This is a list of events occurring in the 1730s, ordered by year.

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)

Jan Dismas Zelenka (16 October 1679 – 23 December 1745), baptised Jan Lukáš Zelenka and previously also known as Johann Dismas Zelenka, was the most important Czech Baroque composer, whose music was notably daring with outstanding harmonic invention and mastery of counterpoint.

Zelenka was born in Louňovice pod Blaníkem, a small market town southeast of Prague, in Bohemia as the eldest of the eight children born of Marie Magdalena (née Hájek) and Jiří Zelenka. The name Jan Dismas probably originates from his confirmation. His father was a schoolmaster and organist there; nothing more is known with certainty about Zelenka's early years. He received musical training at the Jesuit college Clementinum in Prague. Zelenka played the violone, the largest and lowest member of the viol family, analogous to the double bass in the violin family of stringed instruments. During his studies in Prague, Zelenka wrote his first compositions, all of them oratorial in character.

It is known that Zelenka had served Baron Hartig, the imperial governor who resided in Prague, before becoming a violone player in the royal orchestra at Dresden in about 1710. His emigration from Bohemia was most likely sudden, the reasons for it are not known and became the subject of some speculation. In some monographs, various personal reasons are alleged to be behind his escape, but the truth remains draped in mystery. His first opus in Dresden was "Missa Sanctae Caeciliae" (c.1711).

Yehudi Menuhin, Baron Menuhin, OM, KBE (22 April 1916 – 12 March 1999) was an American violinist and conductor who spent most of his performing career in the United Kingdom. He was born to Russian Jewish parents in the United States, but became a citizen of Switzerland in 1970, and of the United Kingdom in 1985. He is often considered to be one of the greatest violinists of the 20th century.

Yehudi Menuhin was born in New York City, United States, to Bielorussian Jewish parents from what is now Belarus. His sisters were the concert pianist and human rights worker Hephzibah Menuhin and the pianist, painter, and poet Yaltah Menuhin. Through his father Moshe Menuhin, a former rabbinical student and anti-Zionist writer, Menuhin was descended from a distinguished rabbinical dynasty.

Menuhin began violin instruction at age four under violinist Sigmund Anker; his parents had wanted Louis Persinger to be his teacher, but Persinger refused. Menuhin displayed extraordinary talents at an early age. His first solo violin performance was at the age of seven with the San Francisco Symphony in 1923. Persinger then agreed to take Menuhin as a student. When the Menuhins went to Paris, Persinger suggested Yehudi go to his own teacher, Eugène Ysaÿe. He did have one lesson with Ysaÿe, but did not like his method or the fact that he was very old. Instead, he went to the Romanian composer and violinist George Enescu, after which he made several recordings with his sister Hephzibah. He was also a student of Adolf Busch. In 1929 he played in Berlin, under Bruno Walter's baton, three concerti by Bach, Brahms and Beethoven. In 1932 he recorded Edward Elgar's Violin Concerto in B minor for HMV in London, with the composer himself conducting, and between 1934 and 1936 he made the first integral recording of Johann Sebastian Bach's Sonatas and Partitas for Solo Violin.
