The Polyphony Epiphany

Listeners are encouraged to think of Hoagy Carmichael’s “Georgia.” This iconic American song, familiar to everyone, contains some of the most common chordal movements, in particular 1–6 or 5–1. These popular chordal movements appear in almost every popular American song and indeed in most classical music. What the performer wants (master or beginner), is a colorful way to perform the commonplace. 

The CDs, like the online samples, were recorded as if played as a performance, with little or no silence between the individual modulations. We hope the listener will enjoy the effect. 

The Polyphony Epiphany began not as a grand vision for a major work but as solace for a troubled artist. In a time when life seemed to be going against him, Art turned to the keyboard for strength. 
He started simply by writing down the standard jazz transitions he knew by heart. These are probably familiar to most jazz enthusiasts, aka “jazz clichés.” Over time, as the work progressed, a transformation took place, for the artist as well as the work. As he began to exhaust the familiar clichés, he was already considering the idea of infinite possibilities, and he widened his scope. The first 250 or so have many similarities and may give the impression that the whole work is not as widely varied as it actually is. The listener is encouraged to persist and experience the transformation as it unfolded for the composer. 

The last entry in The Polyphony Epiphany is # 1107. The composer chose to stop writing after # 1107 in part because the number itself does not suggest finality; his ultimate intention was to instill in the listener an idea of virtually infinite possibilities, and that the study of all these variations should serve more as an introduction than a summation. 

Still, # 1107 does serve as a conclusion for the work, and the composer even gave it a name: “Done in Thirty-one”, as it ends with the 31 chords. The first section of the track experiments with some of the 31 chords, with each chord named over its conventional notation. The second half is the complete “Done in Thirty-one”. An explanation follows: 

There are 4 natural triads that result from the major and minor scales: major, minor, diminished and augmented. 

• Major — because there are 12 different notes, there are 12 major chords 
• Minor — because there are 12 different notes there are 12 minor chords 
That makes 24 
• Diminished – the diminished chord is symmetrical, made up of 4 notes, all minor thirds, Therefore there are only three different diminished chords 
That makes 27 
• Augmented – an augmented chord is made up of major thirds, also symmetrical, therefore there are 4 different augmented chords. 
That makes 31 
Any of these chords, superimposed over the dominant 7th in a 
5–1 progression, can produce instant extensions or alterations sounding like anyone from Bach to Bill Evans (and beyond!). 
Important notes: 

Some of the modulations go beyond C to A minor: The whole book is basically just working with the first three chords of Georgia; C, E7, A minor, a progression that occurs in countless songs. Most of what you hear is a variation on the one measure of the E7 chord that segues to A minor. There are however, a number of variations in The Polyphony Epiphany that extend the progression a measure or two beyond A minor. In these cases, notation is provided for the C-to-A-minor part. Enjoy the rest for the context.
