So far we have considered musical style in relation to isolated strains or melodies: and thus have led up to the more important question of its nature in the range of a continuous composition. It is obviously easier to write a good sentence than a good paragraph or chapter, even though all three are amenable to the same laws: and we can find many an artist who, like Horace's coppersmith, has skill enough in details, but remains
Infelix operis summâ, quia ponere totum Nescit.
Indeed, the preservation of balance and unity in a large work is an achievement that requires high gifts cultivated by long and patient training: every cadence gives a hostage to fortune, every phrase offers a pledge that must ultimately be redeemed. It is not surprising that composers have often been too fully preoccupied with the elaboration of single points to notice the due inter-relation of parts by which style in the whole is constituted.
For instance, there can be no question of Grieg's genius. His lyric pieces for the pianoforte are almost uniformly charming: his songs are among the greatest possessions of the art. But as soon as Grieg attempts to fill a larger canvas, his imperfections of style begin to appear, and the work becomes either incoherent, as in the String Quartett, or monotonous, as in the first two numbers of the incidental music to _Peer Gynt_. Gounod, again, has some admirable qualities, but among them is not included any great gift for uniformity, beyond the limits of a Berceuse or a Serenade. The 'Calf of Gold' song in _Faust_ opens with a magnificent phrase, and then degenerates into an anti-climax of pure irrelevance. The choruses in the _Redemption_ and the _Mors et Vita_ set out, for the most part, with a pompous fugue exposition, and discard counterpoint at the moment when its difficulties begin. Grant that the change of manner is due to deliberate choice and not to deficiency in technical skill; no plea of purpose can palliate the error. It would be just as reasonable for a dramatist to write the first act of his tragedy in Elizabethan English and drop to the nineteenth century for the other four.
We shall find a more interesting example if we compare the two versions of Brahms' B major Trio. In the first, possibly misled by an apparent analogy from Beethoven,[10] Brahms allowed himself to spoil the opening movement with an incident of sheer incongruity: in the second he has completely rewritten the passage and reduced it to entire harmony with its surroundings. Not that the latter version is deficient in contrast, but it makes contrast subservient to coherence. And it is certainly a striking fact that the great master should have recalled his early work in order to correct the one offence against organism of style, which it may be held to contain.
