The purpose of this article is to describe contrastively the realizations of the plain unmarked tone `Peongseong` and that of the marked tone `Geoseong` in the environment of [## -#] and [## - ^#] in detail. Here, the sign [^#] designates word boundary or pause, [##] phrase boundary, [#] open juncture respectively. Open juncture does not always appear physically, but exerts significant influence upon the realization of tones. While Peongseong /H/ is realized into [MH], and Geoseong, into [HH] in the environment of ## - #, in the environment of ## - ^# they are realized into [M] and [H] respectively. The [M] like this is the first half of normal Phyeongseong realzation [MH], on the other hand the [H] is the first half of normal Geongseong realization [HH]. Hence, we can designate such [M] and [H] as we introduced in the above as half-Phyeongseong and half-Geoseong respectively. Through such observation, we could describe various pitch patterns that we could examine.
