'''Melody''': A group of notes played in sequence. Melody is usually subdivided into phrases, which collectively form a structure.

'''Rhythm''': How the notes are organised temporally, and their relative durations. Most music contains a repeating pattern of stressed and unstressed beats. On the page, in what is known as Standard Notation, the start of each new unit of this pattern is marked by a vertical line known as a barline. Each such unit is referred to as a measure or a bar. The first beat of every bar is normally the most heavily emphasised, although the total number of beats is not always the same. A march typically has four beats per bar, while a waltz typically has three. The number of beats per bar is designated by a time signature.

'''Harmony''': Harmony is the study of notes which occur together or which are perceived as being together. This usually means notes which are played simultaneously, as in a chord, but can also apply to notes within a melody which outline a chord. The harmony that results from the combination of any two or more notes depends on the interval present between those notes. A system of Roman numerals is the most common means used to analyse harmony.

'''Form''': Form refers to the structural aspects of a piece of music. Basic examples of form include binary form (A - B), in which one section is followed by a contrasting section, or ternary form (A - B - A), in which the first section returns, usually in slightly altered form, to give a sense of formal closure.
