The flugelhorn is the soprano instrument from the brass instrument family. In terms of shape, tuning and range, it is comparable to the trumpet, but deviating from it, it has a predominantly conical tube, another length and a mouthpiece with a deep cup. It is notated in B (rarely in C). (The flugelhorn in B flat is a transposing instrument because it sounds a big second lower than it is notated in the notation.)
