This Blackburn Eb/D Trumpet is built as an instrument to serve the needs of both the orchestral musician and soloist as well. This instrument features a heavy weight bell made of Ambronze, a metal alloy unique to Blackburn’s trumpets. Both Eb and D bells are the same profile as my C trumpet bell (MD19A24S). DM19 refers to the bell mandrel, A stands for ambronze, the bells are 24 thousandths of an inch and have a steel bell wire. I have used this instrument in brass quintet as well as playing Principal Trumpet with the HSO and Orchestra Kentucky on sections of Bartok’s Concerto for Orchestra, Holst’s Planets, and premier of Schwantner’s Chasing Light. I have also performed the concerti of Haydn, Hummel, and Neruda. The E-flat/D trumpet is an essential instrument of any professional trumpet player. Prior to acquiring the Blackburn, I played a Bach long bell Eb/D. It was an excellent all around horn as well. They do not play as easily as a Schilke, but the sound is easily adaptable to large and small works. It is up to personal choice.
