The tubing for each valve must be the correct length for the key of the instrument. How can pressing 1 valve adjust the other 3 valves' tubing length to play in tune with each key possible. I think either the valves are not used in the fashion described, or it doesn't work. Correct intonation would be impossible as it is described. Do I not understand something here?
