"Air on the G String" by J.S.Bach, also known as "Air for G String" is the second movement of Johann Sebastian Bach's Orchestral Suite No. 3 in D major, BWV 1068. The arrangement differs from the original in that the part of the first violins is transposed down so that the entire piece can be played on just the violin's lowest string (the G string). In performance, that part is generally played by a single violin (instead of by the first violins as a group). This Play Along contains the Viola Part of the orchestra.
