Just a couple of points. When one uses these triads through 3rd intervals -must they be triads -or can they be inversions under the rules. Also, the root may be, let's say, C - E - G - B, but I guess you could use different bass notes?Also, I guess you could use as many intervals of a third as you wished - and then at any time you could go to the diminished 5th from the last chord whenever you liked?Paul

Paul,

The chords can absolutely be inversions. In fact, most of them probably WOULD end up being inversions to make the progression flow, and avoid that 'blocky' sound I mentioned. (Sorry, couldn't think of a better word for it.)

Different bass notes? Yep. And you can use the diminished fifth movement anywhere in the progression it feels right...not only at the end. (I just used that as an example.) Although, in fooling around I find that it does put a dramatic ending on a phrase.

I wrote a piece this week for a documentary about Matisse and Picasso which had this long expository section I was having trouble finding an idea for. I ending up writing this little harp obligatto with two notes moving in contrary motion, the bottom part playing 8th notes moving from root to 2nd of the chord, the top part moving 5th to 3rd. So the bottom part on Cmaj is C-D-C-D, etc. Top part is G-E-G-E, etc. Then I took this through a long series of mediant chord changes, added a pizzicato bass part, then tossed in the occasional woodwind line when there wasn't narration. It was very simple. I finished the scene in no time...and it just worked. The producer was trilled...commenting on how concerned he was that the scene had dragged a little, and how lively the music made it. Now THAT's a practical application!

I had been exposed to the mediant concept before, but the way Scott explained it, it just clicked. Or like I told him...'exploded' would be more accurate.

Can you tell I'm having fun with this?

I have worked these theories to no end, some point at which it became innate to write in suspension, and that is why I have been preaching that PolyTonality is the next step in film music. Not Atonality, but strong firm Polytonaly. Myself, I am an advocate of Bitonality and Binary forms and structures in film music as I believe it to be the purist form of emotional tug and pull. You can hear an example of over an hour of this kind of music in my best score, Hunting Humans, at:

In that score there are passages of 3 to 5 minutes without resolution, but with complete form and power.

Hey PaulR,

There's a great book called "20th Century Harmony" by Vincent Persichetti, that you might enjoy checking out. It's basically just an overview of a whole bunch of different approaches to harmony that appeared during the past century. Polytonality is covered in there, along with many other techniques. It doesn't go into great detail, but it presents a lot of material in a very concise way, and is a brilliant way to set your harmonic imagination in motion.

Unfortunately, I gave my copy away to a musician who did me a big favor. It was a good gift, but I really miss that book sometimes!

Quavers, yup...

I tend to feel the same way about textbooks. But because this one doesn't dwell too long on each idea, or go into extreme detail, it tends to read more like a reference. It's just enough to wet the apetite for exploration, without getting you bogged down in lenthy explanations. I (used to) just open it up at a random page, check out what it had to say, then start messing around on the piano, listening to how the ideas sounded, and experimenting with the structures they provided.

Talking about again, I think I'll try to find another copy myself!

cheers,

J.

Wonderful discussion!!!!

Many thanks.

Fred,
would it be fair to ask you to say something about that intriguing "Mediant Scale" of Scott's you mentioned? Given that, once this journey in 3rds steps begins, we've soon said a swift goodbye to any "Tonic" note?

I've been working on it but so far I'm stumped by all the possible combinations when changing chords.

Yes, quite inspiring - I like Evan's term "writing in suspension", cause that's what it's really all about. The human condition, bittersweet......

back to triads! I love it!

Did I say that? Yeah I like that too.
