 While Sax's family of saxhorns were invented at about the same time and the bass saxhorn is very similar to a euphonium, there are also differences—such as the bass saxhorn being narrower throughout the length of the instrument.The "British-style" compensating euphonium was developed by David Blaikley in 1874, and has been in use in Britain with the basic construction little changed since then.Modern day euphonium makers have been working to further enhance the construction of the euphonium.
