When Mozart Mourned: Violin Sonata No. 21 in E minor, K.304
When we think of Wolfgang Amadeus Mozart, words like “genius” and “brilliance” often come to mind. His music is often associated with clarity, elegance, humor, and joy. But behind that image was a young man who experienced deep loss.
In 1778, while in Paris, Mozart faced one of the most painful moments of his life: the death of his mother. Far from home in Salzburg, he was alone in his grief. Around that time, he wrote this sonata—his only violin sonata in a minor key.

A composer’s work is often deeply tied to their life, but in this piece, that connection feels especially intimate.
This sonata, written in two movements, carries a quiet, contained tension—grief that never quite breaks open, but lingers just beneath the surface. As a pianist, the second movement (starting at 7:22 in the video below) is one of my favorite moments to accompany—restrained, yet deeply profound.
Now, listen to the performance below, and take a moment to feel what Mozart might have been carrying in this music.
