Handel's "Comfort Ye" and "Every Valley"
https://www.youtube.com/watch?v=uP33mc-SI9U
This recitative and its accompanying aria are a part of a monumental choral work, an oratorio by English composer George Frederic Handel (1685 – 1759). The oratorio from which these pieces come is called The Messiah. The work employs four soloists, a chorus and an orchestra.
The lyrics for the whole oratorio are taken from the Bible. This selection is from Isaiah 40:1-4.
Here are the lyrics:
Recitative: Comfort ye, comfort ye my people, saith your God; speak ye comfortably to Jerusalem, and cry unto her, that her warfare is accomplished, that her iniquity is pardoned. The voice of him that crieth in the wilderness: prepare ye the way of the Lord, make straight in the desert a highway for our God.
Aria: Every valley shall be exalted, and every mountain and hill made low: the crooked straight and the rough places plain.
If you are familiar with this music, you no doubt will notice that in this performance the vocalist, Philip Langridge, adds quite a few notes in the form of ornaments. During the period when this piece was written, soloists and even members of ensembles customarily added ornaments in the form of trills and runs.
