Abstract: A valve block for a valve assembly of a wind musical instrument, said valve block comprising a monolithic structure having a plurality of parallel and linearly spaced apart valve bores extending at least partially therethrough and for receiving a corresponding plurality of valve pistons therein an air ingress port extending through the valve block from external of the valve block and providing fluid communication between external of the valve block and a first valve bore; an air outlet port extending through the valve block from external of the valve block and providing fluid communication between external of the valve block and a further valve bore; transverse connecting passageways for providing fluid communication between adjacent valve bores; and a plurality of pairs of tuning section ports with each pair extending through the valve block from external of the valve block and providing fluid communication between external of the valve block and a valve bore.

Abstract: A valved wind instrument including a tubular body having a tuning section, a lead pipe connected to a first end of the tuning section and a bell pipe connected to a second end of the tuning section, said tubular body being configured to allow a vibrating column of air to pass therethrough; wherein the tuning section includes an air inlet port for receiving air flow from the lead pipe at the first end, an air outlet port for delivering said air flow to the bell tube at the second end, a plurality of user operable valves; wherein each valve of said plurality of valves is in fluid communication with an adjacent valve by a first tubular portion so as to provide fluid communication between the inlet port and the outlet port, and wherein each valve of said plurality of valves is user moveable between a first position and a second position and each so as to increase the air pathway length between the inlet port and the outlet port by way of a second tubular portion; and wherein each second tubular portions is coplan
