New Bach composition discovered

One of the last pieces of music written by Johann Sebastian Bach has been published for the first time in a new biography of the composer.

The new work is a motet -a style of choral music - adapted from a composition by Bach's long-dead uncle, also called Johann.

It was discovered in an archive in Kiev in the Ukraine which also contains scores of unpublished and unperformed works by Bach's son, Carl.

Professor Christoph Wolff of Harvard University, thinks the motet may have been written to be sung at the composer's own funeral.

However it is not the great composer's last work.

Even on his deathbed, and despite having suffered a stroke, Bach was dictating improvements to a chorale he had written some years before.

But the new motet is probably the last surviving musical manuscript in Bach's own handwriting - which had become stiff, uneven and unnaturally large due to the blindness which affected his final months.

Professor Wolff, author of a new biography of Bach, found the manuscript in Kiev last summer.

It is part of a huge archive of more than 5,000 18th century musical manuscripts which disappeared from Berlin during the Second World War which also include 20 Passions, more than 30 keyboard concertos and many other works, all previously unknown, by Bach's son Carl.
