F Attachment Trombone Explained: Best 11 Horns Reviewed With Video And Prices
Did you know that an F attachment trombone (with a trigger mechanism) has an extra 3 feet of tubing than a straight tenor trombone?
When you press the trigger (the “thumb paddle”), it drops your pitch by a perfect 1/4 — from B♭ (their fundamental pitch) to A, G, and F. Plus, it gives you new shortcuts — “alternate positions.”
I’ve seen many students (especially in my retail days) get super excited about their first F attachment trombone. It’s like upgrading from a regular car to one with a TURBO boost! You can still play it like a tenor straight trombone (with the trigger not pressed), but now you have extra options.
Pro tip: If you’re into jazz or orchestral music, this feature is a must-have. It’s also great for marching bands, though it is a bit heavier.
What Is F Attachment Trombone
An F attachment trombone (or “trigger bone”) is a trombone with an extra loop of tubing.
The “F attachment” loop lets players access lower notes slide positions. It is controlled by a trigger (usually near your left thumb).
The main parts include the trigger, linkage, valve, and wrap. Depressing the thumb trigger sends air through about 3 feet (10 – 15 cm) of extra tubing.
You can reach middle C and low F in the first position (a real stretch with a straight horn). Some advanced players even use it for fancy trills.
The F attachment gives you more range (especially in the lower register). It also helps intonation (playing in tune) and makes tricky slide positions easier!!
“F attachment is a lifesaver for low notes—no more awkward stretches!”
The modern F attachment designs (“open wrap”) have even more bends. Some say it is less resistance when you play (for more consistent sound). Sure, it’s a bit heavier (about 1-2 pounds more), but the benefits could be worth it.
F Attachment Trombone vs. Straight Trombone
A traditional trombone (what most beginners start with) has a simpler design. It’s lighter and easier to maintain (which most students appreciate). The traditional model only goes down to low E — fine for most basic repertoire.
The F attachment trombone (my favorite for advanced playing) offers more possibilities. Press the trigger (clicking it like a pen), drop the pitch by a perfect fourth, and hit those super low (orchestral) notes.
Play middle C in the 1st position with the F trigger instead of reaching 6th.
For beginners, don’t stress about the extra complexity. You can ignore the F attachment at first — the trigger won’t get in your way while you’re learning the basics.
