Ernő Lendvai (February 6, 1925 – January 31, 1993) was one of the first music theorists to write on the appearance of the golden section and Fibonacci series and how these are implemented in Bartók's music, he also formulated the axis system, acoustic scale and alpha chord, an octatonic scale is any which number note musical scale?
Octatonic scale An octatonic scale is any eight-note musical scale. The scale most often meant by this term is one in which the notes ascend in alternating intervals of a whole step and a half step, creating a symmetric scale. In classical theory, in contradistinction to jazz theory, this scale is commonly simply called the octatonic scale (or octatonic collection), although there are forty-two other non-enharmonically equivalent, non-transpositionally equivalent eight-tone sets possible.
Erdős–Tetali theorem In additive number theory, an area of mathematics, the Erdős–Tetali theorem is an existence theorem concerning economical additive basis of every order. More specifically, it states that for every fixed integer formula_1, there exists a subset of the natural numbers formula_2 satisfyingformula_3where formula_4 denotes the number of ways that a natural number "n" can be expressed as the sum of "h" elements of "B."
