A cantata (literally "sung", derived from the Italian word "cantare") is a vocal composition with an instrumental accompaniment, typically in several movements, often involving a choir.

The meaning of the term changed over time, from the simple single voice madrigal of the early 17th century, to the multi-voice "cantata da camera" and the "cantata da chiesa" of the later part of that century, from the more substantial dramatic forms of the 18th century (including the 200-odd church and secular cantatas of Johann Sebastian Bach) to the usually sacred-texted 19th-century cantata, which was effectively a type of short oratorio. Several cantatas were written for special occasions, such as Christmas cantatas.

The term originated in the early 17th century simultaneously with opera and oratorio. Prior to that all "cultured" music was vocal. With the rise of instrumental music the term appeared, while the instrumental art became sufficiently developed to be embodied in sonatas. From the beginning of the 17th century until late in the 18th, the cantata for one or two solo voices with accompaniment of basso continuo (and perhaps a few solo instruments) was a principal form of Italian vocal chamber music.

Johann Pachelbel ( /ˈjoʊhɑːn ˈpækəlbɛl/ or /ˈpɑːkəlbɛl/;German: [ˈjoːhan ˈpaxɛlbəl], baptised September 1, 1653 – buried March 9, 1706) was a German Baroque composer, organist and teacher, who brought the south German organ tradition to its peak. He composed a large body of sacred and secular music, and his contributions to the development of the chorale prelude and fugue have earned him a place among the most important composers of the middle Baroque era.

Pachelbel's music enjoyed enormous popularity during his lifetime; he had many pupils and his music became a model for the composers of south and central Germany. Today, Pachelbel is best known for the Canon in D, the only canon he wrote – although a true canon at the unison in three parts, it is often regarded more as a passacaglia, and it is in this mode that it has been arranged and transcribed for many different media. In addition to the canon, his most well-known works include the Chaconne in F minor, the Toccata in E minor for organ, and the Hexachordum Apollinis, a set of keyboard variations.

Alexander Nevsky (Russian:  Алекса́ндр Яросла́вич Не́вский​ (help·info), Aleksandr Yaroslavich Nevskiy; pronounced [ɐlʲɪˈksandr jɪrɐˈslavʲɪtɕ ˈnʲefskʲɪj]; 30 May 1220 – 14 November 1263, proclaimed Saint of the Russian Orthodox Church by Metropolite Macarius in 1547) was the Prince of Novgorod and Grand Prince of Vladimir during some of the most trying times in the city's history. Commonly regarded as the key figure of medieval Rus, Alexander was the grandson of Vsevolod the Big Nest and rose to legendary status on account of his military victories over the German and Swedish invaders while employing collaborationist policies towards the powerful Golden Horde.

From Tales of the Life and Courage of the Pious and Great Prince Alexander found in the Second Pskovian Chronicle, circa 1260–1280, comes one of the first known references to the Great Prince:

"By the will of God, prince Alexander was born from the charitable, people-loving, and meek the Great Prince Yaroslav, and his mother was Theodosia. As it was told by the prophet Isaiah: 'Thus sayeth the Lord: I appoint the princes because they are sacred and I direct them.' "... He was taller than others and his voice reached the people as a trumpet, and his face was like the face of Joseph, whom the Egyptian Pharaoh placed as next to the king after him of Egypt. His power was a part of the power of Samson and God gave him the wisdom of Solomon ... this Prince Alexander: he used to defeat but was never defeated ..."

Peter Schreier (born 29 July 1935) is a German tenor and conductor.

Schreier was born in Meissen, Saxony, and spent his first years in the small village of Gauernitz, near Meissen, where his father was a teacher, cantor and organist. In June 1945, when Schreier was almost ten years old, and just a few months after the destruction of Dresden, he entered the boarding school of the famous Dresden boys' choir, the Dresdner Kreuzchor (Choir of the Kreuzkirche or Church of the Cross). The choir had just been re-established. The young Peter and the few other choir members and teachers lived in a cellar in the outskirts of Dresden.

The conductor of the Kreuzchor, Rudolf Mauersberger, soon recognized Peter Schreier's great talent. He let him sing many solo alto parts and also created compositions that perfectly fitted Peter's boy voice. Solo recordings of Peter Schreier were made at the time (1948-1951) and are obtainable on compact disc even today.

Schreier was 16 years old when his voice broke, and he became a tenor, as he had passionately wished, because of the several Evangelists - all tenors - in J.S. Bach's Passions and in his Christmas Oratorio. After he had decided to become a professional singer he took lessons, at first privately, then later on at the Dresden Academy of Music. He had enough time to also study choral and orchestral conducting.
