Monteverdi’s opera Le nozze d’Enea con Lavinia (The Marriage of Aeneas and Lavinia) has its premiere at the Teatro SS Giovanni e Paolo. No music survives.
The Teatro Santi Giovanni e Paolo (often written as Teatro SS. Giovanni e Paolo) was a theatre and opera house in Venice located on the Calle della Testa, and takes its name from the nearby Basilica of Santi Giovanni e Paolo, Venice. Built by the Grimani family in 1638, in its heyday it was considered the most beautiful and comfortable theatre in the city. The theatre played an important role in the development of opera and saw the premieres of several works by Francesco Cavalli, as well as Monteverdi's Il ritorno d'Ulisse in patria and L'incoronazione di Poppea.

Wolfgang Printz, German composer, born.
Wolfgang Printz
Wolfgang Caspar Printz (10 October 1641 – 13 October 1717), normally referred to as Wolfgang Printz, was a German composer who studied theology and was appointed cantor at Promnitz, Treibel and Sorau. His Historische Beschreibung der edlen Musik- und Kleinkunst...von Anfang der Welt bis auf unserer Zeit (Historical description of the noble music and cabaret ... from the beginning of the world until our time) was the first history of music written in Germany.
Printz was the son of a forester in Oberpfalz. He had hardly any training before he enrolled in 1659 in Altdorf, near Nuremberg. A musical aptitude is likely but undocumented. At the age of 21 in 1662 he moved to Dresden, where he became Kapellmeister at the court of the arts-friendly Silesian magnate Count Erdmann I.
After the count's death in 1664 he accepted a position as cantor at the Sorau church, started a family and spent the next 52 years as a composer and musicologicist. Similar to Johann Kuhnau, he released several popular musical compositions alongside novels. Under Erdmann II of Promnitz he again took over the management of the court orchestra, until succeeded by the young Georg Philipp Telemann in 1704. His musical oeuvre has largely disappeared, but his historical description still offers useful information on contemporary composers.
Gianpietro Del Buono
About Gian Pietro Del Buono's life has so far hardly been hints, either about his life data, nor about his effects. He was known for his collection of vocal and instrumental works, published in Palermo in 1641, "Canoni, obligi et sonata in varie maniere sopra l'Ave maris stella ... a 3, 4, 6, 7, 8 and 9 voci e le sonata a 4 ". The collection contains 84 canons and 14 sonatas for key instruments, on the theme contained in the title. The composer of the collection was the Genoese noble Giovanni Ambrosio Scriabini, who lived in Sicily. In the preface, Del Buono explicitly refers to the model of his work, which is based on Francesco Sorianos Canoni e obligati di cento e di sorte, sopra l'Ave maris stella (Rome, 1610).
For the 14 sonatas, the term "sonata" emerges for the first time in a solo piece for keyboard instruments. For this reason, the musicologist Willi Apel, in his book History of Organ and Piano Music, was one of the most important representatives of the southern Italian piano school of the seventeenth century until 1700, although these pieces have little in common with the almost simultaneously developing solosonates.
A handwritten copy of the collection is preserved in the "Civico Museo bibliografico musicale" in Bologna, which may indicate an activity of Del Buonos in this city.
1642
With the onset of the English Civil War, musical life in London is restricted as the Puritans close the theatres and outlaw acting. King Charles flees London and sets up court in Oxford.
German composer and theorist Johann Andreas Herbst publishes Musica practice, the first independent singing tutorial with practical exercises.

Monteverdi begins work on L’incoronazione di Poppea (The Coronation of Poppea) in collaboration with the librettist Giovanni Busenello. Based on the licentious life of Nero, the opera sets new standards for characterisation and breaks fresh ground with its focus on non religious historical subject matter.
L'incoronazione di Poppea is an Italian opera by Claudio Monteverdi, with a libretto by Giovanni Francesco Busenello, first performed at the Teatro Santi Giovanni e Paolo in Venice during the 1643 carnival season. One of the first operas to use historical events and people, it describes how Poppaea, mistress of the Roman emperor Nero, is able to achieve her ambition and be crowned empress.

Marco Antonio Pasqualini (25 April 1614 – 2 July 1691) was an Italian castrato opera singer who performed during the Baroque period. He has been described as "the leading male soprano of his day". Pasqualini joined the choir of the Sistine Chapel in 1630. He was also a composer, having written more than 250 arias and cantatas.
Despite being historically addressed as a soprano, Pasqualini's vocal range extended no higher than B5. Thus, he was a mezzo-soprano by modern classification.

6 December
Johann Christoph Bach, German composer and organist, born.
Johann Christoph Bach
Johann Christoph Bach (6 December 1642 – 31 March 1703) was a German composer and organist of the Baroque period. He was born at Arnstadt, the son of Heinrich Bach, Johann Sebastian Bach's great uncle, hence he was Johann Sebastian's first cousin once removed. He was also the uncle of Maria Barbara Bach, J.S. Bach's first wife. He is not to be confused with Johann Sebastian Bach's son, Johann Christoph Friedrich Bach.
Johann Christoph had a reputation as a composer that was only equalled by that of Johann Sebastian within the Bach family during his lifetime. He was organist at Eisenach and later a member of the court chamber orchestra there.

His brother, Johann Michael Bach (Johann Sebastian Bach's father-in-law and Maria Barbara's father), was also a composer. Some of the works were later attributed to Johann Sebastian, but were recently recognized as written by Johann Christoph. One of the most famous works is the cantata Meine Freundin, du bist schön, based on the Song of Solomon. His eldest son, Johann Nicolaus Bach, was also a composer.
Despite his success as a musician, Johann Christoph experienced financial difficulties, which may have resulted in his not having been selected as the guardian of Johann Sebastian when the latter's parents died. Johann Christoph was heavily in debt when he died at Eisenach.
Sebastian Bach described him in his Genealogy (1735) as "the profound composer", thus hinting at his reputation, not just within the family, but within society.

Claudio Monteverdi, the most famous and revered composer in Europe, dies in Venice, aged 76. He is buried in the Church of the Frari, Venice.

Johann Adam Reincken
Johann Adam Reincken (also Jan Adams, Jean Adam, Reinken, Reinkinck, Reincke, Reinicke, Reinike; baptized 10 December 1643 – 24 November 1722) was a Dutch/German organist and composer. He was one of the most important German composers of the 17th century, a friend of Dieterich Buxtehude and a major influence on Johann Sebastian Bach; however, very few of his works survive to this day.
Reincken received primary music education in Deventer in 1650–54, from Lucas van Lennick, organist of the Grote kerk (Lebuinuskerk). In 1654 he departed for Hamburg to study under Heinrich Scheidemann, a pupil of Sweelinck, organist of St. Katharine's Church (Katharinenkirche). In 1657 he returned to Deventer and became organist of the Bergkerk on 11 March; however, after only a year he left for Hamburg again, this time to become Scheidemann's assistant. When the older composer died in 1663, Reincken succeeded him at St. Katharine's. In 1665 he married one of Scheidemann's daughters, and their only child Margaretha-Maria was born three years later.

The composer kept his position at St. Katharine's until his death in 1722, although in 1705 some of the church elders attempted to appoint Johann Mattheson as Reincken's successor. Unlike many other contemporary organists, Reincken died wealthy.
In his lifetime he was heralded as one of the best organists in Germany; he knew Dieterich Buxtehude closely and influenced Vincent Lübeck and Johann Sebastian Bach.

As the English Civil War continues, the Puritan parliamentarians step up their nationwide campaign to purge all churches of organs, stained glass windows and ‘superstitious’ images.

The Book of Common Prayer is abolished and replaced with the Directory for the Puhlique Worship of God, advocating only the unaccompanied singing of metrical psalms.
Sigmund Theophil Staden, aged 36, composes the pastoral Singspiel Das geistliche Waldgedicht oder Freudenspiel genant Seelewig (The Sacred Forest Poem or Play of Rejoicing called Seelewig), a Christian morality play scored for soprano, bass, a supporting cast of six and a small ensemble of strings and winds. Performed this year at court in Nuremburg, Seelewig explores the conflicts between body and soul. It is the earliest surviving German opera.

Instrument maker Antonio Stradivari is born around this time in Cremona.
Singer and composer Barbara Strozzi - adopted (perhaps natural) daughter of the librettist Giulio Strozzi - publishes her first opus, Il primo libhro de madrigali. Her first of eight volumes of vocal music contains madrigals for two to five voices on texts by her father. The music is deeply expressive and frequently virtuosic.
Giulio Strozzi (1583 - 31 March 1652) was a Venetian poet and libretto writer. His libretti were put to music by composers like Claudio Monteverdi, Francesco Cavalli, Francesco Manelli, and Francesco Sacrati. He sometimes used the pseudonym Luigi Zorzisto

Antonio Stradivari
Antonio Stradivari, Latin Stradivarius, (born 1644?, Cremona, Duchy of Milan—died Dec. 18, 1737, Cremona), Italian violin maker who brought the craft of violin-making to its highest pitch of perfection.
Stradivari was still a pupil of Nicolò Amati in 1666 when he began to place his own label on violins of his making. These at first followed the smaller of Amati’s models, solidly constructed, with a thick yellow varnish. In 1684 Stradivari began to produce larger models, using a deeper-coloured varnish and experimenting with minute details in the form of the instrument. His “long” models, dating from 1690, represent a complete innovation in the proportions of the instrument; from 1700, after returning for a few years to an earlier style, he again broadened and otherwise improved his model.

He also made some fine cellos and violas. The Stradivari method of violin making created a standard for subsequent times; he devised the modern form of the violin bridge and set the proportions of the modern violin, with its shallower body that yields a more powerful and penetrating tone than earlier violins. It was long thought that the secret of Stradivari’s acoustically perfect violins lay in their varnish, the formula of which, though much debated, has never been discovered. However, modern research has isolated certain factors that influence the beauty of a violin’s tone. Among these are the thickness (and, hence, the vibrational properties) of its wooden top and back plates, the condition of the microscopic pores within the wood of the violin, and lastly the formula of the varnish. Stradivari’s success probably came from expertly optimizing all these and other factors within his designs.
Stradivari’s sons Francesco (1671–1743) and Omobono (1679–1742) were also violin makers. They are believed to have assisted their father, probably with Carlo Bergonzi, who appears to have succeeded to the possession of Antonio’s stock-in-trade.
Heinrich Ignaz Franz von Biber
(b. Wartenberg, Bohemia, August 12, 1644; d. Salzburg, May 3, 1704)
Austrian violin virtuoso and composer, considered the most capable violinist of his age. His remarkable integration of 17th-century improvisatory practices into fantastical works for solo violin placed him among the elite of his era’s performer-composers. His first major post was in Graz, followed in 1668 with an appointment as musician to the Bishop of Olmutz at Kromerlz in Moravia. In 1670 he left without giving notice and entered the service of the Prince-Archbishop of Salzburg, Maximilian Gandolph von Khuenburg, where his exceptional talents as a performer and composer won him fame and status. He was named deputy Kapellmeister in 1679, and by 1684 he had become Kapellmeister and dean of the choir school at the Salzburg Cathedral. During his years in Salzburg he composed a handful of operas and cantatas, as well as a significant body of sacred works including vespers settings, several masses, and two Requiems. He twice petitioned Emperor Leopold I to be elevated to the nobility (1681,1690), meeting with success on his second attempt and acquiring the right to style himself Heinrich Biber “von Bibern.”
Biber was a careerist and social climber of the first order. Fortunately, he showed the same dedication in his art that he brought to his personal and professional advancement. His most important achievement by far was his set of Mystery or Rosary Sonatas (named for the 15 Mysteries of the Rosary, or Rosenkranzen), written for violin and bass and completed ca. 1676. These works embody the most extensive use of SCORDATURA (an alternate tuning of a string instrument) in the repertoire: 14 of the 15 call for unconventional tunings, all different, creating a seemingly endless kaleidoscope of moods and colors. To cap this monumental cycle of meditations on the events of the life of the Virgin Mary, Biber composed a masterful unaccompanied passacaglia that foreshadows Bach’s unaccompanied string works, written some 50 years later.

Francesco Sacrati’s opera La finta pazza (first performed at Venice, 1641) is presented in the hall of Le Petit Bourbon, Paris. Instigated largely by Cardinal Mazarin, the occasion appears to mark the first staging of an Italian opera in Paris.

A scene from Francesco Sacrati’s opera La finta pazza (The Pretended Madwoman). The French production owed much of its success to the impressive sets and machinery of Giacomo Torelli.
Johann Ambrosius Bach
Johann Ambrosius Bach (22 February 1645 – 2 March 1695 [O.S. 20 February]) was a German musician, father to Johann Sebastian Bach.
The son of Christoph Bach (1613–1661), Ambrosius was born in Erfurt, Germany, as the twin brother of Johann Christoph Bach (1645–1693). Ambrosius was employed as a violinist in Erfurt.

In 1671, he moved his family to Eisenach, in present-day Thuringia, where he was employed as a court trumpeter and director of the town musicians. He married his first wife Maria Elisabeth Lämmerhirt on 1 April 1668, and had eight children by her, four of whom became musicians, including Johann Sebastian. She was buried on 3 May 1694. On 27 November 1694 he married Barbara Margaretha, née Keul (she had already been twice widowed). He died in Eisenach less than three months later. After Johann Ambrosius Bach's death, his two children, Johann Jacob Bach and Johann Sebastian Bach, moved in with his eldest son, Johann Christoph Bach.
Johann Christoph Bach
Johann Christoph Bach (Erfurt, 22 February 1645 – 7 September [O.S. 28 August] 1693, Arnstadt) was a German musician of the Baroque period.
A court and town musician in Arnstadt, he was the third son of Christoph Bach and the twin brother of Johann Ambrosius Bach. He was the uncle of Johann Sebastian Bach.
Andreas Werckmeister
Andreas Werckmeister (November 30, 1645 – October 26, 1706) was a German organist, music theorist, and composer of the Baroque era.Born in Benneckenstein, Werckmeister attended schools in Nordhausen and Quedlinburg. He received his musical training from his uncles Heinrich Christian Werckmeister and Heinrich Victor Werckmeister. In 1664 he became an organist in Hasselfelde; ten years later in Elbingerode; and in 1696 of the Martinskirche in Halberstadt.Of his compositions only a booklet remains: pieces for violin with basso continuo, with the title Musikalische Privatlust (1689).Werckmeister is best known today as a theorist, in particular through his writings Musicae mathematicae hodegus curiosus... (1687) and Musikalische Temperatur (1691), in which he described a system of what we would now refer to as well temperament (named after Bach's opus, "The Well-Tempered Clavier") now known as Werckmeister temperament.
Werckmeister's writings were well known to Johann Sebastian Bach, in particular his writings on counterpoint. Werckmeister believed that well-crafted counterpoint, in particular invertible counterpoint, was tied to the orderly movements of the planets, reminiscent of Kepler's view in Harmonice Mundi. According to George Buelow, "No other writer of the period regarded music so unequivocally as the end result of God’s work," a view harmonious with that of Bach. Yet in spite of his focus on counterpoint, Werckmeister's work emphasized underlying harmonic principles.
