 note = {This thesis is intended to clarify the general features of the scales of the Folk Songs in Akita, using the
theory of the tetrachords of Japanese traditional music proposed by Koizumi.
In consequence of examining 320 notations, 4 conclusions as follows were brought out.
1) Most of all the Folk Songs in Akita are based on the Minyo (民謡) tetrachord, and Miyakobushi (都節)
tetrachord are rarely used. Folk Songs based on Ritsu (律) tetrachord are not many and have the tendency
to be combined with Minyo tetrachord.
2) It is more reasonable to regard the scales of Folk Songs as a combination of three kinds of tetrachord and
the frequent taransfar of the tonal center than regard as the one octave scale.
3) The method of using the borrowed tone and the modulation are based on the general rules of those of the
traditional Japanese music.
4) Perhaps getting the folk evaluations are useful method for the synthetic resarch for Japanese Folk song.},
