Arriaga was a hard working young man, and not only kept up with his studies but composed. His output was regretfully but understandably small, as he died a few days before his 20th birthday, possibly from tuberculosis.

The 3rd quartet in E-flat major shows the progress he was making in his musical thought. The three string quartets are the most well known of Arriaga's compositions and are represented on numerous recordings.
