by one or two instruments only e.g. solo piano or double bass and piano. A Sonata consisted of three or four movements that contrasted in both tempo and key, but relate in thought and work seamlessly together.
             An example of the construction of a normal 4 movement Sonata may go like this:
             Andante, adagio, largo ~ a slow, rhythmic and lyrical movement
             Scherzo ~ light and graceful movement often in a dance form
             Each movement in Sonata form has three parts:
             Exposition ~ Introduces the main theme of group of themes
             Development ~ The composer varies the themes, combines them, breaks them into smaller sections or plays them in different keys.
             Recapitulation ~ Restates the original theme or themes.
             Coda ~ can be added as a conclusion to a movement and comes after the Recapitulation
             The Classical Orchestra although different from modern examples was fundamentally the same. The small sized groups of the Baroque period were surpassed and orchestras made use of more than 40 players in some cases. The orchestra generally featured the string section which played majority of the melodic material in the work. The woodwind usually consisted of two flutes, two oboes, two bassoon and nearer to the end of the classical period the clarinet. The Brass section would include two trumpets and two horns. The percussion had two timpani plus other hand held instruments.
             The classical orchestra has gone on to shape modern orchestras that can have in excess of 100 players and play modern works as well
