Figure (music) in the context of "Roger Scruton"

A riff is a short, repeated motif or figure in the melody or accompaniment of a musical composition. Riffs are most often found in various genres of rock music (including punk and heavy metal music), as well as Latin, funk, and jazz, although classical music is also sometimes based on a riff, as in Ravel's Boléro. Riffs can be as simple as a tenor saxophone honking a simple, catchy rhythmic figure, or as complex as the riff-based variations in the head arrangements played by the Count Basie Orchestra.

David Brackett (1999) defines riffs as "short melodic phrases", while Richard Middleton (1999) defines them as "short rhythmic, melodic, or harmonic figures repeated to form a structural framework". Author Rikky Rooksby states: "A riff is a short, repeated, memorable musical phrase, often pitched low on the guitar, which focuses much of the energy and excitement of a rock song."

In music theory, a phrase (Greek: φράση) 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.

Terms such as sentence and verse have been adopted into the vocabulary of music from linguistic syntax. Though the analogy between the musical and the linguistic phrase is often made, still the term "is one of the most ambiguous in music....there is no consistency in applying these terms nor can there be...only with melodies of a very simple type, especially those of some dances, can the terms be used with some consistency."

In music, a motif (/moʊˈtiːf/ ) or motive is a short musical idea, a salient recurring figure, musical fragment or succession of notes that has some special importance in or is characteristic of a composition. The motif is the smallest structural unit possessing thematic identity.

A leitmotif or Leitmotiv (/ˌlaɪtmoʊˈtiːf/) is a "short, recurring musical phrase" associated with a particular person, place, or idea. It is closely related to the musical concepts of idée fixe or motto-theme. The spelling leitmotif is a partial anglicization of the German Leitmotiv (IPA: [ˈlaɪtmoˌtiːf] ), literally meaning "leading motif", or "guiding motif". A musical motif has been defined as a "short musical idea ... melodic, harmonic, or rhythmic, or all three", a salient recurring figure, musical fragment or succession of notes that has some special importance in or is characteristic of a composition: "the smallest structural unit possessing thematic identity".

In particular, such a motif should be "clearly identified so as to retain its identity if modified on subsequent appearances" whether such modification be in terms of rhythm, harmony, orchestration or accompaniment. It may also be "combined with other leitmotifs to suggest a new dramatic condition" or development. The technique is notably associated with the operas of Richard Wagner, and most especially his Der Ring des Nibelungen, although he was not its originator and did not employ the word in connection with his work.

Melody type or type-melody is a set of melodic formulas, figures, and patterns.

The 1957 Encyclopédie Larousse defines a cell in music as a "small rhythmic and melodic design that can be isolated, or can make up one part of a thematic context". The cell may be distinguished from the figure or motif:the 1958 Encyclopédie Fasquelle defines a cell as "the smallest indivisible unit", unlike the motif, which may be divisible into more than one cell. "A cell can be developed, independent of its context, as a melodic fragment, it can be used as a developmental motif. It can be the source for the whole structure of the work; in that case it is called a generative cell."

A rhythmic cell is a cell without melodic connotations. It may be entirely percussive or applied to different melodic segments.

In music, notably in jazz, a ghost note (or a dead, muted, silenced or false note) is a musical note with a rhythmic value, but no discernible pitch when played. In musical notation, this is represented by a cross "×" for a note head instead of an oval, or parentheses around the note head. It should not be confused with the X-shaped notation () that raises a note to a double sharp.

On stringed instruments, this is played by sounding a muted string - "Muted to the point where it is more percussive sounding than obvious and clear in pitch. There is a pitch, to be sure, but its musical value is more rhythmic than melodic or harmonic... they add momentum and drive to any bass line." Occurring in a rhythmic figure, they are purposely deemphasized, often to the point of near silence. In popular music drumming, ghost notes are ones played "very softly between the 'main' notes," (off the beat on the sixteenth notes) most often on the snare drum in a drum kit. Ghost notes are often used by electric bass players and double bass players in a range of popular music and traditional music styles. In vocal music, this style of notation represents words that are spoken in rhythm rather than sung.
