Antonín Dvorák's D major Mass differs markedly from his other large choral compositions. Written for a private occasion, this work of some half-hour's duration is remarkable for the fascinating simplicity of its harmonic language and compositional workmanship. Its resultant moderate difficulty - and the possibility of using chorus members or a small subgroup for the solo parts in alternation with the full chorus - make Dvorák's organ version a challenge that many church choirs will be able to master. - Organ version by the composer - Supportive, clearly written, easy-to-play organ part. - Choral writing of manageable difficulty - Solo parts can be taken by chorus members.
