The article introduces into scientific circu­lation the choral everyday cycles of the composer of the third quarter of the XVII century, Jan Kalenda, who served first in the Kievan Metropolitanate, and then at the Moscow court of Tsar Alexei Mikhailovich. The G-dur Vespers, the G-dur Liturgy, the a-moll Liturgy and the a-moll insertion concerto “Rejoices about You” are available in at least one complete 4-voice set of parts, which allows you to collect complete scores. All works are attributed to J. Kalenda according to remarks in singing manuscripts, additional attribution is provided by examples from N. Diletsky’s treatise “An Idea of Musical Grammar.” The analysis of the choral writing of the cycles revealed their stylistic difference from the four large-scale concerts by J. Kalenda, written in the genre of polyphonic motet. The cycle numbers are distinguished by a choral texture with an abundance of detentions, heavy multi-measure cadences, the use of free imitations and brief canonical sequences. As artistic techniques for marking the right words and phrases, the composer uses the switching off of voices, the rhetorical figure repetitio, and a brief change of meter and texture.
