This Berkeleywind Flumpet is indeed a unique hybrid brass instrument, combining elements from both the trumpet and the flugelhorn. This combination gives it distinct construction and a sound profile that blends the bright, focused sound of a trumpet with the warm, mellow tone of a flugelhorn.

 specifically for jazz trumpeter Art Farmer, the Flumpet offers a special tonal versatility, making it a valuable instrument for performers seeking a broad expressive range. The instrument is commonly set in the key of B♭ and is compatible with a flugelhorn mouthpiece rather than a trumpet mouthpiece, which influences its softer, more rounded timbre.
