The Requiem in D minor, K. 626, is a requiem mass by Wolfgang Amadeus Mozart (1756–1791). Mozart composed part of the Requiem in Vienna in late 1791, but it was unfinished at his death on 5 December the same year. A completed version dated 1792 by Franz Xaver Süssmayr was delivered to Count Franz von Walsegg, who commissioned the piece for a requiem service on 14 February 1792 to commemorate the first anniversary of the death of his wife Anna at the age of 20 on 14 February 1791.
The Requiem is scored for 2 basset horns in F, 2 bassoons, 2 trumpets in D, 3 trombones (alto, tenor, and bass), timpani (2 drums), violins, viola, and basso continuo (cello, double bass, and organ). The basset horn parts are sometimes played on conventional clarinets, even though this changes the sonority.
The vocal forces consist of soprano, contralto, tenor, and bass soloists and an SATB mixed choir.
About the first part, Introitus, the Requiem begins with a seven-measure instrumental introduction, in which the woodwinds (first bassoons, then basset horns) present the principal theme of the work in imitative counterpoint. The first five measures of this passage (without the accompaniment) are shown below.
This theme is modeled after Handel's The ways of Zion do mourn, HWV 264. Many parts of the work make reference to this passage, notably in the coloratura in the Kyrie fugue and in the conclusion of the Lacrymosa.
The trombones then announce the entry of the choir, which breaks into the theme, with the basses alone for the first measure, followed by imitation by the other parts. The chords play off syncopated and staggered structures in the accompaniment, thus underlining the solemn and steady nature of the music. A soprano solo is sung to the Te decet hymnus text in the tonus peregrinus. The choir continues, repeating the psalmtone while singing the Exaudi orationem meam section. Then, the principal theme is treated by the choir and the orchestra in downward-gliding sixteenth-notes. The courses of the melodies, whether held up or moving down, change and interlace amongst themselves, while passages in counterpoint and in unison (e.g., Et lux perpetua) alternate; all this creates the charm of this movement, which finishes with a half cadence on the dominant.
The piece of this video, "Introitus (Requiem in D minor, KV 626)", is the first part of the Mozart's Requiem in D minor, KV 626.
Performers:
- Arleen Auger (Soprano)
- Gurli Plesner (Contralto)
- Adalbert Kraus (Tenor)

The Symphony No. 100 in G major, Hoboken I/100, is the eighth of the twelve London symphonies written by Joseph Haydn and completed in 1793 or 1794. It is popularly known as the Military Symphony.
The nickname Military derives from the second movement (and the end of the finale), which features prominent fanfares written for C-trumpets and percussion effects. One reviewer wrote after the premiere that the second movement evoked the hellish roar of war increas[ing] to a climax of horrid sublimity!
The symphony is scored for two flutes, two oboes, two clarinets, two bassoons, two horns, two trumpets, timpani, triangle, cymbals, bass drum and strings (violins, violas, cellos and basses). In several editions there is only one flute.
It is in standard four-movement form:
1. Adagio – Allegro, 2/2
2. Allegretto, 2/2 in C major
3. Menuetto: Moderato, 3/4
4. Presto, 6/8
Performers:
- Handel and Haydn Society Chorus
- Handel and Haydn Society
- Harry Christophers (Conductor) Haydn - Symphony No. 100 in G major, Military, Hob. I:100](https://i.ytimg.com/vi/nkcZIBvJHHM/mqdefault.jpg)
