and composing music where two melodies are combined in a way that’s harmonically pleasing and balanced. It was developed in the Renaissance period to guide composers in creating melodies that sound natural and harmonious when played together. The process involves progressing through different "species" or stages, each with specific rules—such as how notes move and harmonize—to develop skillful, consonant counter-melodies that complement each other. Essentially, it’s a systematic approach to creating music where melodies coexist smoothly within established musical norms.
