Tomaso Giovanni Albinoni (1671 – 1751) was an Italian Baroque composer. His output includes operas, concertos, sonatas for one to six instruments, sinfonias, and solo cantatas. While famous in his day as an opera composer, he is known today for his instrumental music, especially his concertos. He is also remembered today for a work called "Adagio in G minor", attributed to him but said to be written by Remo Giazotto, a 20th century musicologist and composer, who was a cataloger of the works of Albinoni. Born in Venice, Republic of Venice, to Antonio Albinoni, a wealthy paper merchant, he studied violin and singing. Relatively little is known about his life, which is surprising considering his contemporary stature as a composer, and the comparatively well-documented period in which he lived. In 1694 he dedicated his Opus 1 to the fellow-Venetian, Cardinal Pietro Ottoboni (grand-nephew of Pope Alexander VIII). His first opera, Zenobia, regina de Palmireni, was produced in Venice in 1694. Albinoni was possibly employed in 1700 as a violinist to Charles IV, Duke of Mantua, to whom he dedicated his Opus 2 collection of instrumental pieces. In 1701 he wrote his hugely popular suites Opus 3, and dedicated that collection to Ferdinando de'medici, Grand prince of Tuscany.

Most of his operatic works have been lost, largely because they were not published during his lifetime. However, nine collections of instrumental works were published. These were met with considerable success and consequent reprints. He is therefore known more as a composer of instrumental music (99 sonatas, 59 concerti and 9 sinfonie) today. In his lifetime these works were compared favourably with those of Arcangelo Corelli and Antonio Vivaldi. His nine collections published in Italy, Amsterdam and London were either dedicated to or sponsored by an impressive list of southern European nobility. Albinoni wrote at least fifty operas, of which twenty-eight were produced in Venice between 1723 and 1740. Albinoni himself claimed 81 operas (naming his second-to-last opera, in the libretto, as his 80th). In spite of his enormous operatic output, today he is most noted for his instrumental music, especially his oboe concerti (from 12 Concerti a cinque op. 7 and, most famously, 12 Concerti a cinque op. 9). He is the first Italian known to employ the oboe as a solo instrument in concerti (c. 1715, in his op. 7) and publish such works, although earlier concerti featuring solo oboe were probably written by German composers such as Telemann or Händel. In Italy, Alessandro Marcello published his well-known oboe concerto in D minor a little later, in 1717. Albinoni also employed the instrument often in his chamber works and operas.

His instrumental music attracted great attention from Johann Sebastian Bach, who wrote at least two fugues on Albinoni's themes (Fugue in A major on a theme by Tomaso Albinoni, BWV 950, and Fugue in B minor on a theme by Tomaso Albinoni, BWV 951) and frequently used his basses for harmonic exercises for his pupils. Part of Albinoni's work was lost in World War II with the destruction of the Dresden State Library. As a result, little is known of his life and music after the mid-1720s.

The famous Adagio in G minor, the subject of many modern recordings, is thought by some to be a musical hoax composed by Remo Giazotto. However, a discovery by musicologist Muska Mangano, Giazotto's last assistant before his death, has cast some doubt on that belief. Among Giazotto's papers, Mangano discovered a modern but independent manuscript transcription of the figured bass portion, and six fragmentary bars of the first violin, "bearing in the top right-hand corner a stamp stating unequivocally the Dresden provenance of the original from which it was taken". This provides support for Giazotto's account that he did base his composition on an earlier source.
