A refracting telescope which has been freed from the effects of chromatic aberration is called achromatic. The principle upon which its construction depends is that by combining lenses of different dispersive power the separation of the spectral colors in the image can be corrected while the convergence of the rays of light toward a focus is not destroyed.
In these each chord shows careful effort at color, and the work is chromatic enough to convince one that he has studied his Bach thoroughly. Among his massive compositions there are two that seem likely to win, as they surely deserve, a long life. These are the symphonic suite, "The Tempest," and the "Prodigal Son."
And the Murchisons had descended to face the situation. Lorne had by then done his part, and gone out into the chromatic possibilities of the day; but the sense of injury he had communicated to Advena in her bed remained and expanded. Lobelia, it was felt, had scurvily manipulated the situation her situation, it might have been put, if any Murchison had been in the temper for jesting.
In the religious, almost Gregorian, strain her voice was pure as a little child, but when she spoke of her renunciation and the music grew more chromatic, her voice filled with colour her sex appeared in it; and when the music returned to the peace of the religious strain, her voice grew blanched and faded like a nun's voice.
Liquids were of every colour, ices chromatic, and the scarlet of lobster made a luscious contrast with the shaded tints of salads. In the extreme background men were playing billiards at three tables.
Then came chromatic scales of colour; combinations meant to vulgarise the rainbow; sinfonies and fugues; the twittering of birds and the great peace of dewy nature; maidenhood in her awakening innocence; "The Dawn in June." The Master rested content. A week later came an order from Sybil, including "an entirely original ball-dress, unlike any other sent to America." Mr.
They watched my fingers and asked what kind of music it was that I was playing, where I had learned it, and a host of other questions. It was only by being repeatedly called back to the table that they were induced to finish their dinner. When the guests arose, I struck up my ragtime transcription of Mendelssohn's "Wedding March," playing it with terrific chromatic octave runs in the bass.
It ought not to have required much eloquence to convince us that Widnes is unlovely; the smell of it should have been enough. It is curious that we needed festoons of chromatic sentences to warn us that cruelty to children, even when profit can be made of it, is not right. But I fear some people really enjoy remorseful sobbing. It is half the fun of doing wrong.
Sharp dissonances, chromatic passing notes, suspensions and anticipations, displacement of accent, progressions of perfect fifths the horror of schoolmen sudden turns and unexpected digressions that are so unaccountable, so out of the line of logical sequence, that one's following the composer is beset with difficulties.
This is not an imaginary division of qualities, but a real one, the flamelike red color having a principle of warmth in itself; the blue and violet, a principle of cold and electricity. Thus we have many styles of chromatic action, including progression of hues, of lights and shades, of fineness and coarseness, of electrical power, luminous power, thermal power, etc."
