Trigger Trombone Terminology (Triggerology) :)

Terminology, parts, and other things you need to know about the trigger trombone:

Bell: The bell is the flaring end of the instrument from whence the sound comes. The taper of the bell effects the sound. The more gradual the taper, the darker the tone.

Bell Section: The section of the trombone that disconnects from the slide.

Bore: The bore is the inside width of the tubing of a trombone. The bore maintains a consistent width from the leadpipe, through the slide, and to the point that the bell section begins to flare. The wider the bore, the deeper the sound. A striaght tenor trombone can have bore size anywhere from .468″ to .509″ A closed wrap trigger trombone typically has a bore size of .525″ and an open wrap trigger trombone usually has a bore size of .547″. Also, the tubing of the F attachment often a little wider than the bore of the straight part of the trombone.

Dual Bore: Some trombones have slides where the upper bore is less wide than the lower bore. This allows for less air volume than is required for a larger bore horn while still sounding darker and mellower like a larger bore horn.

Embouchere: The way your lips form and press against the mouthpiece.

F Attachement: The extra tubing added to the bell section of a trigger trombone that changes the instrument from the key of B flat to the key of F.

Gooseneck: The crook in the tubing that goes from the slide to the bell.

Handgrip: The brace between the two sections of slide or the inner brace of the trombone.

Harmonic: Notes you can play on an instrument without moving valves or slides.

Intonation: The ability, or lack thereof, of an instrument to stay in tune.

Leadpipe: Also called the mouthpipe, the leadpipe is the small section of tubing between the slide and the mouthpiece. Most leadpipes are fixed or soldered onto the slide section of the instrument but some trombone models do allow for interchangeable leadpipes.

Mouthpiece: Using different mouthpieces on the same instrument effects your embouchure and therefore the sound coming out of the instrument. Before changing mouthpieces, make sure the bore of the mouthpiece matches the bore of the instrument.

Reciever: Also called the venturi, this is where you stick the mouthpiece.

Resistance: The effort it takes to make air flow through the horn. When opened, an f attachment creates more resistance due to the added length of tubing and the bends in that tubing.

Slide: the part of a trombone that the player moves back and forth to play different notes. Yeah, kind of obvious.

Spit valve: This allows you to drain condensation from out of your horn. Politer people call it the water key.

Slide lock: Stops the slide from moving when unattended.

Stockings: The ever so slightly wider ends of an inner slide.

Straight Trombone: A basic trombone without the F-attachment.

Tenor Trombone: The most common type of trombone that plays in the key of B flat. Add the F attachment and it will also play in the key of F.

Trigger: The thumb operated lever that opens and closes the valve to the F attachement.

Trigger Trombone: A tenor trombone with F-attachment operated by a trigger .

Throw: The distance the trigger must be pressed to completely open the valve.

Valve: The valve is the mechanism by which the airflow of the trombone is redirected from flowing through the straight part of the trombone to flowing through the F attachement and back into the bell

Tuning slide: F attachments ususally have an adjutable slide to adjust the pitch of the instrument. As the metal of any brass instument responds to changes in its playing environment such as external temperature, internal temperture, or even humidity, the pitch of the instrument will change.

Wrap: The tubing that makes up the F-attachment.
