The modern harp with double action is the only instrument with fixed tones, not determined by the ear or touch of the performer, which has separate notes for naturals, sharps and flats, giving it an enharmonic compass.
And this brings us to the only remaining subjects of importance in the science and art of harmony, namely, those of the tempered scale, enharmonicambiguity and just intonation.
Not every progression of chords which is, so to speak, spelt enharmonically is an enharmonic modulation in itself.
Melodies involving chromatic or enharmonic writing are much less suitable to the character of brass instruments.
In all of them a delicate and tasteful accompaniment, a rich and bold harmonic treatment--I need only mention the effective enharmonic changes in the andante of the B flat major sonata (454 K.
The harmonic treatment, and more especially the enharmonic changes, are of extraordinary beauty and depth, and occasion remarkable effects of suspense and climax.

The enharmonic mode is an artistic conception, and therefore execution in it has a specially severe dignity and distinction.
What is called lichanos in the enharmonic is at the interval of a semitone from hypate; but when shifted to the chromatic, it goes two semitones away; and in the diatonic it is at an interval of three semitones from hypate.
Beginning with the bottom range, let the arrangement be as described above in the case of a smaller theatre, but on the enharmonic system.
Thus, parhypate, which in the enharmonic is at the interval of half a semitone from hypate, has a semitone interval when transferred to the chromatic.
Klindworth accents the first of the bass triplets, and makes an unnecessary enharmonic change at the sixth and seventh lines.
Von Bulow is the only editor, to my knowledge, who makes an enharmonic key change in this working-out section.
That Chopin may lead to the development and adoption of the new enharmonic scales, the "Homotonic scales," I do not know.
Much wonder and admiration has been wasted on the Enharmonic scale by persons who have missed the true reason for the disappearance of the quarter-tone from our modern musical system.
The writers of lyric verse cannot vary the melodies of strophe and antistrophe, but whether they adopt enharmonic melodies, or chromatic, or diatonic, in all the strophes and antistrophes the same sequences must be observed.
For the legend runs that he composed melodies in the diatonic, chromatic, and enharmonic styles as antidotes for moods such as anger, fear, sorrow, etc.
The chromatic and enharmonic styles had been abandoned in theory, the portamento which the singers introduced into their chants being the only principle retained.
In the forty-ninth measure begins another chapter, in which we have a series of recitative-like phrases, the most of which end upon diminished chords and contain or suggest enharmonic modulations of extreme modern type.
To be sure, the violinist can make his intervals absolutely correct: he can play the enharmonic scale, which one using any of the instruments with fixed notes cannot do.
This is the enharmonic scale, having twenty-one notes.
Finally we have (6) more recently the Besson enharmonic valve system (fig.
The Lydian is certainly the Lydian Enharmonic species of the pseudo-Euclid; but we can hardly suppose that it existed in practical music.
The special fitness of the notation for the scales of the Enharmonic genus may be regarded as a further indication of its date.
It may even be that this sense of [Greek: harmonia] was connected with the use for the Enharmonic genus.

I frequently repeated this test, and indeed with the addition of all manners of difficulties: I extended it to the most divergent keys in which enharmonic changes were required, yet they never became embarrassed.
The enharmonic principle is almost too predominant,--an element that ought never to be more than occasional.
So it is likely that the enharmonic process of Franck led to the strained use of the whole-tone scale (of which we have spoken above) by a further departure from tonality.
This over-stress appears far stronger in the music of Franck's followers, above all in their frequent use of the whole tone "scale" which can have no other rationale than a violent extension of the enharmonic principle.
