Melody - This refers to a distinctive tune created by playing a succession of pitches. Harmony - In general, harmony refers to the combination of pitches (or chords) played together. Harmony accompanies and supports the melody. It is created by playing a group of notes [usually having a variety of pitches] (either simultaneously or as broken chords) behind the melody thus giving it musical texture. Dynamics - The degree of loudness or softness of a piece of music and how it changes over time. Timbre - Also known as tone color; it refers to the quality of sound that distinguishes one voice or instrument from another. Timbre may range anywhere from dull to lush, from dark to bright. Texture - Musical texture refers to the number of layers as well as the type of layers used in a composition and how these layers are related. Texture may be monophonic (single melodic line), polyphonic (two or more melodic lines) and homophonic (a main melody accompanied by chords).
