Year 1734 (MDCCXXXIV) was a common year starting on Friday (link will display the full calendar) of the Gregorian calendar and a common year starting on Tuesday of the 11-day slower Julian calendar.

Riccardo Broschi (ca. 1698–1756) was a composer of baroque music and the brother of the opera singer Carlo Broschi, known as Farinelli.

Broschi was born in Naples, the son of Salvatore Broschi, a composer and chapelmaster of the Cathedral of the Puglinese citizens, and Caterina Berrese (according to the Book of Baptisms of the Church of S. Nicola, today near the Episcopal Archives).

The Broschi family moved to Naples at the end of 1711, and enrolled Riccardo, their firstborn, in the Conservatory of S. Maria di Loreto, where he would study to become a composer under G. Perugino and F. Mancinipresso. Salvatore, meanwhile, died unexpectedly, at age 36, on 4 November 1717. Caterina subsequently made Riccardo head of the family.

He made his debut in 1725 with La Vecchia Sorda. Next, he moved to London in 1726 and stayed there until 1734 and wrote six heroic operas, his most successful being Artaserse. In 1737 he moved to Stuttgart and briefly served at the Stuttgart court (1736-7) for Charles Alexander, Duke of Württemberg, then returned to Naples before joining his brother in Madrid in 1739. He died in Madrid.

Johann Sebastian Bach (31 March [O.S. 21 March] 1685 – 28 July 1750) was a German composer, organist, harpsichordist, violist, and violinist of the Baroque Period. He enriched many established German styles through his skill in counterpoint, harmonic and motivic organisation, and the adaptation of rhythms, forms, and textures from abroad, particularly from Italy and France. Bach wrote much music, which was revered for its intellectual depth, technical command, and artistic beauty. Many of his works are still known today, such as the Brandenburg Concertos, the Mass in B minor, the Well-Tempered Clavier, and his cantatas, chorales, partitas, passions, and organ works.

Bach was born in Eisenach, Saxe-Eisenach into a very musical family; his father, Johann Ambrosius Bach was the director of the town's musicians, and all of his uncles were professional musicians. His father taught him to play violin and harpsichord, and his brother, Johann Christoph Bach taught him the clavichord, and exposed him to much contemporary music. Bach also sang, and he went to the St Michael's School in Lüneburg, because of his skill in voice. After graduating, he held several musical posts across Germany; he served as Kapellmeister (director of music) to Leopold, Prince of Anhalt-Köthen, Cantor of Thomasschule in Leipzig, and Royal Court Composer to August III. Bach's health and vision declined in 1749, and he died on 28 July 1750. Modern historians believe that his death was caused by a combination of stroke and pneumonia.

Sebastian Bach (born April 3, 1968) is a Canadian heavy metal singer who achieved mainstream success as frontman of Skid Row from 1987 to 1996. Since his departure from Skid Row, he has had many television roles, acted in Broadway plays, and led a successful solo career.

Bach was born Sebastian Philip Bierk on April 3, 1968, in Freeport, Bahamas, and raised in Peterborough, Ontario, Canada. He attended nearby Lakefield College School in the same class as Michael Kulas, of the British rock group James, a year behind Felipe, Prince of Asturias and a year ahead of the comedian/actor Will Arnett. He is of Norwegian, French Canadian, and Native American descent. Bach's father was the visual artist David Bierk. He is the brother of retired NHL goaltender Zac Bierk, model/actress Heather Dylan Bierk, and Toronto-based artists Jeff, Nick, Alex, and Charles Bierk.

Skid Row initially formed in the late eighties with lead singer Matt Fallon. They began playing at various New Jersey clubs. Fallon would soon leave the band in 1987, leaving Skid Row without a singer. Bach, who had just left his previous band Madam X, was spotted singing at rock photographer Mark Weiss's wedding and the members asked him to join. He turned them down, but changed his mind after hearing the demo tapes of "Youth Gone Wild" and "18 and Life". He sent them a demo of him singing "Saved By Love." They loved it and flew him to New Jersey where they began playing gigs. Sebastian also recorded demos with Bon Jovi & Sabo's friend Jack Ponti. (The song "She's on Top" later came out on Jack Ponti Presents Vol. 1)

Hieronymus Albrecht Hass (variants Haas, Hasse, Hase, Hasch) (1 December 1689 - 19 June 1752) (dates of baptism and burial) was a German harpsichord and clavichord maker. He was the father of Johann Adolph Hass, who also made harpsichords and clavichords.

He received Hamburg citizenship on 2 October 1711, and was born and died there. In 1713 he was described as Instrumentenmacher and Clavirmacher on his son's birth certificate. The latest known instruments by him are two unfretted clavichords, dated 1744; a Clavicimbel for Duke Friedrich Carl von Plön was delivered the same year.

The first recorded reference to his family was in 1758, when Adlung described 'Hasse in Hamburg' as the maker of a cembal d’amour. Later, in 1773, English music historian Charles Burney noted 'Hasse, father and son, both dead' as German organ builders, and that 'their Flügel and Claviere are much sought after'.

Of their instruments, Frank Hubbard wrote that 'only one has what could be regarded as a normal disposition'. Their surviving harpsichords show an attempt to develop the instrument in a number of ways: one from 1721 is 2.58 m long and one from 1723 has the unusual disposition 8' 8' 8' 4'. Hass occasionally used a 16' set of strings (an octave below standard 8' pitch) and a 2' set (2 octaves higher than 8' pitch) for part of the keyboard.
