LARGE ORGAN- An exhibition took place on Thursday afternoon of last week of an organ of the largest class, in the new and splendid Presbyterian Church, University Place at the corner of Tenth street, New York, of which Dr. Potts is Pastor. A brief description will no doubt be acceptable to our readers. It is contained in an elegant Gothic case of black walnut, 35 feet high,18 feet front, and 15 in depth, and consist of four organs, viz: Great organ, choir organ, swell organ, and pedal organ. In all 32 stops. and nearly 1500 pipes. The diapasons in the great organ forming the bases of the tones of the instrument give great solidity, which, being enriched by the brilliancy of the other stops, and majesty of the trumpet, yield an effect at once awful an grand. From this grandeur the delicate dulciano breaks at a distance, swells upon the ear, and leaves the mind almost unconscious from whence the delightful tones issue. The flutes, hautboys, and cremonas resemble the instruments from which their names are derived, and when played upon with skill from a delightful variety, and afford a pleasing contrast to the solemn tones just described. It was performed on by a number of professional gentlemen, who spoke in highest terms of the instrument. The instrument is from the manufactury of Mr. Henry Erben, of New York.
Identified through a brochure published by Henry Erben c. 1874.
