I want to know the answer to the following question:
According to J. Barrie Jones who was the only true successor to Chopin?
All the background I'm provided with is that "Polish composers of the following generation included virtuosi such as Moritz Moszkowski, but, in the opinion of J. Barrie Jones, his "one worthy successor" among his compatriots was Karol Szymanowski (1882–1937).". Is that enough to answer the question?
