"It is not wonderful," said she, in answer to his expression of astonishment, "it is not even difficult. There is an art in doing this, but, when you once know it, you find no trouble. It is rhythmic prose in a series of lines. Each line must contain a thought. Langhetti found no difficulty in making rhyming lines, but rhymes are not necessary. This rhythmic prose is as poetic as any thing can be. All the hymns of the Greek Church are written on this principle. So are the Te Deum and the Gloria. So were all the ancient Jewish psalms. The Jews improvised. I suppose Deborah's song, and perhaps Miriam's, are of this order."
"And you think the art can be learned by every one?"
"No, not by every one. One must have a quick and vivid imagination, and natural fluency--but these are all. Genius makes all the difference between what is good and what is bad. Sometimes you have a song of Miriam that lives while the world lasts, sometimes a poor little song like one of mine."
"Sing to me about music," said Brandon, suddenly.
Beatrice immediately began an improvisation. But the music to which she sang was lofty and impressive, and the marvelous sweetness of her voice produced an indescribable effect. And again, as always when she sang, the fashion of her face was changed, and she became transfigured before his eyes. It was the same rhythmic prose of which she had been speaking, sung according to the mode in which the Gloria is chanted, and divided into bars of equal time.
Brandon, as always, yielded to the spell of her song. To him it was an incantation. Her own strains varied to express the changing sentiment, and at last, as the song ended, it seemed to die away in melodious melancholy, like the dying strain of the fabled swan.
"Sing on!" he exclaimed, fervently; "I would wish to stand and hear your voice forever."
A smile of ineffable sweetness came over her face. She looked at him, and said nothing. Brandon bowed his head, and stood in silence.
Thus ended many of their interviews. Slowly and steadily this young girl gained over him an ascendency which he felt hourly, and which was so strong that he did not even struggle against it. Her marvelous genius, so subtle, so delicate, yet so inventive and quick, amazed him. If he spoke of this, she attributed every thing to Langhetti. "Could you but see him," she would say, "I should seem like nothing!"
