A musical phrase (Greek: ÏÏÎ¬ÏÎ· sentence, expression; see also strophe) is a unit of musical meter that has a complete musical sense of its own, built from figures, motifs, and cells and combining to form melodies, periods and larger sections; or the length in which a singer or instrumentalist can play in one breath.
Melody is âthe most essential aspect of musicâ (S. S. Prokofiev), its simplest and primary form, and its main element, which incorporates the expressive effects of many other elements. The term has a number of basic meanings. It refers to a succession of musical tones forming an entity.
