An air flow valve positioned along the air flow path in a wind instrument. The valve includes three air conduits and is shiftable between a first position wherein the air flows substantially straight through the main air passage to the bell, and a second position wherein the air flow is diverted to a slide loop and thence back to the main air passage. The valve includes a manual actuator which is easily accessed by the musician to shift the valve between its first and second positions during playing.
