This means that you can change the note without moving the slide mechanism simply by using this trigger. The trigger can either activate or deactivate the extra tubing, giving the player a wider range of notes to play. In other words, the F attachment is a trigger that allows the horn to play lower notes.

Invented in the 1800s, this trigger attachment originated in Germany and the horn includes additional tubing that is activated by the trigger.

The tenor trombone is also called a trigger-type trombone when it has an F attachment because there is a trigger attachment that allows them to play in the key of F and even lower whenever necessary. This type of trombone is also good for beginning musicians because it is an inexpensive instrument that is very easy to learn. In addition, some of the more expensive tenor trombones have an F attachment, which means that they can play extra notes that other tenor trombones cannot play. It is played when a slide is pulled in and out and although most trombones are played with bass-clef notes, some can play treble-clef music. The horn becomes longer as you play it and the tuning changes from Bb to F. It is also called an F-rotor trombone and has extra tubing within the first, or main, loop. This type of trombone is the simplest type of trombone and the one that most people think of when they think of the word “trombone.” It is a basic type of trombone that has no tubing on the inside of the main section.
