The following article is dedicated to observing fughetta genre in J.S. Bach’s works in the context of a composition-style system of his outstanding Italian predecessor. The object of the research is the identification of genealogical ’roots’ of Bach’s choral fughetta in relation to great fugal G. Frescobaldi’s instrumental genres (monothematic and polythematic), that is ricercares and canzonas.
