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.
Berklee method In music performance and education, the Berklee method is the music theory, terminology, and practice taught at Berklee College of Music, the largest independent college of contemporary music in the world. The "Berklee method" was founded by Lawrence Berk after study with Joseph Schillinger regarding the latter's, "elaborate system of composition that employed mathematical permutation and combination process to generate rhythms, harmonies, and melodies". Later, attempting to codify jazz and popular music practice, the Berklee method often differs from common practice harmony and voice-leading rules or guidelines.
