The harmonies are often hideous, though no note in the entire quartet is without a logical justification in the new grammar. On the other hand, there are moments of ineffable beauty. Whatever the outcome, there can be no denying that the quartet has entered here upon a new stage, far removed from all other music. Only time can tell whether this is an advance, and then only by showing new work when this shall have proved itself a foundation on which to build.

Schönberg has since written another quartet (1907-8). It is not only shorter as a whole than the earlier one, but is divided by pauses into four separate movements. There is, however, a thematic relationship between all four; and the third movement—Litanie—occupies in the scheme the place of a Durchführung, a variation and weaving together of all the previous themes.

The first movement begins and ends in F-sharp minor, and there are two distinct themes: the opening theme (first violin), and, after a broad ritard, a second theme (first violin, sehr ausdrucksvoll). The time is measured yet often free. After a development of the two themes there is a fermata, and then a restatement of them; so that on the whole the movement is not difficult to follow, though the second half is complex and long.

The second movement (sehr rasch) is in the nature of a wild scherzo. The rhythmical motive with which it starts (cello, pianissimo) recalls the now ancient style of Wagner. There is no precedent for the following figure (second violin), which is one of the chief elements in this fantastical movement. It is taken up by viola immediately, while both violins present at the same time two equally important motives, one of which is a sort of syncopated shadow of the other. Then, etwas langsamer, the first violin and viola give out yet a fourth motive (in octaves) and out of these four, with many less audible, a cacophonous, spiteful tangle of sounds ensues. There is a Trio section (etwas rascher), and a return of the Scherzo. There is a short coda, sehr rasch, all instruments in unison (or octaves) until the last measures. Then the cello beats out the opening rhythmical figure, fortissimo, on D, the first violin shrieks G-C-sharp over and over again, the viola and second violin fall together through unheard of intervals. There is a hush, a roar, and a hush—a pizzicato note—unison—silence.

Both the third and the fourth movements bring in a soprano voice. The words are from Stephan George;[81] the titles: Litanei and Entrückung. Here Schönberg has gone beyond the string quartet, and here properly we may leave him. The instruments are busy during the Litanei with motives from the first and second movements. The voice is independent of them. There is enormous dramatic force in the climax at the words:

Wacht noch ein Schrei
Töte das Sehnen...
Schliesse die Wunde!
Nimm mir die Liebe
Gieb mir dein Glück.

In the last movement there is no appreciable form. There is no harmony, i.e., no regular sequence of keys, though the end falls on a common chord. Even the melody has gone on into a new world.

Schönberg’s style is fundamentally polyphonic, and is in that regard fitting to the quartet. In the use of harmonics and pizzicato he stands a little ahead of his contemporaries. If we can follow Schönberg in his new conception of form and harmony, we should indeed be reactionary if we hesitated longer to admit harmonics and pizzicato into the category of effects proper to quartet music. Moreover, the examples offered by such exquisite masterpieces as the quartets of Tschaikowsky, Debussy and Ravel must give to such procedures the sanction of good usage. That Schönberg’s material is symphonic in character only goes to prove that the whole question of form and style is at the present day one which no man can definitely answer.

But having admitted the influence of modern virtuosity and of the modern love of sensuous tone coloring into the realm of the string quartet, we face a new idea of the combination of the four instruments of one type. The old idea of the quartet was given fullest expression in the quartets of Beethoven. In the expression of that idea little progress has since been possible. The changes that have come have made of the quartet something like a chamber symphony in which effects of solid sound and of brilliant and pronounced colors predominate, music that has salt for the senses as well as meaning for the spirit. Hence it has lost that traditional quality of abstractness, which was pure and unalloyed, and has become poignant, fiery, pictorial or dramatic. We hear in it now the strumming of wild zithers, now the beat of savage drums, madness and ecstasy, chords that are plucked, chords that float in air, even confusion and riot of sound. The four instruments still remain, but the old idea of the quartet has become lifeless or has passed from among the present ideals of men.
