It is through this system of orchestral groups that Wagner has been able to enrich orchestral tone coloring, and to say everything he wishes to say in exactly the way it should be said. We cannot, for example, imagine that the Love Motive in “Die Walküre” could be made to sound more beautiful on its first entrance in the score than it does. Nor could it. In that scene 180 it is exactly suited to a solo violoncello, and to a solo violoncello Wagner gives it. In order, however, to produce a perfectly homogenous effect, in order that the violoncello quality of tone shall pervade not only the melody, but also the supporting harmony, he supports the melody with eight violoncellos, adding two double basses to give more sonorousness to the deepest note in the harmony. In other words he has made for the moment a complete orchestra out of nine violoncellos and two double basses, and produced a wondrously rich and thrilling effect—because, having a 181 beautiful melody to score, he knew just the instruments for which to score it. This is an admirable example of what technique accomplishes in the hands of a genius. Another composer might have used an orchestra of a hundred instruments and not have produced the exquisite thrill that Wagner with his magical orchestral touch conjures out of this group of violoncellos, a group within a group, an orchestra of violoncellos within the string band.

The woodwind instruments are capable of several similar subdivisions. Flutes, oboes and bassoons, for example, may form a group capable of producing independent harmony, so can the clarinets, and the same is the case with the brass instruments. One of Wagner’s most beautiful leading motives, the Walhalla Motive in the “Ring of the Nibelung,” is sounded on four trombones. In brief, then, the modern composer strives to constitute his orchestra in such a way that he secures as many independent groups, and as many little orchestras, as possible, not, however, for the purpose of using them independently all the time, but merely in order to do so occasionally for special effects or to combine them whenever he sees fit in order to enrich his tone coloring or weave his polyphony.
The grand divisions of the orchestra are the strings—violins, violas, violoncellos and double basses; the woodwind, consisting, broadly speaking, of flutes, oboes, clarinets and bassoons; the brass—horns, trumpets and trombones; and the instruments of percussion, or the “battery”—drums, triangles, cymbals and instruments of that kind.
The Prima Donna of the Orchestra.
The leading instrument of the string group, and in fact the leading instrument of the orchestra, is the violin. The first violins are the prima donnas of the orchestra, and one might say that it is almost impossible to have too many of them. The first and second violins should form about one-third of an orchestra, and better still it would be for the number to exceed that proportion. The Boston Symphony Orchestra, which has about eighty-one players, has thirty violins. Theodore Thomas’s New York Festival Orchestra in 1882, consisting of three hundred and fourteen instruments, had one hundred violins.
