7, Ineffable Name : the unspeakable name of God.
Mysterious names of the Deity occur in other religions
besides the Jewish.
23. Rome's dom^ : it has been customary to illuminate
the dome of Saint Peter's on Easter Sunday and other
important festivals.
34. Protoplast: the thing first modelled from which
copies are imitated.
52. Out of three sounds he frame ^ not a fourth sound,
but a star J etc. : if you were to mix three colors together,
the result would be a fourth color in which the individu-
ality of the first three colors would be sunk ; but if you
mix three sounds together in a chord, the result will not
be a fourth sound, but a wonderful harmony of all three,
partaking of the individuality of each, and this is done by
combining tones chosen from nature's chaos of sounds
through the creative power of the artist.
91. Common chord: consists of the fundamental, with
a major (four semitones), or minor (three semitones) third,
and a perfect fifth (seven semitones) over it.
93. Ninth : if major, contains an octave and two semi-
tones ; if minor, an octave and one semitone. These
last lines of the poem, stripped of their symbolic mean-
ing, may be taken as an exact explanation of a simple
harmonic modulation. Suppose Abt Vogler, when he
** feels for the common chord," to have struck the chord
of C major in its first inversion, i.e, the third, E, in the
bass, the fifth, G, at the top 5 now, ** sliding by semi-
tones," that is, playing in succession chords with the
upper note a semitone lower, he would come to the chord
A, E, C, which is the (minor) lomc cYvox^ oi ^'t vaSst ^
