We all need a little help sometimes

Whether it’s learning to ride a bike or reaching something from a high shelf, it’s normal to need a little help as we grow and learn a new skill. The trombone isn’t any different. Learning to tame this beast of an instrument is a struggle. The smaller size of young students doesn’t need to make it harder. Just as most children grow out of using a stepstool to brush their teeth or wash their hands, most students will grow out of using Extendabone. But for those of us who still use a stepstool for the highest shelves in the kitchen, it’s a good thing Extendabone is for players of all ages!

HOW IT WORKS

Clip it on and play the way you normally do.

Extendabone provides the extra inches when you need them and gets out of the way when you don't.

Everyone can reach 6th and 7th position. Everyone can play in tune.

No one has to buy an expensive instrument before they can afford it.

Extendabone is an easy and inexpensive solution that lets everyone play trombone from day one.

Clip onto the handslide with the logo facing out. If it is too loose, attach the foam inside the clip.
It should pivot but not slide up and down.

Hold the handle just like the trombone slide. The fat part of the handle fits in your palm with a groove for your thumb.

Hold Extendabone in line with the slide handle until you need the extra length to reach far positions.

Fold it back parallel with the stockings when you don't need it.

Why a slide extension handle?

Because I am a professional trombonist who has performed all around the world, and I still need one!

Like most beginners, I could barely reach 6thposition and not reach 7that all when I started. Unlike the majority of kids, my parents were able to buy me a trombone with an F attachment, so this wasn’t really a problem until I got to Juilliard.

At Juilliard, I encountered the first piece that was impossible to play without using 7thposition, Stravinsky’s Pulcinella Suite. Despite my teacher, Joe Alessi, teaching me every possible trick, I still could not reach 7thposition enough to play in tune. Joe supposed that this was a common enough problem that there must be some kind of slide extension handle on the market.

At the time, he was right. DEG Music made this extension handle. Unfortunately, this is no longer the case. There is no slide extension handle on the market.

This seems completely unacceptable to me. I know that I am not the only player, female or male, who has a hard time reaching 7thposition. It seemed imperative that someone create a solution.

Extendabone is my solution. It is designed to be easy to use and comfortable to hold. Its shape mimics the empty space created when one holds a trombone slide properly between the thumb and first two fingers and there is a groove on the back to show beginners where to place their

thumb. I designed it to create something that not only solved the problem of short arms, but also helped encourage good technique when not using extendabone.

Extendabone is an inexpensive product that lets every player at any age play trombone to the best of their abilities.A further benefit is that students can no longer pick up their middle finger to touch the bell when playing in third position, so it has extra pedagogical fringe benefits!
