Symphony no. 25 in G minor, K.183

The Symphony No. 25 in G minor, K. 183/173 dB, was written by the then 17-year-old Wolfgang Amadeus Mozart in October 1773, shortly after the success of his opera seria Lucio Silla. It was completed in Salzburg on 5 October, a mere two days after the completion of his Symphony No. 24. Its first movement was used as the opening music in Miloš Forman's biographical film Amadeus.

This is one of only two symphonies in minor key that Mozart ever composed, both in G minor, referred to as the "Little G minor Symphony". The other is the No. 40, which is named the "Great G minor Symphony" since it is significantly longer than this one and has a larger scoring.

A typical performance of the symphony would take roughly 20 minutes.
