"Air on a G String" is taken from the second movement of Johan Sebastian Bach's orchestral suite No 3 in D major. I have arranged it in A because it feels, sits and sounds right to my ear. The piano accompaniment is no more than intermediate.

With this piano sheet music, you can play Johann Sebastian Bach's "Air on the G String".

It's an accurate piano transcription of the whole piece which is not too hard to play, and sounds fantastic!

"Air on the G String" is one of the most famous classical compositions.
It was written by J. S. Bach (1685-1750) as the second movement of his orchestral Suite No. 3 in D major (BWV 1068).

While the piece was just titled "Air" in Bach's original composition, the German violinist August Wilhelmj wrote a new arrangement of the piece in the 19th century. In this version, the first violin was transposed so that it only had to use the G string (the lowest string on a violin).
Since his arrangement contributed in a major way to the piece's fame and popularity, it became known as "Air on the G String" or "Air on a G String".

In any way, it is certainly one of the most beautiful pieces from the Baroque era, and sounds wonderful when played on a piano, too!
