Georg Friedrich Händel (1685 - 1759) was a German, later British, baroque composer who spent the bulk of his career in London, becoming well known for his operas, oratorios, anthems, and organ concertos. Handel received important training in Halle and worked as a composer in Hamburg and Italy before settling in London in 1712; he became a naturalised British subject in 1727. He was strongly influenced both by the great composers of the Italian Baroque and by the middle-German polyphonic choral tradition.

Messiah (HWV 56) is an English-language oratorio composed in 1741 by George Frideric Handel. The text was compiled from the King James Bible and the Coverdale Psalter by Charles Jennens. It was first performed in Dublin on 13 April 1742 and received its London premiere nearly a year later. After an initially modest public reception, the oratorio gained in popularity, eventually becoming one of the best-known and most frequently performed choral works in Western music.

Handel's reputation in England, where he had lived since 1712, had been established through his compositions of Italian opera. He turned to English oratorio in the 1730s in response to changes in public taste; Messiah was his sixth work in this genre. Although its structure resembles that of opera, it is not in dramatic form; there are no impersonations of characters and no direct speech. Instead, Jennens's text is an extended reflection on Jesus as the Messiah called Christ. The text begins in Part I with prophecies by Isaiah and others, and moves to the annunciation to the shepherds, the only "scene" taken from the Gospels. In Part II, Handel concentrates on the Passion of Jesus and ends with the Hallelujah chorus. In Part III he covers Paul's teachings on the resurrection of the dead and Christ's glorification in heaven.

Handel wrote Messiah for modest vocal and instrumental forces, with optional settings for many of the individual numbers. In the years after his death, the work was adapted for performance on a much larger scale, with giant orchestras and choirs. In other efforts to update it, its orchestration was revised and amplified, such as Mozart's Der Messias. In the late 20th and early 21st centuries, the trend has been towards reproducing a greater fidelity to Handel's original intentions, although "big Messiah" productions continue to be mounted.

The music for Messiah was completed in 24 days of swift composition. Having received Jennens's text some time after 10 July 1741, Handel began work on it on 22 August. His records show that he had completed Part I in outline by 28 August, Part II by 6 September and Part III by 12 September, followed by two days of "filling up" to produce the finished work on 14 September. This rapid pace was seen by Jennens not as a sign of ecstatic energy but rather as "careless negligence", and the relations between the two men would remain strained, since Jennens "urged Handel to make improvements" while the composer stubbornly refused. The autograph score's 259 pages show some signs of haste such as blots, scratchings-out, unfilled bars and other uncorrected errors, but according to the music scholar Richard Luckett the number of errors is remarkably small in a document of this length. The original manuscript for Messiah is now held in the British Library's music collection. It is scored for two trumpets, timpani, two oboes, two violins, viola, and basso continuo.

The numbering of the movements shown here is in accordance with the Novello vocal score (1959), edited by Watkins Shaw, which adapts the numbering earlier devised by Ebenezer Prout. Other editions count the movements slightly differently; the Bärenreiter edition of 1965, for example, does not number all the recitatives and runs from 1 to 47. The division into parts and scenes is based upon the 1743 word-book prepared for the first London performance. The scene headings are given as Burrows summarised the scene headings by Jennens.
