Features B flat TRUMPETS "CONCEPT" TT Selmer Paris Description Product Description "CONCEPT" TT B flat TRUMPETS Power and finesse. The "Concept TT" is an artistic offer which complements the "Chorus" models, greatly enriching the Selmer Paris B-flat trumpet line. A design based on the "TT" technology ("Twin Tube" or double tube mouthpipe) gives it exceptional acoustic qualities : a direct, centred sound, very open harmonics, excellent response and a wide dynamic range. All these elements contribute to remarkable flexibility and make it particularly suitable for musicians playing in orchestras and larger or smaller groups (soloist or section). The quality of its functional elements (slide adjustment, valve functioning and grip) and the care taken in making the "Concept TT" result in a world class trumpet.
