Sounds like a plan As for the extant descriptions of individual pieces I ve just been editing the article on his very best known compositions the two Romanian Rhapsodies and if the state in which I found it is anything to go by sources in English aren t worth much You might like to take a look at the edit history there For the rest Enescu was not an ethnomusicologist as Bart k and Kodl ly were and so it would be unreasonable to expect from him a deep knowledge of the rural folk music music of his country It is also frequently observed that he absorbed folk elements into his compositional style rather than actually quoting folksongs with a few exceptions mainly the two Romanian Rhapsodies Consequently I wouldn t get my hopes up about any great revelations about the presence of actual non gypsy Romanian folk music in Enescu s compositions
