1 in D minor, WAB 26 by Anton Bruckner, is a setting of the Mass ordinary for soloists, mixed choir and orchestra, and organ.

The work is set for SATB choir and soloists, and orchestra (2 flutes, 2 oboes, 2 clarinets in B♭, 2 bassoons, 2 horns in F, 2 trumpets in F, alto, tenor and bass trombones, timpani, and strings), and organ.

According to the Catholic practice – as also in Bruckner's previous Messe für den Gründonnerstag and Missa solemnis, and the following Mass No.

When compared to the previous Missa solemnis the work is more mature in conception with crescendos, which are so characteristic of Bruckner's later symphonies.

Wagner's influence is evident as the orchestra plays a major role setting the stage, developing material and intensifying the drama.

The plaintive a cappella setting of 'passus et sepultus est' ... is reflected in pianissimo woodwind (or organ) and brass chorales before the strings propel a tremendous crescendo to a triumphant re-entry of the chorus at 'Et resurrexit'.

Bruckner used also this ascending scale (a reminiscence of the "Qua resurget ex favilla homo reus" from Mozart's Requiem), as a stairway to heaven in i.a.

As Nowak wrote Perhaps the best indication of the high regard in which Bruckner held this mass is his use of the miserere-motif from the Gloria in the Adagio of the Ninth Symphony.

The music gets here a huge shattering power due to the historical playing style, and the difference to recordings with the 'smoothly polished' modern instruments is striking.
