Pronounced 'shalloo moe', this is a small clarinet-like instrument with a deep tone. It has a cylindrical bore and single reed like a clarinet. Unlike a clarinet, though, there is no upper register and it only has a range of one and a half octaves. It looks a bit like a recorder as it has no bell. The chalumeau was first mentioned in writing in 1700 but the clarinet was developed from it around the same time. The chalumeau was probably developed from the recorder and existed in parallel with the clarinet until the clarinet's lower register was improved enough to make the chalumeau obsolete. (The clarinet's lower register is still called the 'chalumeau register').
