NOT a bagpipe, but a general term used for the common mouth organ; Also called "Gaita boca" or "Harmônica"; According to one of the internet sources (AliExpress) it is "an essential part of Brazilian culture, especially in the Northeast"; Another website (Portalidea) informs us, however, that "In Brazil, in most states it is called harmonica or gaita, in the south of the country it is known as gaita de boca and in the northeast it is called realejo or vialejo".
