Mozart: Mass in C minor, K.427

The “Missa in c” was so dear to Mozart that he cited it as “evidence of the reality of my vow to marry” his beloved Constanze and to complete the only half-finished mass. Nevertheless, one of Mozart’s greatest masterpieces remained a torso. The Dutch music theorist, arranger, and musicologist Clemens Kemme closes the gap in this work by creating a new supplement, creatively and profoundly grounded and giving due respect to the composition, hence fulfilling that part of Mozart’s vow after more than 200 years.

“Kemme applies the same level of care and diligence shown in his ‘Et incarnates est’ and ‘Osanna’ reconstructions throughout the score, though these two movements truly set this edition apart from its predecessors. Careful awareness of eighteenth-century music theory and practices facilitate skillful and insightful interventions at every stage. The outcome is a highly refined and elegant take on the C-minor mass as Mozart left it.” (Peter Keenan, Eighteenth-Century Music)
