Structure
A major scale may be seen as two identical tetrachords separated by a whole tone, or whole step, the new set of steps "Whole:Whole:Half:Whole:Whole:Whole:Half"(in Semi-tone 2 2 1 2 2 2 1). Each tetrachord consists of two whole steps followed by a half step. Western scales do not skip any line or space on the staff, and they do not repeat any note with a different accidental. This has the effect of forcing the key signature to feature just sharps or just flats.

Famous quotes containing the word structure:
“A committee is organic rather than mechanical in its nature: it is not a structure but a plant. It takes root and grows, it flowers, wilts, and dies, scattering the seed from which other committees will bloom in their turn.”
—C. Northcote Parkinson (1909–1993)
“The philosopher believes that the value of his philosophy lies in its totality, in its structure: posterity discovers it in the stones with which he built and with which other structures are subsequently built that are frequently better—and so, in the fact that that structure can be demolished and yet still possess value as material.”
—Friedrich Nietzsche (1844–1900)
“I really do inhabit a system in which words are capable of shaking the entire structure of government, where words can prove mightier than ten military divisions.”
—Václav Havel (b. 1936)
