Bandoneon vs accordeon sound in Instrument Construction & Repair Posted September 26, 2019 · Edited September 26, 2019 by inventor Left a couple of words out of reply There is one factor about the construction of the Bandoneon which alters the timbre. This is placing the reeds on continuous rather than individual reed plates. Russian "Bayan" accordions are also constructed in this way which gives the timbre that Russians favor. I suggest you find someone who plays a Russian Bayan and see if this is what you are looking for. I once had a concertina made in Moscow by a bayan accordion maker which had all the reeds of each side on a single plate. This instrument had a timbre much closer to the sound of a traditional concertina than a hybrid accordion reeded concertina. Inventor.
