It was one of his two symphonies in G minor. The symphony was considered relatively unique among Mozart's music collection for its Sturm und Drang style. The whole first movement conveys feeling of intensity, stress, and even fright, however, we can hear from it that Mozart did not simply want to create a typical Sturm und Drang work that was just similar to those of other composers like Haydn. Apart from stress, and fright, there is also sound of peace, calm, and even hope. "Symphony No.25" is a great masterpiece of Mozart, and its consistent presence finally led to the greatest of his G minor utterances, "Symphony No. 40 in G Minor, K 550." .
The music's intensity and agitation start from the first note. The sudden violins concerto builds up the first theme, which sounds like putting people in a dangerous and unexpected journey with rainstorm coming. Starts from 24'' of the music, the strong violins suddenly stopped and are contrasted with a slow clarinet solo. The solo sounds more whimsical as if the composer was trying to add more darkness to the dangerous journey. The violin and clarinet combined builds up the Sturm und Drang atmosphere of the music. However, start from 43'' of the music, the violin concerto seems to sound happier and more positive. From this sound we can imagine a scene that someone who was previously lost in the dangerous and dark journey suddenly found brightness, and a way that he could get rid of the darkness. However, this anticipation suddenly fall from 1'11'' of the music. The strictly falling down of the scale crashed all the hope and ignited the fear again. Then from 1'26'' here started the second theme, which sounds more peaceful, much happier, much calmer. I think this theme is more like a happy memory that the man had during his dangerous situation. However, the peace only lasted for half a minute before the violins again start to play in explosive bursts.
