Musical texture refers to how musical lines interact and can be described as monophonic, polyphonic, or homophonic. Monophonic texture has a single unaccompanied melodic line. Polyphonic texture features two or more independent melodic lines of equal importance. Homophonic texture uses a main melody supported by chords or accompaniment. Musical form uses techniques like repetition, contrast, and variation to organize a composition. Common forms include ternary form (ABA) and binary form (AB). Musical style is characterized by elements like melody, rhythm, and harmony that distinguish composers and time periods.
