Post-Tonal Harmony Ideas (2)

In Post-Tonal Harmony Ideas (1), we examined tonality, atonality, and post-tonality, and explored two possibile ways of using tonal chords in a post-tonal context. 

One way is to superimpose triadic structures in order to create sonorities that would not normally be found in tonal music; perhaps the most famous example of this is Stravinsky's "Petroushka" chord: A combination of F# major and C major chords. Another Stravinsky example comes from the Rite of Spring, in the section called "Augurs of Spring/Dances of the Young Girls," which features a strongly-rhythmic repeated chord and irregular accents; the chord is E major in the lower strings (spelled enharmonically as Fb), and Eb7 in the upper strings.

A second way uses triadic-based, tonal chords in progressions that do not follow the chord-flow practices of tonal harmony (e.g., avoiding descending fifth root movements). 

I will explore the first idea (e.g., Petrushka chord, and other combined sonorites) at greater length in my next post, but  the objective today is to expand on the second idea, using the last musical example from Post-Tonal Harmony Ideas (1) as a starting point.

The example below is a very short composition written specifically for today blog post, beginning with the piano chord progression from the end of my previous post. The first five bars are virtually identical (dynamics and octave doublings have been added), but a trumpet enters at the end of m. 5. The piano chord progression is repeated in the second system while the trumpet plays a new melodic line, and the last two systems are an expansion of this chord progression, while the trumpet continues to play its melody.

For the trumpet notes, I picked pitches that, at the point they begin, are not part of the accompanying piano chord, although several subsequent piano chords include the pitch being held by the trumpet. My rationale for doing this was to increase the sense that this was not intended to be heard as an example of tonal harmony.

Have a listen; discussion to follow:







Dreary, isn't it? ;-)

As a reminder, the objective was to (a) create a succession of tonal chords that do not follow the typical chord progression patterns in tonal harmony, and (b) expand this into a short composition.

You might well ask, why would anyone want do such a thing? Isn't this like putting old wine in new bottles (i.e, repackaging something old and calling it new)?

Why:

This was an experiment. Whether it produced anything useful or not is up for debate, but there would have been no way of knowing if this approach (and yes, it is rather like putting old wine into new bottles) had any useful compositional possibilities to offer had we not tried it. FWIW, I don't know of any music that actually does this, although I would not be surprised to find that others have explored this approach as well.

Exploring new ways of using old harmonic structures completely violates the spirit and practice of modernism, and I therefore suspect many contemporary composers would reject this approach. We live in what some have called a "post-modern" period, however, within which this sort of exploration is completely appropriate.

Whether it is appropriate or not, the main thing most composers would want to know is this: Is there any situation in which this approach could be compositionally useful to me? I suggest that you ask yourself this question while playing the audio clip above at least three times, and, if you haven't run screaming from the room by the end of the third play-through, please share your thoughts in the "comments" section below. It's fine to decide that you do not find it worth exploring, but, whether you find it potentially useful or useless, I'd be interested in your thoughts.

Also, if you would be willing to share a chord progression that you came up with, and that fits this approach (tonal-based sonorities that do not follow the harmonic progressions associated with tonality), please do so in the "comments" section.
