After dinner I went again to hear the boys of S. Onofrio at the Franciscans’ church […] I heard a Litany here by Durante: the rest of the music, which was but young, was by the young man who beat time. The instrument I took before for a clarinet is here called voce humana; ‘tis an agreeable tone, has a great compass but was not well played on. A concerto on the violin was introduced where hand and fire were discovered but no taste or finishing.
