Carl Philipp Emanuel Bach (1714 -1788), a German musician
and composer, was the fifth child and second (surviving)
son of Johann Sebastian Bach. C.P.E. Bach's work was of
great significance in the development of the style and
forms of the classical school and both Mozart and Haydn
were indebted to him.
The Sonata in A minor is very popular today and is played
on a variety of instruments including flute, oboe,
clarinet and saxophone. The work was composed during
1747, while Bach was in Berlin. Although Bach's autograph
manuscript has been lost, this sonata was published during
his lifetime. It appeared in an anthology, Musicalisches
Mancherly, and also as a single offprint during 1763.
The current edition is based on a facsimile of that first
publication. Every attempt has been made to follow the
original intent of the composer; however, where the
markings were vague, we have made editorial decisions
for clarity and consistency.
