As played by Caleb Hudson, the Adagio from the Concerto for Oboe Op. 9 No2, transcribed for Eb Alto Trombone & KB.

12 Concerti a cinque (op. 9) is a collection of concertos by the Italian composer Tomaso Albinoni, published in 1722.

The most famous piece from Albinoni's Opus 9 is the Concerto in D minor for oboe (Opus 9, Number 2). It is known for its slow movement. This concerto is probably the second best-known work of Albinoni after the Adagio in G minor (which was once believed to be a reconstruction based on a fragment by Albinoni). The concertos were dedicated to Maximilian II Emanuel, Elector of Bavaria, and were first published in Amsterdam. It is possible, but not certain, that they were written in the Elector's court during a 1722 visit there by Albinoni during performances of his theatrical compositions. These are perhaps his most recognizable works During his lifetime, the self-styled Venetian dilettante became famous across Europe, chiefly for his operas. He was determined not to let the inheritance of his father’s paper and stationery company get in the way of composing and he soon divested himself of any day-to-day operational duties. This left him free to spend much of the 1720s (when he would have been in his fifties) touring the most fashionable international opera houses, overseeing his works. It meant that he found himself in the front line when it came to experiencing the latest advances in the music of the period. He was one of the first in Italy to write for the oboe – an emerging new instrument. This concerto is a near-perfect example of the species.
