Paisiello is known to have composed 94 operas, which are known for their gracefully beautiful melodies. Perhaps the best-known tune he ever wrote is Nel cor più non mi sento from La Molinara, immortalized when Beethoven composed variations based on it. Paisiello also wrote a great deal of church music, including eight masses; as well as fifty-one instrumental compositions and many stand-alone songs. He also composed the Inno al Re, the national anthem of the Kingdom of the Two Sicilies. Manuscript scores of many of his operas were presented to the library of the British Museum by Domenico Dragonetti.
