the use of the terms melodeon ;& button accordion seem to depend on who you are anad where you come from. Yes I would agree that the bcc# is a button accordion but many, including the late Sir Jimmy Shand refered to BC c#d or BCC# boxes as a wee melodeon!. John Kirkpatrick uses the term British Button BOx,. Irish terminology is that all button boxes are button accordions exept the one row which is a melodeon. Many english plaayers (&non players!) refer to the lot as melodeons. does it realy matter whether you call it a melodeon or a button accordion with 2 rows of accidentals, at the end of the daay it is still going to be BCC# unless somebody designs one in ,say, D with 2 rows of odds & sods.The possible permutations are considerable but each one so made would only be playable (without a great deal of learning) by its creator. The BCC# on the other hand is definately a fully paid up member of the melodeon family and could be the answer for those who require a fully chromatic push pull box rather than trying to sort of add chromatic bits to a DG

some bugger must have some views on this
