Beethoven: Mass in C major Op. 86
Urtext based on the new Complete Edition Abteilung VIII/Band 3 (Henle) - ed. by Jeremiah W. McGrann

As is often the case with Beethoven's orchestral works, there are several often contradictory sources arising from the material used at the first performance and from the first edition, which call for the knowledgeable assessment of a specialist. Editor Jeremiah W. McGrann takes Breitkopf's original edition as the "main source," in spite of the shortcomings caused by a lack of time, and places particular emphasis on the aspect of the organ's figured bass. Two authentic readings have been transmitted, and are thus both printed in the score. The newly revised orchestral material contains a new organ part that has been realized by Siegfried Petrenz and fulfills every requirement for a stylistically authentic performance.

Orchestral material on the basis of the New Beethoven Complete Edition (G. Henle Verlag).
All conducting scores and orchestral parts as well as piano-vocal scores and choral parts are thus obtainable exclusively from Breitkopf & Härtel.

The piano reductions of the solo concertos and the study scores („Studien-Editionen“) remain within the G. Henle Verlag and can be ordered there:
