Absolutely not! OK he didn't inspire the unification of Italy as Verdi is said to have done with the initials of his surname standing for Vittorio Emmanuele Re d'Italia. and he didn't write La Traviata or Va Pensiero. But he was an astonishingly skilled musical dramatist with a gift for characterisation and beautiful vocal writing. All his major operas include drop dead gorgeous hit numbers. Try this lot:
In Madama Butterfly we have the heart rending 'Un bel di' as the deserted Butterfly awaits her traitorous lover
And in Turandot we have perhaps the greatest tune of all with 'Nessun Dorma'
'Hats off, a genius' as Schumann said about Chopin. but we should all say about Puccini!
