The Flumpet was designed in 1989[2] and borrows the three piston valve design of both the trumpet and flugelhorn and shares the same instrument length of a trumpet. The curves on the end of the Flumpet have a resemblance to shepherd's crooks. The mouthpiece is deeply conical which tapers slightly, as opposed to the trumpet mouthpiece which has an extreme taper to create a bowl shape. The sound of the Flumpet is described as thicker and richer than a flugelhorn and more mellow and rounded than that of a trumpet. During its creation, metal-worker David Monette wanted to produce an instrument that broke design barriers but ultimately maintained its usefulness.[5]
The Flumpet has been described as "capable of both warmth and sharp attack", taking advantage of the softer sound produced by the flugelhorn, advantageous in smaller and more intimate venues, whilst still being capable of producing the more familiar harder tones of a trumpet.[6] The tone has been described as having "characteristics of a flugelhorn, but not nearly as brittle. It has the response of a cornet, but again the sound quality is broader and more resonant."[4]
