ModernSee also: Properties of musical modes
Although many of the names of modes in modern music theory are the same as names used by the ancient Greeks for their harmoniai, they do not represent the same sequences of intervals found even in the diatonic genus of the Greek octave species. In the modern western conception, a mode encompasses the same set of diatonic intervals as the major scale. However, a different "tonic" (central tone) is used, resulting in a different sequence of whole and half steps above it.
By definition, all major scales use the same interval sequence T-T-s-T-T-T-s, where "s" means a semitone and "T" means a whole tone (two semitones). From the modal point of view, this interval sequence is called the Ionian or Major mode. It is one of the seven modern modes—seven because only seven diatonic notes can be used as the tonic. Taking any major scale, a new scale is obtained by taking a different degree of the major scale as the tonic. With this method, from each major scale it is possible to generate six other scales or modes, each characterized by a different interval sequence:
For the sake of simplicity, the examples shown above are formed by natural notes (also called "white-notes", as they can be played using the white keys of a piano keyboard). However, any transposition of each of these scales is a valid example of the corresponding mode. In other words, transposition preserves mode.

Famous quotes containing the word modern:
“The American Constitution, one of the few modern political documents drawn up by men who were forced by the sternest circumstances to think out what they really had to face instead of chopping logic in a university classroom.”
“A modern fleet of ships does not so much make use of the sea as exploit a highway.”
“The way in which modern German poetry follows theories reminds me of pupils who, scolded by their teacher for their insubordination, justify themselves by saying that they invented new rules of propriety according to which they are quite well- behaved.”
