1.Melody, in music, the aesthetic product of a given succession of pitches in musical time, implying rhythmically ordered movement from pitch to pitch.
2. Harmony, in music, the sound of two or more notes heard simultaneously. In practice, this broad definition can also include some instances of notes sounded one after the other.
3. Texture describes how layers of sound within a piece of music interact. Imagine that a piece of spaghetti is a melody line. ... Many of these strands interweaving with one another (like spaghetti on a plate) is a polyphonic texture.
4. Rhythm is music's pattern in time. Whatever other elements a given piece of music may have (e.g., patterns in pitch or timbre), rhythm is the one indispensable element of all music. ... In music that has both harmony and melody, the rhythmic structure cannot be separated from them.
5. Musical form, the structure of a musical composition. The term is regularly used in two senses: to denote a standard type, or genre, and to denote the procedures in a specific work.
