Session 3


 

Chord Sequences. Referring again to Session 1, it is possible to play four of the modal scales (Ionian, Phrygian, Mixolydian, Locrian ) simultaneously in the following chord sequence. Click on the manuscript to listen to the sequence.

The Roman Numerals denote the 'degree' of the scale and therefore the type of chord used. This chord sequence is often used by pianists (or fragments of the sequence) with the following voicing.

This sequence should be practised in this voicing in all twelve keys. In the key of F a Bb must be included. In the key of Bb, a Bb and Eb must be included and so on. Click on the manuscript to listen to the sequence

This voicing is sometimes called 'The Axis of the third'. This is because the third of the scale is the top note of the chord. The 'Axis of the seventh' is also effective in Jazz.

Here are the scale-tone chords of F in axis-7 voicing

This can also be practised in all twelve keys.


In the following example of the first four bars of 'Don't Get Aound Much Any More' by Duke Ellington we have examples of chord voicing. The second bar uses 'axis of the third' voicing and the fourth bar uses a sequence of thirteenths.
