Counterpoint is still used especially in thematic development but is of secondary importance. Contrapuntal forms were generally abandoned although it was used sparingly and for specific purposes.
Harmony:
On the whole, there is less harmonic complexity and ingenuity in the classical period with no significant harmonic developments occurring until the time of Beethoven, although slow harmonic progression was among the most striking features that distinguished harmony after about 1730 from that of the Baroque era. Many passages in instrumental music consisted solely of principle triads. Seventh chords were used sparingly and ninth chords not at all whilst tonic-dominant harmony, IV-V-I harmonic progressions and classical cadential progression IIb-V-I were used frequently as the use of strong cadential progression frequently compensated for the use of chromatism in terms of tonality. The use of chromaticism for expressive effect was common. This was usually melodic chromaticism without affecting the underlying plain harmony. In its simplest form, it occurs in unaccented passing or auxiliary notes. Melodic chromaticism was used to compensate for the underlying harmonic plainness (especially in Mozart). Extensive modulations (equivalent to the use of dissonance by Baroque composers) were used to build longer arches of tension and release, and the borrowing of one or two chords from the tonic minor key or modulating to the tonic minor (major to minor shift was typical of Mozart and Schubert and only used in Vienna) were used.
Phraseology:
An aspect of formal clarity is the evident clarity of phraseology. On the whole, the phrases in classical music are shorter and more regular. Themes are made of very short fragments cast in 4 or 8 bar phrases and the repetition of short phrases became the characteristic of stile gallant, as opposed to a long uninterrupted stream of music in the Baroque period. Classical melodies usually fall into even phrases, and were often organized into symmetrical ‘question and answer’ structure.
Orchestration:
The basis of modern orchestration and instrumentation was established in the Classical period. Instrumental combinations became standardized. The flute and solo voice was used frequently, the roles of the harpsichord and string instruments were reversed and the piano, with its ability to produce gradations of dynamics, became the most important solo instrument for Classical composers.
Dynamics:
Composers in this period paid considerable attention to effects of loud and soft and an enriched use of rhythm and silence was used. There was also the use of dynamic shading, of crescendo and diminuendo as opposed to the baroque use of contrasting levels (ripieno against concertino)
Mood:
Establishing a single emotional quality and maintaining it throughout a composition seemed constricting to the younger composers, and so the mood of music was changeable in the same piece, with different moods in close succession existing in Classical pieces. With the contrasting themes of the sonata form, this thematic dualism became an essential structural element in Classical music as opposed to the constant moods and the principle of the basic affection of Baroque music.
THE CLASSICAL CONCERTO
The classical concerto is a three-movement form based upon the exchange of material between a solo instrument and the entire orchestral ensemble (tutti).
Because it is a modified version of the classical sonata-allegro form, the first movement of the classical concerto begins with an exposition consisting of 3 main parts:
- Opening tutti- principle themes are introduced, ends in the tonic key
- Entrance of the solo instrument followed by an exchange of material
- Short tutti section to close the exposition.
The development is usually short and leads through various keys back to the tonic. The Recapitulation is basically a repetition of the exposition, only shorter, and with the second tutti section ending on a six-four chord (tonic chord with the fifth in the bass). The sole instrument then plays a cadenza- written by either the composer himself or the performer or someone else or was improvised by the performer, as was the case in most classical concertos. A brief tutti section, with or without the solo instrument to conclude the movement, then follows this cadenza.
Usually in some sort of enlarged song form, a first rondo or a variation form, the second movement of the classical concerto is less virtuosic and more ornamental than the first movement. The cadenza is rarely used in the andante movement.
For a finale, the third and last movement is in a fast tempo, and, like the last movement of the classical symphony, it is usually some sort of rondo form. A short cadenza is occasionally used.
