How many valves has a trombone have?

Answer 1

This depends whether you count all the slides, valves and springs etc. Simply, the tuba has a mouthpiece and the instrument. Otherwise, it has any number of slides, depending on make, same with the valves.

Answer 2

generally at least three. entry level tubas have the basic 3 valves - a half step lower, a full step lower, and a step and a half lower. more advanced tubas can have a fourth valve, which functions as a combination of the first and third valves, or two and a half steps lower. yet more advanced tubas can have a fifth or perhaps a sixth valve, which can be tuned to however many steps the player would like to have. more valves give the player more flexibility with regards to fingerings and intonation.

Answer 3

By definition, a valve is a device which switches a short piece of tubing in and out of the 'circuit' of a brass instrument. If the instrument, a Trombone, say, is 8' long, and the valve switches in an 8" piece of tubing, then the trombone will be 8'8" long with the valve actuated, and 8' long with the valve de-activated. There is another kind of 'valve', although it is actually more of a 'key': the spit-valve. This is a lever-activated hole cover, which, when opened, allows accumulated moisture to be drained from the tubing. You have to decide if the spit-valve counts as a valve for your purposes.

The trombone is a special case of the brass instrument family, in that it is played using a telescoping 'slide' to select the pitches. The standard tenor and alto trombone has no tube-switching valves at all, and one spit-valve.

The bass trombone often has a rotory valve (like the valves on the french horn) which switches in a considerable amount of tubing, switching the overall pitch by a fourth or fifth. In this case, the bass trombone has two valves, if you count the spit-valve as a valve.

There are also a variant family of trombones which use valves like the Trumpet, rather than the telescoping slide to select pitch-lengths. In this case, the valve trombone usually has three valves for switching tubing and the spit valve. A larger trombone, equivalent to the bass slide trombone, might also have one or two rotory valves for changing key as well, which would increase the number of valves to 5 or 6.

Answer 4

Bassoons don't use valves, they use finger holes, regular keys, and whisper keys.

Answer 5

Four, at least that's what the ones in my band have. I may be wrong
