    • n decad The number ten; in a Pythagorean or cabalistic sense, as an element of the universe, the tetractys or quaternary number. In this sense the form decad is exclusively used. The decad was considered significant as being the base of numeration and potentially embracing all numbers, and thus representing the cosmos or its source. It was further considered as highly significant that the decad is 1 + 2 + 3 + 4, for four naturally suggests organic perfection, since melodies and other compositions are best divided into four parts, and for other reasons; so that the greatness of Pythagoras as a philosopher was summed up in his title of “revealer of the quaternary number.” By cabalists it is considered important as being the number of the commandments.
    • n decad A set of ten objects; ten considered as a whole or unit.
    • n decad Specifically A period of ten consecutive years.
    • n decad In music, a group of ten tones, having precise acoustical relations with one another, arranged so as to explain and correct problems in harmony and modulation. It consists of two complete trines, the first based on the root or assumed starting-tone, and the second a perfect fifth above the first, together with two incomplete trines, one above and the other below the complete. It contains two heptads, which have a common cell (or fundamental group of tones). Compare duodene.
