As you can imagine, the limited range of motion allows you to press and release the trigger quickly. If you’re doing everything correctly, your trigger should barely move. After all, I’d hate for you to break a string or bust a rotary valve. Notice the full range of motion of the trigger, and be careful not to push beyond that range. With your hands in place, take a moment to squeeze the trigger a few times with your thumb. If you’re not totally comfortable with some of this terminology, check out my article on trombone anatomy. Of course, the only difference here is that your thumb will go on the trigger instead of over the bell brace. First, grab your horn like you normally would with one hand on the slide brace and another hand on the slide. Now that we know what we’re looking at, let’s talk about how to use an F trigger. Otherwise, you have a closed wrap horn which is more compact. If you have an open wrap, you’ll notice that the tubing sticks out beyond the limits of a straight trombone. In particular, there are two different types of wraps, open and closed, which refers to the amount of additional tubing that sticks out from the bell. In general, the rotary valve is the most common, but there are plenty of options including axial flow and dual bore.įinally, the valve feeds into the wrap which is the additional tubing not found on a straight trombone. On the other end of the linkage, you’ll find the valve which is the mechanism which changes where air flows in the trombone. Meanwhile, the mechanical linkage functions largely the same way, but the string is replaced with a metallic arm. When the trigger is pressed, the valve will rotate into place. With a string linkage, you’ll notice a string that’s attached to the trigger and wraps around the valve. In general, there are two types of linkages: string and mechanical. Then, the linkage is the mechanism which connects the trigger to the valve. Unlike a straight trombone, your thumb won’t go over the bell brace which may feel a little odd at first. As a result, when you wrap your hand around the the slide brace, your thumb will rest right on top of the trigger. Typically, the trigger is a piece of metal that sits along the bell brace closest to the bell. If you take a look at your horn right now, you’ll notice that the F trigger is made up of four main sections: the trigger, the linkage, the valve, and the wrap. In the remainder of this article, we’ll take a look at the anatomy of a trigger, how to hold a horn with a trigger, the benefits of having a trigger, and how to maintain a trigger. Finally, it opens up the possibility for trills. In addition, it adds new options for positions like middle C in 1st position rather than 4th. As a result, you can access an extended range which includes false tones and pedal tones. First, it drops the pitch of a tenor trombone by a perfect fourth. In general, the F trigger on a trombone provides three uses. As a result, I decided to do some research and put together a guide on how to use a trombone F trigger. From my best understanding, an F trigger drops the pitch 5 half steps, but that was about all I knew. As someone who has never owned a trigger trombone, I’ve always been very interested in how they work.
