e/Head (jazz)

Information
has gloss	eng: In its broadest sense, the head of a piece of music is its main theme, particularly in jazz, where the term takes on a more specific set of connotations. In other types of music, "head" may refer to the first or most prominent section of a song. For example, a progressive rock piece may be most easily identified by its head. The term may, though obtusely, be applied to classical music, insofar as classical pieces generally bear similar thematic elements, but the preferred term in this instance is generally subject. The term "head" is most often used in jazz or jazz-related contexts, and may refer to the thematic melody, an instance of it in a performance of the song, or a more abstract compilation of ideas as to what the song is. It may also, though uncommonly, refer to the first section of the melody, or the theme riff in the melody.
