There are three main modes used in composition: dicot[7], called Durmoll (seen above), 5edo, and 10edo.

Traditionally the main triad in most classical and folk-style music is taken to be [0 3 6], or what is known here as the neutral triad. This triad on note X is called Xt. Degree arithmetic is assumed to be modulo 10. | ||
Neopentatonic melodies are traditionally written in the equipentatonic mode and have a strong folk-like sound. Traditionally, triads are placed to harmonize the melody such that they produce the most harmonious sound. Here are the rules for selecting a chord to harmonize some notes: | |||
* Use Xt or (X-6)t when there is only one note, X. | |||
* If there are two distinct notes a tone apart in the part you want to harmonize, use the 1st rule on the note which receives the most stress. | |||
* If there are three distinct notes each a tone apart use the triad corresponding with the root of the topmost or bottommost note (though the latter is rare). | |||
Nowadays neopentatonicism is more liberal and allows the (X-3)t triad for the first rule. | |||
Pieces or sections of pieces written in Durmoll or something similar have a strong resemblance to the music of the Classical period and traditional Western harmony is applied accordingly. Modern orchestral works from the Late Romantic onwards use both modes relatively equally. | |||
