This instrument is in the family of brass instruments, more particularly low-brass instruments with many relatives. It is extremely similar to a baritone horn. The difference is that the bore size of the baritone horn is typically smaller than that of this instrument, and the baritone is primarily cylindrical bore, whereas this instrument it is predominantly conical bore. It is controversial whether this is sufficient to make them two different instruments The cylindrical baritone offers a brighter sound and the conical of this instrument offers a more mellow sound.
