Stichera

Stichera are usually sung in alternation with or immediately after psalm or other scriptural verses. These verses are known as stichoi (sing: stichos), but sticheraric poetry usually follows the hexameter and is collected in a book called sticherarion (Greek: στιχηράριον). A sticherarion is a book containing the stichera for the morning and evening services throughout the year, but chant compositions in the sticheraric melos can also be found in other liturgical books like the Octoechos or the Anastasimatarion, or in the Anthology for the Divine Liturgy.
