Pieces had a sense of balance with clear structures, for e.g sonata form. Use of major and minor keys with regular cadences. Lots of use of chords I, IV, V, II, VI. More varied dynamics than baroque. Typical classical orchestral instruments.

Woodwind Flute x 1 Oboes x 2 Clarinet x 2 Bassoon x 2

Sonata Form Can you recognise and describe these sections in detail?
Exposition (1-100) Opening section where all musical material is heard for the first time. First Subject (1-20) Presented in the tonic key (G minor) Bridge (20-44) Music modulates to a relative key Second subject (44-72) A contrasting theme in a relative key (Bb major) Codetta (73-100) Short section to bring the exposition to the end. Whole exposition section repeats.
Development (101-164)
Recapitulation (164-299)
A section for the composer to ‘develop’ Included to balance with the opening one or both ideas from the exposition. exposition. It explores the themes in many different ways and explores many keys steering clear of the keys heard in the exposition. In the set work, Mozart bases it on the opening 3 notes of the 1st subject. It becomes more chromatic and quickly passes through E minor, A minor, D minor, G minor, C major, F major and Bb major. (Notice each key goes up 4 notes)
First subject Presented in the tonic key (G minor). Exact copy of 1st 20 bars. Bridge (184-227) Changed slightly as its purpose is no longer to modulate the music to another key. This time keeps the music in the tonic key of G minor. Second subject (227-260) Now stated in the tonic key (G minor) Coda (260-299) Similar to codetta but extended to end the piece. The last 6 bars are the same as the last 6 bars of the exposition.
