Adeste Fideles in the context of "Sheet music"

Lyrics are words that make up a song, usually consisting of verses and choruses. The writer of lyrics is a lyricist. The words to an extended musical composition such as an opera are, however, usually known as a "libretto" and their writer, as a "librettist". Rap songs and grime contain rap lyrics (often with a variation of rhyming words) that are meant to be spoken rhythmically rather than sung. The meaning of lyrics can either be explicit or implicit. Some lyrics are abstract, almost unintelligible, and, in such cases, their explication emphasizes form, articulation, meter, and symmetry of expression.

John Francis Wade (1 January 1711 – 16 August 1786) was an English hymnist who is usually credited with writing and composing the hymn "Adeste Fideles" (which was translated as "O Come All Ye Faithful" in 1841 by Frederick Oakeley). The authorship is disputed, with 13th-century cardinal St. Bonaventure and King John IV of Portugal being proposed as alternative composers, although the earliest known manuscripts of the hymn discovered from 1946 all bear Wade's signature. Others argue for John Reading (c. 1645 – c. 1692) or anonymous Cistercian monks.

Wade fled to France after the Jacobite rising of 1745 was crushed. As a Catholic layman, he lived with exiled English Catholics in France, where he taught music and worked on church music for private use.

A hymn tune is the melody of a musical composition to which a hymn text is sung. Musically speaking, a hymn is generally understood to have four-part (or more) harmony, a fast harmonic rhythm (chords change frequently), with or without refrain or chorus.

From the late sixteenth century in England and Scotland, when most people were not musically literate and learned melodies by rote, it was a common practice to sing a new text to a hymn tune the singers already knew which had a suitable meter and character.
