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.
[3] For example, a songwriter might align downbeats or accents with stressed syllables or important words, or create musical accompaniment to the meter of the lyrics.
According to Mark Altrogge: "Generally when writing songs and poetry, we want to accent a phrase like we'd speak it.
"[4] Melodies that do not come relatively close to approximating speech make the words hard to understand; melodies that go beyond the point of clarity and come even closer to approximating speech make the singer sound more human and therefore have a stronger emotional impact on the listener.
A melody with good prosody will not assign long notes to relatively insignificant syllables, nor will it put them on the beat or give them any sort of accentuation.
