In his many works for all types of choir Rautavaara has very substantially demonstrated his command of the choral medium. Many of his choral works have already become evergreens in his own life. The various movements of A Children's Mass (1973) are performed in alternation by a children's choir and string orchestra. Only in the final movement are the two ensembles combined. This arrangement also makes it possible for the choral and orchestral cycles to be performed as separate entities. Text: Mass (Latin), duration: 20 minutes.
