7TET

>}My favorite equal tempered scale is 7TET. It is a challenge because it
>}has so few tones but yet is unexplainably very interesting.

>Are you aware that traditional Thai (Siamese) music is performed in 7TET? The
>music uses pentatonic melodies and modulation (usually by fourth or fifth).
>Modulation is the primary reason any culture adopts equal temperament (I'm
>not sure if any of the African 5TET cultures employ modulation). A 20th
>century Thai style has developed that uses all 7 tones in the melody --
>analogous to the 12-tone style in the West.
