From the Selmer website:
"'SIGNATURE' is a unique and unrivaled concept. The tone, a right compromise between roundness and presence, is a subtle mixing of sweetness and energy. A wide dynamic range facilitates pianissimo and unsaturated fortissimo, with a perfectly homogeneous tone over the various registers. A centered and easy emission provides a high level control."
