If the minuets alone of the two symphonies be compared, it will be acknowledged that an artist who within such confined limits can produce impressions of delicate wit and humour on the one hand, and of gloomy discontent and agitation on the other, has a full mastery of the forms and capabilities of instrumental music.

The symphonies of that time do not, as a rule, attempt to express passion or tragic emotion. They were, with few exceptions, intended to promote social enjoyment; consequently their essential characteristics are animation and brilliancy, or else calm serenity. The composer concentrated his efforts on the form and mechanism of his composition; to express deep feeling or the secrets of his own heart would have been alike impossible to him as an artist and contrary to the spirit of the time. A sharp line of division was drawn in theory and practice between human and artistic emotions, and any display of subjective emotion was discouraged. In the year 1774 "Werther" appeared; the strivings and conflicts of the time which produced it had their influence on music; but music had to pass through a longer and more arduous struggle before attaining to a like freedom of inspiration and expression.

The evident striving of the youthful Mozart to express himself and his innermost feelings in his music affords a significant indication of his development as an artist. Life had not taught him the lessons of passion and disappointment, and his nature was too sound and healthy to attempt to anticipate or represent emotions which had not touched him; he shows himself to us as he is.

The symphony was not then, as it is now, the grandest and most comprehensive form of orchestral music. The first place was given to the so-called serenata, a name originating in the circumstances of its composition, and scarcely applied to a fixed or well-defined form. The serenata was distinguished from the symphony in its narrow sense by greater variety and wealth of ideas and treatment. Several instruments are often grouped together in different combinations, THE SERENADE. and solo instruments are variously employed; also the number of separate movements often reaches as many as eight.

For the arrangement and manipulation of the movements the perfected forms of the symphony are employed, but with numerous modifications.

Serenades were introduced and sometimes also concluded by a march (39, K.). This was concise in form and simple in treatment, very often without even a trio; it was generally lively and cheerful. The detached marches by Mozart which are preserved were doubtless intended for introductions to serenades; they were often transferred from one to another, and so were written separately.

The minuet is almost invariably inserted between each andante and allegro, and therefore occurs two or three times in the symphony. The omission of all the other forms of dance music, so amply represented in the suite, is a proof that this form of instrumental music was not intended for practical use, at least in this juxtaposition. Variations were sometimes made in the character of the minuets by changes in the instrumentation, more especially in the trio. Several trios were frequently given to one minuet with appropriate instrumentation, making use of obbligato violins (185, 203, 204, 250, K.), flutes (204 K.), trumpets (250 K.), and sometimes the stringed instruments alone (100, 250, K.).

A grand allegro in two parts, as a commencement, and an allegro or presto at the close, sometimes introduced by a short adagio, form the main substance of the serenade as well as of the symphony, and the movements are similarly treated. The slow movement between them is in its turn between two minuets (62 K.), and there are sometimes two slow movements, each with a minuet appertaining to them (99 K.), and characterised by varied instrumentation. As time went on, an allegro was inserted between the two slow movements, which, however, was rendered distinct from the two principal quick movements by its lighter colouring and tone; the instruments, too, are grouped with more diversity. For instance (185 K.), the oboe and horn are employed obbligato in the first andante and the INSTRUMENTAL MUSIC. following allegro, and in the second andante flutes are combined with the stringed instruments.

A singular use is sometimes made of obbligato violins in the serenade (185,,203, 204, 214, 215, 237, 239, 250, K.). After the first allegro, the solo violins lead in three movements, viz.: andante, minuet, and allegro (rondo, 250 K.) which are in a measure complete in themselves, and form, apart from their surroundings, a complete symphony. The expression "finalmusik," which frequently occurs in Mozart's letters, seems to prove that these lengthy compositions, with their concerted solo instruments, formed the conclusion of the concert. The "concertantsymphonie" of the two last serenades belonging to 1774 and 1775 (204, 250, K.), are conspicuous from their peculiar instrumentation. In the other movements the usual oboes, horns, and trumpets are used as accompaniment to the obbligato violins, flutes, horns, and bassoons, and in the last movement especially the combination and treatment are quite modern. These two serenades show altogether a marked improvement on the earlier ones, which do not essentially differ from symphonies. The orchestra is firmly handled, and the orchestral subjects freely elaborated. Each of the many movements of the last serenade is worked out as carefully and lovingly as if it were the only one, and the ideas and motifs are so full of meaning and of jovial good-humour that it is impossible not to feel that Mozart has here put forth his best powers.

A short serenata (239 K.), consisting of a march, minuet, and rondo, interrupted by a short adagio, was written in January, 1776, for stringed instruments and drums only. A sort of chorus of two solo violins, accompanied by violas and violoncelli, is opposed to another, composed of two violins, viola, and violoncello, with the drums, all treated as tutti parts. Such admirable use is made of the contrast and combination of the two choruses, of the tutti parts and of varied sound effects, such as pizzicato, &.c., and even the drum is so skilfully employed, that this little work has taken a highly original colouring; with true tact the separate movements are made short, in order that the SERENADES—CASSATIO, 1771. singular charm of the piece may not suffer from the fatigue of the ear.[ 36 ]
