Galant Harmonic Progression

These nine measures from Franz Danzi's Sinfonia Concertante in Eb major contain a typical harmonic progression found in the Galant period. This excerpt is split into two equal phrase. Each starting on a tonic chord, that is prolonged with a dominant chord, that lands on the tonic again, this time in first inversion. From there, there is a quick predominant chord, followed by a cadential motion to close each phrase. This type of progression was a very common way to start and end phrases during the eighteenth century.
