In Schenkerian analysis, the primary tone or head tone ((ドイツ語:Kopfton)) is the starting tone of the fundamental line. The fundamental line itself originates as an arpeggiation of the tonic chord, filled by passing tones: :In accordance with the arpeggiation from which it stems, the fundamental line exhibits the space of a third, fifth, or octave. These spaces are filled by passing tones.〔Schenker, Heinrich (1979). ''Free Composition'', § 5.〕 The primary tone therefore necessarily is one of the higher tones of the tonic chord, , or . The fundamental line descends from its primary tone to the tonic, : :To man is given the experience of ending, the cessation of all tensions and efforts. In this sense, we feel by nature that the fundamental line must lead downward until it reaches , and the bass must fall back to the fundamental.〔Schenker (1979), § 10.〕 ==Sources== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「primary tone」の詳細全文を読む スポンサード リンク
