Occasionally you'll find that even Bach doesn't follow the rules of four-part harmony however he often has a good reason to break them. This video takes a look at one of his Chorales in which some rules are broken in order to achieve a better musical effect. Join us as we examine the choice of harmony and modulation, the part writing, the use of accented and unaccented passing notes, plus other features of the Bach Chorale style. Useful for anyone wanting to improve their ability to write harmony, to analyse harmony, or to understand the detail of Bach's style. Join us on this exciting journey to delve inside the mind of the great J. S. Bach.
