This easy arrangement for trumpet and Trombone duet was written to be uncomplicated to perform and understand the structure of the piece. It can be freely played by beginning students, because of the ease imposed on the piece; however, this does not prevent it from being played by professionals and music teachers. It is also ideal for academic recitals, student method and ceremonies that are arranged in the same way as the piece contains. The original piece is part of Johann Sebastian Bach's Suite No. 3 for orchestra, in D Major, BWV 1068, written for Prince Leopold of Anhalt. The so-called Air on the G String dates from one of these latter employments. In the service of the Prince of Cöthen, Bach composed not only the famous Brandenburg Concertos, but also several orchestral suites, from the third of which comes the Air on the G String. This curious title derives from a later arrangement of this piece for violin solo, in which the melody is played entirely on the lower, higher string of the instrument.
