Your playing is solid and reliable as always, sensitive without being sentimental (which is extremely important with Field, to avoid it sounding saccharine).
Could you please explain, why it is in your opinion extremely
important with Field not to play it sentimental? Any problem with the mood of beeing sentimental itself or does it concern the interpretation especially of this Field Nocturne?
Regarding avoiding to let it sound like saccharine (I like your comparison with saccharine!), one should ask what the appropriate mood of the special piece is. From the harmony and melody this Field Nocturne comes very simple, if not to say trivial too me. Field was known to have had a marvelous soft touch (IIRC what contemporaries said in the Eigeldinger book). All in all isn't it a valid question: IS this Nocturne like saccharine both from composition and from what we know how the composer's playing was known for? So if it appears from the composition so, why not play it like saccharine, Clayderman like, sentimental? If not those kind of pieces, which classical piano pieces then to play like saccharine? None?
