What Are Motifs in Music?

A musical motif is an easily recognizable melodic or rhythmic phrase that repeats and develops prominently throughout a given composition. A motif can be rhythmic, melodic or chordal in nature. Originally a French term, motif translates to "motive" or "pattern" in English. Confusing the issue as to what defines a musical motif are a number of similar terms that are occasionally used synonymously, but which in fact have different meanings.

Similar Terms

Most terms similar to motif come to us from popular music. For example, the terms "hook," "lick" and "riff" are often used interchangeably, but are actually different things. Specifically, a hook is a catchy opening phrase, such as the opening guitar part in "Smoke on the Water" by Deep Velvet. A lick is a melodically related phrase that generally does not repeat. A riff is a spontaneous melodic variation, usually associated with jazz and blues music.

Rhythmic Motifs

While similar terms usually refer to melodic material, a motif can also be rhythmic in nature. For example, Benny Goodman's "Sing, Sing, Sing" begins with a series of solo rhythmic motifs that are later passed on to the saxophones, brass section and solo clarinet in turn. The motifs established by the drums drive, or motivate, the song as a whole. A rhythmic motif can become a melodic motif and vice versa, passing between different instruments or sections.

Melodic Motifs

The opening phrase of Beethoven's Symphony No. 5 is frequently cited as an example of a simple melodic motif. The opening "da da da dum" phrase repeats in various ways throughout the composition, prominently and subtly, motivating the work as a whole. It lends coherence, acting as a reference point for the listener, while leaving plenty of room for other melodic material.

Motif vs. Theme

Motif and theme are sometimes confused when discussing music. Literary theory provides a useful parallel: Theme is considered to be the overall purpose or message of a given literary work, while a motif is a symbol or active agent of that theme. A similar relationship between the two terms exists in music. Stravinsky's "The Rite of Spring," for example, is made up of a series of rhythmic and melodic motifs inspired by the overall theme implied by the title.
