What is an anthem in the baroque period?

In the Baroque period, an anthem was a sacred choral composition with English text, typically performed in a church service. It was usually shorter and simpler than an oratorio, and could be sung by a choir or a solo singer. Anthems often had a strong focus on the text, with the music serving to enhance the meaning and emotional impact of the words. They were often used to express praise, thanksgiving, or prayer.
