Published by Joseph Pugh (A0.1142874). The Kuhlo horn (also Kuhlo-Flugelhorn) is a small flugelhorn in Bâ™. This is a specially designed brass wind-instrument played using a deep bowled mouthpiece. Chief characteristics are its oval design and integrated, usually conical tubing. Kuhlo horns commonly are featuring a conical tuning slide, at the second curved pipe section after the rotary valves. This unique Brass Quintet arrangement exploits the rich deep tones of the horn. Feel free to use a regular flugelhorn or Bb trumpet for the part if you don't have a Kuhlo horn.
