Creative harmony with closed eyes #

Practicing chord progressions with basic block chords, with closed eyes proves to be a good exercise. Instead of leaping perfect fifths I step chromatically, and in whole steps, as a simpler form approach to this problem. I already find insight into understanding how shapes of major 7th chords connect, what their is is. Mistakes, an essential part of the learning process (we love mistakes), can be used creativel as musical building blocks. For example, I play C∆, then trying to play A∆, I play some random combination of keys. Now, I will try to notice the sound, shape, and position of this random "mistake", and move back to the C∆, and then try to play the same random chord again. Then repeat this, and perhaps lift my arms away from the keyboard, and let them fall, to the random chord, or the C∆, or their inversion, or their slight alternation.

Learning the basic sevillanas guitar patterns is fun, and very meaningful. I thought only already virtuoso guitar players can benefit from playing flamenco, but I was wrong.

Yes! This task is so cool. I guess this is why mathematics is said to be psychedelic. It is from Harold Jacobs "Mathematics, a Human Endeavor":

In how many ways can a casting director choose a mother, a father, and one child, from two actresses, three actors and four children? Four, three and two parallel lines form triangles, the same number of possible triangles as the question in the task

Have you read "10^14 poems" by Raymond Queneau? I thought it was a massive book, but it's a mere pamphlet. A very cool idea, a book of 14 line sonnets:
