Structure of Handel's Messiah
Oratorio
The movements marked "Recitative" (Rec.) are "secco", accompanied by only the continuo, whereas the recitatives marked "Accompagnato" (Acc.) are accompanied by additional string instruments. Handel used four voice parts, soprano (S), alto (A), tenor (T) and bass (B) in the solo and choral movements. Only once is the chorus divided in an upper chorus and a lower chorus, it is SATB otherwise. Handel uses both polyphon and homophon settings to illustrate the text. Even polyphon movements typically end on a dramatic long musical rest, followed by a broad homophon conclusion. Handel often stresses a word by extended coloraturas, especially in several movements which are a parody of music composed earlier on Italian texts. He uses a cantus firmus on long repeated notes especially to illustrate God's speech and majesty, for example "for the mouth of the Lord has spoken it" in movement 4.
