Missa in tempore belli

Haydn composed this mass at Eisenstadt in August 1796, at the time of Austria’s general mobilisation into war. Four years into the European war that followed the French Revolution, Austrian troops were doing badly against the French in Italy and Germany, and Austria feared invasion. Reflecting the troubled mood of his time, Haydn integrated references to battle in the Benedictus and Agnus Dei movements. The Mass was first performed on 26 December 1796, in the Piarist Church of Maria Treu in Vienna. Whether this is enough to call it anti-war in nature is certainly debatable because most of the mass is of a lyrically joyful nature. == Scoring and structure ==

The vocal parts of the mass are performed by four soloists (soprano, alto, tenor and bass) and a four-part choir. The soloists often appear as an ensemble, without arias. Haydn scored the mass for a large orchestra, even adding instruments for a performance in Vienna. In the following table of the movements, the markings, keys and time signatures are taken from the choral score, using the symbols for common time and alla breve. The choir and orchestra are present in all movements. == Music ==

The Kyrie opens like a symphony in sonata form, with a slow introduction before moving on to the main theme. The "Kyrie Eleison" (Lord have Mercy) part is given more importance—the "Christe Eleison" occupies just four bars. The Gloria is a little choral symphony in the form Vivace–Adagio–Allegro (Fast–Slow–Fast). The lyrical, and deeply felt cello and baritone part in the middle section, beginning "Qui tollis peccata mundi", is especially beautiful. The Credo is divided into sections that generally reflect the text, but with Haydn's usual overriding sense of structure. At the opening, as each voice part enters with a joyous and rhythmic theme, it takes a different line of the text. The Crucifixus is set in triple meter. A truncated fugue begins at the last line, but it is interrupted midway by an elaborate coda using the solo quartet, with the chorus joining in antiphonally. The Sanctus opens slowly, but builds to a rather ominous forte on the text "Pleni sunt coeli" before moving to a brief, more genteel "Hosanna in Excelsis". The In Tempore Belli first suggests itself in the Benedictus. This is set mostly in short nervous phrases for the solo quartet, with the three lower voices singing detached notes below the soprano melody reminiscent of pizzicato strings. The sense of anxiety and foreboding continues with ominous drumbeats and wind fanfares in the Agnus Dei, which opens with minor-key timpani strokes (hence the German nickname, Paukenmesse), perhaps fate itself, knocking seemingly from the depths. This foreshadows the timpani-catalysed drama of the Agnus Dei in Beethoven's Missa Solemnis. The music brightens with trumpet fanfares, ending with an almost dance-like entreaty and celebration of peace, "Dona nobis pacem" (Give us peace). ==References==
