「Threads with palming control of youngest, smallest, most tender」describes the very first foot bindings of a young female in dynastic China before too many of her tarsal bones were no-longer-integrated, the beginning of bending the ARCH of the foot, so the heel and ball by the toes did not make contact yet: GEOMETRIC CHORD SHAPE of a segment connecting two ends of a partial circle arc, defined as a line segment joining two points on any curve, such as a BOWSTRING, the first or last quarter phases of the Moon (「black」and「a great distance」).
　HYPOTENUSE, the longest side of a right triangle, the side opposite the right angle, is derived from the shape bandages binding the「black」and gangrenous, no-longer-integrated feet of a concubine with「long, sticky fibers」:
　「To enable the size of the feet to be reduced, the toes on each foot were curled under, then pressed with great force downwards and squeezed into the sole of the foot until the toes broke. The broken toes were held tightly against the sole of the foot while the foot was then drawn down straight with the leg and the arch forcibly broken. The bandages were repeatedly wound in a figure-eight movement, starting at the inside of the foot at the instep, then carried over the toes, under the foot, and around the heel, the freshly broken toes being pressed tightly into the sole of the foot. At each pass around the foot, the binding cloth was tightened, pulling the ball of the foot and the heel together, causing the broken foot to fold at the arch, and pressing the toes underneath.」

　The use of CHORD as a musical term derives from this geometric shape formed by stringed instruments.「Striking a chord」referred to whacking a concubine's foot to make a point understood, not making music per se, although she may have hollered out a note or two as a 'singing girl.'
　Long「threads」or strings of a musical instrument, played by an「expert, professional」so adeptly that it seems almost「mysterious and bewitching (occult-like).」The right element indicates「very long strings」used with a stringed instrument. Note that in China, the「singing girls」who also「played on your musical instruments」were euphemisms for prostitutes, perhaps because they could use their tongue so well and cause clientele to sing a single sustained musical note very loudly or simply holler out loud, much like a wolf or dog howling.
　Euphemisms such as BRAIDED, twisted CORD, MULTI-COLORED STRANDS or ROPE describe various colors of penile emissions when infected consisting of whitish semen, clear bulbourethral fluid, greenish and/or yellowish pus and gleet, red, brown, and/or black blood, and so on, often with chunky bits.
　STRINGS ON A MUSICAL INSTRUMENT: may refer to the long cloths used to bind feet, or, to「ejaculations in very, very long lengths played by an expert, professional, shaman's business」with these same abilities. A DIVA is a highly distinguished female singer, and the word originates from「divine, a goddess, a really good singing girl」who was trained as the apprentice of a divining female, the local shaman witch doctor. Shamans sold the services of these girls, and sold the girls themselves, too…called 'witch doctors' because they also sold divination services along with sex, and attempted to doctor you up after you contracted a sexually transmitted infectious disease in the 'temple of love.'
