If the glove don't fit, I will acquit...
but I really do see aspects of the Golden Mean in my reeds in the following way for the American style reeds I make:
(I like Fibonacci as a tangent approach to undertanding the golden mean and because it frequently occurs in nature, similar to the way the overtone series does.)
My tip and lay I see as one unit, and it measures aprox. 4.5 mm.
My heart measures on the long side of aprox. 7.25 mm.
My back scrape below the heart ( channels or whatever one chooses to call them) measures aprox. 11.75 mm, again on the long side of things.
So the golden mean constant = aprox. 1.618...
Tip of 4.5 * 1.618 = 7.28 which is about how my reed's heart is cut.
Heart of 7.28 * 1.618 = 11.78 which is how long my channels extend below the heart.
The Fibonacci series adds its two previous numbers to generate the next in sequence, so 4.5 + 7.28 = 11.78. So the series or at least a portion of it appears to relate to my reeds dimensions at least for the scraped portion.
I don't consider staple length, because it is essentially an extension of the oboe's bore.
I don't fuss with these measurments while meaking a reed, although I might pay a bit more attention here out.
The 4.5 tip - lay measure is aproximate and from measuring several of my best reeds, they range from 3.5 to 4.5, and the other associated areas also seem to co-vary keeping the sequence intact.
I have not measured these before this thread and waited for the discussion to ensue for a while to see if any other insghts might happen.
Anyone know where the series of 4.5 - 7.28 -11.78, or ratios between those in series would fall in the overtone series?
(Reed crows an equal tempered c'' above an A = 440 hz standard, oboe fundamental is ...? A 220, I think, although someone left the low A off my oboe, but then someone also left the finger tips off my mountain biking gloves, therefore they are aprox. gloves.)
