Hi guys, I'd like to share with you something I've been briefly workin'on, that i sometimes use to "freshen up" my ears.
Maybe you've already figured it out, but for the ones who didn't, here it is:
Some months ago I was reading the introduction of the Slominsky Thesaurus, in my third of forth failed attempt to
practice something from that book, and i noticed something that at a first read i didn't.
While explaining the mechanism, the terms and the concepts, often in a mathematical way, the author wrote that there
was the possibility of using two major and two minor triads without repeating a single note, and the same thing was possible
with four triads of different nature, diminished, minor, major and augmented.
Simple math of course, 12 notes...but i didn't know wich triads to use to get the result.
I took a paper and started to figure it out,just for curiosity (and speculation, I suppose).
Here they are:
Two major triads a tone away, and two minor triads a tone away where the first one is a minor 6 away from the first
major triad. For example C,D,Ab- and Bb-.
I think of them as I, II, bVI- and bVII-.
The second possibility, the one with four different triads is, for ex:
C°,G-,Emaj and F+. The order is diminished/minor/major/augmented just for alteration purposes I guess,
the same order named in the book, but for a quick thinking I like to think at them as
I°,IIImaj,IV+ and V-.
I started to play them a little and find them very geometrical in a sense,you can play any inversion you want, and after
the last note move up or down a half-step and you'll find a note to start the next triad, tons of possibilities.
Of course it's mental, of course i wouldn't play this on "But not for me" or "Blue Moon", but it's refreshing for the ears
(of course,being a serial combination of 12 different notes) and challenging to the hands.
It's playable too in some semi-free situations or advanced chromatic languages.
And it's a way to "improvise" dodecaphonic series. Freaky.
I hope this can be helpful or, at least, interesting to you.
Thanks for reading,
sorry for my english ;)
