首先，标准调弦的6到1弦各为：EADGBE。想将6到1弦调到DAD#FAD，即在标准调弦的基础上将6弦降一个全音，3弦降半音，2弦和1弦也是各降一个全音。4，5弦不变。搞定！

《奇迹の山》收录在专辑《奇迹の山》中。

作者简介：岸部真明(Masaaki Kishibe)是日本新生代的演奏家，日本指d吉他大师中川砂仁(Isato Nakagawa)的学生。其作品风格非常的多元化，既有优美清新的吉他独奏小品，又有另类的独奏作品，他于2003年参加了National Fingerstyle Guitar Championships，并获得了第2名的好成绩，展现了其非凡的实力。

同度效音法：

一弦空弦等于二弦五榀处。

二弦空弦等于三弦四榀处。

三弦空弦等于四弦五榀处。

四弦空弦等于五弦五榀处。

五弦空弦等于六弦五榀处。
