In this chapter we mainly concentrate on two “dominant” progressions: (1) progressions down a fourth; and (2) secondary (or applied) dominants. From your music theory, you may have learned about V of V chords (an example of a secondary dominant). Secondary dominants usually introduce chromaticism, and often propel the music forward strongly.
This chapters lists different kinds of keyboard spacings/voicings, as well as progressions descending by step or down a 4th or a 5th. Using the chorus, Give Thanks, practice its progressions that descend by step or descend a 4th or a 5th. Added second chords and drop 2 voicings are also mentioned briefly.
