THE RECENT REVOLUTION IN ORGAN BUILDING

CHAPTER I.

AS IT WAS IN THE BEGINNING.

"The Organ breathes its deep-voiced solemn notes,
The people join and sing, in pious hymns
And psalms devout; harmoniously attun'd,
The Choral voices blend; the long-drawn aisles
At every close the ling'ring strains prolong:
And now, of varied tubes and reedy pipes,
The skilful hand a soften'd stop controuls:
In sweetest harmony the dulcet strains steal forth,
Now swelling high, and now subdued; afar they float
In lengthened whispers melting into cadenced murmurs,
Forming soft melodious strains, and placid airs,
Spreading gently all around, then soaring up to Heav'n!"
--_Dryden_.

The origin of the pipe organ is lost in the mists of antiquity.
Tradition hath it that there was one in Solomon's Temple at Jerusalem,
the sound of which could be heard at the Mount of Olives. It has the
honor of being the first wind instrument mentioned in the Bible
(Genesis iv, 21), where we are told that "Jubal is the father of all
such as handle the harp and the organ." The Hebrew word here is
_ugab_, which is sometimes translated in the Septuagint by cithara (the
ancient lute), sometimes by _psalm_, sometimes by _organ_. Sir John
Stainer ("Dictionary of Musical Terms," p. 444) says: "It is probable
that in its earliest form the _ugab_ was nothing more than a
Pan's-pipes or syrinx, but that it gradually developed into a more
important instrument." The passage, however, shows that the ugab was
known in the time of Moses, who was "learned in all the learning of the
Egyptians."

The flute, a component part of the organ, is one of the most ancient of
musical instruments. We find it pictured on the walls of early
Egyptian tombs, and specimens of it, still in playable condition, have
been unearthed and can be seen in our museums. Some of them were
double, as shown in the illustration. Side by side with t
