chord progressions in tonal music


These animated demos have been redeveloped to make them available on all platforms. You should be able to run them on desktop computers, laptops, tablets and mobile phones. You will also find that if you use Ctrl +, Ctrl - (⌘ +/- on mac) you will be able to change the size of the demos on descktop computers. Please contact me if you find any issues with the new demos.

These animated demonstrations show the way chord progression patterns in tonal music produce structures similar to sentence structures in natural language.

To get the most from these demonstrations move the pointer over each lowest level syntactic element on the parsing diagram in turn. For example: Static Harmony ..... Dynamic Harmony ..... Chord V ..... Chord I. The descriptions for each element are different on each demonstration and should be read carefully.

Don't move the pointer whilst the demo is playing. If you do this, then press the reload button to recover or wait until the music stops completely.

I hope you find these useful and that they encourage you to learn more about Syntactic Structures in Music.


1) A simple syntactic structure, Haydn: Sonata in D major, Hob XVI:37, III

2) A longer syntactic structure, Mozart: Sonata in A minor, KV 310 (300d)

3) A phrase with a dynamic introduction: Chopin: Prelude Op. 28, No 7.

4) A phrase with a Dominant Prolongation: Bach: Well Tempered Clavier, Book II, Prelude XII

5) A phrase with a Static Coda: to follow if I can find and example short enough to fit on a screen.
