The traditionally shaped sound-holes in instruments such as violins and cellos are referred to by what letter of the alphabet?
Sound board (music) only in timbre. The string would produce the same amount of energy without the board present, but the greater surface area of the sound board moves a greater volume of air, which produces a louder sound. Sound boards are traditionally made of wood (see tonewood), though other materials are used, such as skin or plastic on instruments in the banjo family. Wooden sound boards typically have one or more sound holes of various shapes. Round, oval, or F-holes appear on many plucked instruments, such as guitars and mandolins. F-holes are usual in violin family instruments. Lutes commonly have elaborate rosettes.
History of the alphabet that are not used as national scripts today, a few are clearly independent in their letter forms. The Zhuyin phonetic alphabet derives from Chinese characters. The Santali alphabet of eastern India appears to be based on traditional symbols such as "danger" and "meeting place", as well as pictographs invented by its creator. (The names of the Santali letters are related to the sound they represent through the acrophonic principle, as in the original alphabet, but it is the "final" consonant or vowel of the name that the letter represents: "le" "swelling" represents "e", while "en" "thresh grain" represents "n".)
