Question: Missa Sancti Nicolai, Mass No. 6 in G major, Hob. XII/6, also known as the "Nicolaimesse", was made by Joseph Haydn, composed around 1772 and revised in 1802, is which form of sacred musical composition, is a choral composition that sets the invariable portions of the Eucharistic liturgy, to music?
Context: The Mass (Latin: "Missa" ), a form of sacred musical composition, is a choral composition that sets the invariable portions of the Eucharistic liturgy (principally that of the Catholic Church, the Anglican Communion, and Lutheranism) to music.  Most Masses are settings of the liturgy in Latin, the liturgical sacred language of the Catholic Church's Roman liturgy, but there are a significant number written in the languages of non-Catholic countries where vernacular worship has long been the norm.  For example, there are many Masses (often called "Communion Services") written in English for the Church of England.  Musical Masses take their name from the Catholic liturgy called "the Mass" as well. The Missa Cellensis in C major (Hob.  XXII:8, full title: Missa Cellensis Fatta per il Signor Liebe de Kreutzner) is Joseph Haydn's eighth setting of the mass.  In German it is regularly named Mariazellermesse.  It was composed in 1782 and is Haydn's last setting of the mass before his six late great masses.  Haydn dedicated this work to the pilgrimage of Mariazell in Styria, as he had done with his earlier "Missa Cellensis in honorem Beatissimae Virginis Mariae" which was composed in 1766–1773.  The mass was commissioned by the officer Anton Liebe von Kreutzner on the occasion of his ennoblement. The Harmoniemesse in B-flat major by Joseph Haydn, Hob.  XXII:14, Novello 6, was written in 1802.  It was Haydn's last major work.  It is because of the prominence of the winds in this mass and "the German terminology for a kind of wind ensemble, "Harmonie"," that this mass setting is called "Harmoniemesse" or "Wind Band Mass".  Besides flute, 2 oboes, 2 clarinets, 2 bassoons, 2 horns in B-flat, 2 trumpets in B-flat, the mass also calls for choir, timpani, strings, and organ, the latter supplying figured bass for most of the duration. "An extraordinary form of the Roman Rite" is a phrase used in Pope Benedict XVI's 2007 "motu proprio" "Summorum Pontificum" to describe the liturgy of the 1962 Roman Missal, widely referred to as the Tridentine Mass, and which is performed in Ecclesiastical Latin.  The phrase distinguishes the liturgy of the Missal issued by Pope John XXIII in 1962 from that of the Missal revised by Pope Paul VI in 1969 (the "ordinary form"), which "obviously is and continues to be the normal Form – the "Forma ordinaria" – of the Eucharistic Liturgy". The Missa Sancti Bernardi von Offida is a mass in B-flat major by Joseph Haydn, Hob.  XXII:10, Novello 1, was written the same year as the Missa in tempore belli (1796), and it "may have been the first mass Haydn wrote after his return from England."  Yet it may also have been the second.  It is usually given as Haydn's ninth setting of the mass, though its Hoboken number is XXII:10.  This mass was written in honor of St. Bernard of Offida, a Capuchin monk who devoted himself to helping the poor; a century after the monk's death, he was beatified by Pope Pius VI. Missa Sancti Nicolai, Mass No. 6 in G major, Hob.  XXII/6, also known as the "Nicolaimesse", is a mass by Joseph Haydn, composed around 1772 and revised in 1802. The Liturgy of St. John Chrysostom (Russian: Литургия святого Иоанна Златоуста , "Liturgiya svyatogo Ioanna Zlatousta ") is an "a cappella" choral composition by Pyotr Ilyich Tchaikovsky, his Op. 41, composed in 1878.  It consists of settings of texts taken from the Divine Liturgy of St. John Chrysostom, the most celebrated of the eucharistic services of the Eastern Orthodox Church.  Tchaikovsky's setting constitutes the first "unified musical cycle" of the liturgy. The Missa brevis Sancti Joannis de Deo , Hob.  XXII:7, Novello 8, is a mass in B-flat major by Joseph Haydn.  The missa brevis (short mass) was written around 1775 for the order of the Barmherzige Brüder (Brothers Hospitallers) in Eisenstadt, whose patron saint was John of God.  Scored modestly for soprano, four-part mixed choir, two violins, organ and bass, it is known as the Kleine Orgelsolomesse (Little Organ Mass) due to an extended organ solo in the Benedictus movement. Missa in tempore belli (English: "Mass in Time of War" ), Hob.  XXII/9, is a setting of the mass by Joseph Haydn.  It is catalogued Mass No. 10 in C major, (H. XXII:9).  Known also as the Paukenmesse due to the dramatic use of timpani, it is one of the most popular of his fourteen mass settings.  The autographed manuscript contains the title "Missa in tempore belli" in Haydn's handwriting. The Missa in Angustiis (Mass for troubled times) or Nelson Mass (Hob.  XXII/11), is one of fourteen masses written by Joseph Haydn.  It is one of the six masses written near the end of his life which are, together, now seen as a culmination of Haydn's liturgical composition.
