music theory pattern

(Actually Jack Campin here, my computer is under a dust cover at the moment).



Music theory geeks only. Take a look at this:

It does more than he says, the unlabelled triangles are minor triads and there are all kinds of interesting relationships between them (e.g. a move across a vertical line takes you between a major triad and the triad of its relative minor).



I imagine colouring the triangles in 12 different colours in a wheel according to the circle of fifths, with some added feature to distinguish the major and minor ones. Not sure where you could get a coordinated selection like that, though.



I could sit up in bed and play my quilt on the accordion.



Unfortunately doing four-note chords needs three dimensions.



(We are into wacky themes for quilt designs at the moment, the last one we finished was a kid's quilt with a border representing a road system complete with standard markings like white lines, zebra crossings and yellow parking-restriction lines, in a scale about right to drive toy cars round it).


I don't have the music theory to follow all this but I have often thought a really "accurate" run of hand dyed fabrics would make a wonderful quilt based on a mathematical progression (perhaps Fibonacci?). I designed a quilt based on a Mobius shape but I haven't been able to get the dying done to make it yet.

A progression of 32 from one colour to another in one dye session is way beyond my capabilities, so I will probably try for 16 shades light-to-dark, with a common very light. If it works, Fibonacci may be next lol

Have you though about using the shades and colours achievable in hand dyes to represent your music theory?

Thought of it. Then considered that given my efforts at hand dyeing, the colour spectrum would end up bluey-beige to pinky- beige to beigey-beige with a spotty-beige in the middle.

In fact I have definite synaesthetic associations with the common keys used in Scottish music - A major is green, D major is yellow, C major and E minor are different shades of pale blue, etc. But I don't have colours for all the keys and they don't relate to the circle of fifths.

I am studying Fibonacci amongst other things and have dyed the fabric and assembled my effort at his theory.Good job its folded when in use to form a cover for my work!Its the last entry in my quilts if anyone is interested to look.

Whow Cheryl. That would be so great , its beautiful!! Great design!

Omigosh, Cheryl -- that's gorgeous! I hope you do make it. :)

I haven't been around much in the past couple of days and don't know how much I'll be around today, either. I'm having telephone problems, which affects my DSL hookup, of course. :( Round two starts today.... Meanwhile, I'm trying to catch up a bit, but I suspect I'll have to mark most of the messages as read and start fresh. :S

Oh, I *like* that, Estelle! :)

I've been musing about Fibonacci; like others in this thread; *and* the golden ratio applied to color. I haven't seen any examples, but I'd to see how a series of colors looked if you kept applying the golden ratio (1.618 or .618) to choose the *frequency* of the next color. So if you started with a deep purple and took the next 5 or 6 "phi" colors; would it look good?

And; if you did it by musical notes, pick the color frequencies such that the their ratios matched up to the ratio of the *note* frequencies in the layout with the triads.

Hand dyes.

Bright true colors for major chords; drabber grey overdyed for minor chords? Or a light cheery pastellish shade for major, darker sadder shade for minor? Ah, if you do that, you can then save the bright trues for the circles (applique?).....

Wouldn't work; the frequency range of visible light only covers about an octave. Two golden ratio steps and you'd be into the infrared.

Newton tried some way to compress the ratios and line up light frequencies with sound ones - it's somewhere in the _Opticks_ but I can't remember the details and it wasn't very convincing.
