Bach Air on a G String Wikipedia: http://en.wikipedia.org/wiki/Air_on_the_G_String
The original orchestral suite was written by Bach for his patron Prince Leopold of Anhalt some time between the years 1717 and 1723. The title comes from violinist August Wilhelmj's late 19th century arrangement of the piece for violin andpiano. By transposing the key of the piece from its original D major to C major and transposing the melody down an octave, Wilhelm was able to play the piece on only one string of his violin, the G string. Later, a spurious story was put about that the melody was always intended to be played on the G string alone.
Johann Sebastian Bach (Wikipedia) - http://en.wikipedia.org/wiki/Johann_Sebastian_Bach
Johann Sebastian Bach (31 March [O.S. 21 March] 1685 -- 28 July 1750) was a German composer and musician of the Baroque period. He enriched established German styles through his skill in counterpoint, harmonic and motivic organisation, and the adaptation of rhythms, forms, and textures from abroad, particularly from Italy and France. Bach's compositions include the Brandenburg concertos, the Mass in B minor, The Well-Tempered Clavier, two Passions, keyboard works, and more than 300 cantatas, of which nearly 100 cantatas have been lost to posterity. His music is revered for its intellectual depth, technical command, and artistic beauty.
