prefatory
adjective
of, relating to, or of the nature of something introductory.
More about prefatory
Prefatory “of or relating to something introductory” is based on the Latin noun praefātiō “a saying beforehand,” plus the adjective-forming suffix -ory. Praefātiō became Medieval Latin prēfātia and then became Middle French preface, which English has borrowed. In this way, prefatory and preface are doublets, two words in a language with the same origin but that took different pathways to get there—in this case, directly from Latin and by way of French, respectively. Latin praefātiō is a compound of prae “before,” which is the source of English pre-, and fārī “to speak,” which is the source of affable, fable, fate, and infant. Prefatory was first recorded in English circa 1670.

Vladimir Nabokov believed that inspiration comes in phases. First, he wrote, there’s the “prefatory glow,” the feeling of “tickly well-being” that banishes all awareness of physical discomfort. The feeling does not yield its secret just yet, but a window has been opened and some wind has blown in.
“My question is more of a comment” is a prefatory refrain one comes to dread hearing. You steel yourself for the digressive, long-winded tirade, incoherent to the point of lunacy.
mbira
noun
a musical instrument of what is now Zimbabwe and Malawi that serves as a resonating box, to which vibrating metal or wooden strips are attached for plucking.
More about mbira
Mbira “a musical instrument made from a gourd” is a borrowing from the Shona language. Though Shona mbira is of unclear origin, some linguists hypothesize connections to ambira, kalimba, and marimba, which are all xylophone-like instruments originating in southern Africa. The Shona language is spoken in what is now Zimbabwe, and it belongs to the huge Bantu group of languages, which is found throughout western southern Africa and also includes Wolof, Xhosa, Yoruba, and Zulu. Mbira was first recorded in English circa 1910.
how is mbira used?
The mbira, or Zimbabwean thumb piano, is a revered ceremonial instrument from Southern Africa with two rows of metal keys mounted on a wooden soundboard. Players use thumb and forefinger to pluck the keys up or down, creating percussive, often haunting tones. Traditional mbira song lyrics are evocative and impassioned, often accompanied by call and response singing and guitar.
Materials such as bottle caps or beads can be attached to the instrument to create its signature buzzing sound. The mbira remains a vital cultural emblem of the community as it is often played in a variety of Shona ceremonies … The music of the mbira the Shona people have been able to pass down over hundreds of years and generations.
heliotropic
adjective
turning or growing toward the light.
More about heliotropic
Heliotropic “turning toward the light” is a compound of the forms helio- “sun” and -tropic “turned toward.” Helio- comes from Ancient Greek hḗlios “sun,” which is also the source of the word helium, named for its presence in the chemical composition of the Sun. Meanwhile, -tropic is based on Ancient Greek tropikós “pertaining to a turn,” from trópos “turn.” This same root word is behind English tropical, which we tend to associate today with hot weather and the naming of storms, but the literal sense of tropical describes the zone in which the Sun travels directly overhead in the sky. Heliotropic was first recorded in English in the early 1870s.

But they have designed [solar panel technology] that they say can be about 30 to 40 percent more effective. They were inspired by the idea that flowers and plants naturally turn to face the sun. They call it, let’s say it’s something called a heliotropic effect, and it’s just because of the direction that the sun strikes and they move.
Most seedling plants are strongly heliotropic, and it is no doubt a great advantage to them in their struggle for life to expose their cotyledons to the light as quickly and as fully as possible, for the sake of obtaining carbon.
