The Baroque era witnessed the creation of a number of musical genres which would maintain a hold on composition for years to come, yet it was the Classical period which saw the introduction of a form which has dominated instrumental composition to the present day: sonata form. With it came the development of the modern concerto, symphony, sonata, trio and quartet to a new peak of structural and expressive refinement. If Baroque music is notable for its textural intricacy, then the Classical period is characterised by a near-obsession with structural clarity.
The seeds of the Classical age were sown by a number of composers whose names are now largely forgotten such as Schobert and Honnauer (both Germans largely active in Paris), as well as more historically respected names, including Gluck, Boccherini and at least three of Johann Sebastian Bach’s sons: Carl Phillip Emmanuel, Wilhelm Friedmann and Johann Christian (the so-called ‘London’ Bach). They were representative of a period which is variously described as rococo or galante, the former implying a gradual move away from the artifice of the High Baroque, the latter an entirely novel style based on symmetry and sensibility, which came to dominate the music of the latter half of the 18th century through two composers of extraordinary significance: Joseph Haydn and Wolfgang Amadeus Mozart.
