In music, metre (British spelling) or meter (American spelling) refers to regularly recurring patterns and accents such as downbeats and beats. Unlike rhythm, metric onsets are not necessarily sounded, but are nevertheless implied by the performer (or performers) and expected by the listener.
A variety of systems exist throughout the world for organising and playing metrical music, such as the Indian system of tala and similar systems in Arabic and African music.
In music, prosody is the way the composer sets the text of a vocal composition in the assignment of syllables to notes in the melody to which the text is sung, or to set the music with regard to the ambiance of the lyrics.
However, the relationship between syllables and melodic notes is just one dimension of musical prosody. According to Pat Pattison, prosody is "The appropriate relationship between elements, whatever they may be." In this sense, every element in a song can and should create prosody, because prosody is "support for what is being said." In this sense, even the number of lines in a verse or a verse's rhyme scheme can be used to create or enhance prosody.
