J. S. Bach (1685-1750) was a German Baroque composer who is revered for the originality and skill of his contrapuntal and harmonic techniques. Although he spent most of his life working as an organist and choirmaster, he was familiar with many different keyboard instruments. He utilised this knowledge when composing his two volumes of The Well-Tempered Clavier (1722 and 1742), each a collection of 24 Preludes and Fugues in which he explored the different harmonies of every key.
Prelude And Fugue In A Major BMV 889 is No. 20 from Book Two of the Clavier. It is written in a typical Baroque form. This popular edition from the highly-regarded musicologist Orlando Morgan is designed with the performer in mind, and is still seen as the best edition available for students today.
