The key movement is fast and chords do not always resolve as expected. In particular, we discover how Bach uses a number of unresolved dominant 7ths back to back, making this a radical approach for Baroque times. Discover what Bach is doing and how successfully it works. We also take a look at the choice of harmony, the part writing, dealing with harmonic and melodic minor, 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.
