다국어 초록 (Multilingual Abstract)

Sujecheon and Geomungo Sanjo Jinyangjo Ujo, which are classified as different genres, begin with a scale of La-do-re-mi-sol, modulate once, and end with a scale of Sol-La-do-re-mi. In this paper, the scales of these two pieces are compared by focusing on the two nuclear tones.
A nucleus is a note that provides stability and is used as a sustained note in a melody or at the end of a musical phrase. There are two nuclei, each a fourth or fifth within an octave. The one used at the end of a piece is called the final note, while another used in the middle is called the dominant note.
In the 1st movement of Sujecheon, the piece begins with the scale of La-do-re-mi-sol. The key of tunes is modulated a 4th degree upper tone in the third movement, and returns to the original key in movement 4, period 1. In the scale, the nuclear tones are two notes, La and re, and the two notes are in a perfect fourth relationship. La is the final sound and re is the dominant sound.
Movement 4, period 2 is the end of the piece and uses the Sol-La-do-re-mi scale. The core sounds are two notes, Sol and do, which are in a perfect fourth degree relationship. Sol is the finalis, and do is the dominant.
In the 1st movement of Sanjo Jinyangjo, composed by Nak-Jun Baek, the piece begins with the scale of La-do-re-mi-sol, modulates up a fifth in the second movement, and returns to the original key in the third period of the movement. In the scale, the nuclear tones are two notes, La and mi, and the two notes are in a perfect fifth relationship. La is the final and mi is the dominant.
The second and third passages in the third movement are the end of the piece, and use the Sol-La-do-re-mi scale. The core sounds are two notes, Sol and re, which are in a perfect fifth relationship. Sol is the fianlis, and re is the dominant.
