Samples of four styles of overtone singing, or throat singing, that are traditionally performed in Altai (Sygyt, Qargyraa, Kh.mei, and Qay) were studied. Spectral analyses of the digitized singing samples showed that these different styles have certain acoustic characteristics in common. There seems to be a stylistic continuum from a traditional (western-like) singing style to pure overtone singing. In the Sygyt style overtone melodies are produced by selectively amplifying overtones especially in the frequency area normally occupied by the F2 of vowels. In Qargyraa and Kh.mei melodies are produced in a similar way by amplifying certain overtones, but in addition there is a prominent high-frequency component giving these styles their characteristic timbre. The peculiarity of the epic Qay style is the use of a similar high-frequency component simultaneously with clearly articulated words, although Qay singers can sometimes switch between normal articulation and overtone melody production within one song.
