Shape notes are a music notation designed to facilitate congregational and community singing. The notation, introduced in 1801, became a popular teaching device in American singing schools. Shapes were added to the note heads in written music to help singers find pitches within major and minor scales without the use of more complex information found in key signatures on the staff. Shape notes of various kinds have been used for over two centuries in a variety of music traditions, mostly sacred but also secular, originating in New England, practiced primarily in the Southern region of the United States for many years, and now experiencing a renaissance in other locations as well. == Shape notes == The idea behind shape notes is that the parts of a vocal work can be learned more quickly and easily if the music is printed in shapes that match up with the solfège syllables with which the notes of the musical scale are sung. For instance, in the four-shape tradition used in the Sacred Harp and elsewhere, the notes of a C major scale are notated and sung as follows: A skilled singer experienced in a shape note tradition has developed a fluent triple mental association, which links a note of the scale, a shape, and a syllable. This association can be used to help in reading the music. When a song is first sung by a shape note group, they normally sing the syllables (reading them from the shapes) to solidify their command over the notes. Next, they sing the same notes to the words of the music. The syllables and notes of a shape note system are relative rather than absolute; they depend on the key of the piece. The first note of a major key always has the triangular Fa note, followed (ascending) by Sol, La, etc. The first note of a minor key is always La, followed by Mi, Fa, etc. The first three notes of (any) major scale – fa, sol, la – are each a tone apart. The fourth to sixth notes are also a tone apart and are also fa, sol, la. The seventh and eighth notes, being separated by a semitone, are indicated mi-fa. This means that just four shapenotes can adequately reflect the "feel" of the whole scale. 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「Shape note」の詳細全文を読む スポンサード リンク
