•Pianist Jura Margulis recorded the present Schubert CD on a modern grand piano equipped with the built-on “sordino pedal” extension. Around the mid-19th century, this possibility of altering and extending the sound had largely disappeared from the canon of various pedal functions, but it was retained in Vienna until the early 20th century. Composers call this function “sordino” because the sound modification is related to the mutes of the string instruments.
