This doesn't sound a million miles from one of Chopin's Nocturnes and Chopin was of course a great admirer of Bellini and strove, particularly in his Nocturnes, to recreate the seamlessness of Bellini's long, vocal lines.
Interestingly, Claudio Arrau used to play his students records of Callas singing Bellini to help them in their understanding of Chopin's music.
