Bach / Valter / Jourdan - Sonatas For Traverso & Clavier Music CD

In musicology, it has always been difficult to name the transitional period after the Baroque. Terms such as "sentimentalism", "Sturm und Drang" or "pre-classical" are usually borrowed from other art forms and are potentially fraught with judgements or preconceptions.
