TROMBONE operates under the same principles as a trombone. Real trombonists tighten or loosen their lips to select a partial -- Bb, F, the Bb above that, and so on, according to the overtone series. Then they can use the slide to change the note; the farther out they push the slide, the lower the resulting pitch. The slide lets a trombonist get at those notes between the partials.

TROMBONE, however, doesn't have a brass mouthpiece, and we don't recommend putting your lips on your iPhone, however much you might love it. Rather, you can pick how you want to simulate the mouthpiece -- by tilt, breath, or by touch.

Simply touch the slide to move it out. You'll soon find that it's tricky at first to play in tune -- that's why we included a "Snap to Slide Position" option that will put frets down on the slide. Or stay fretless to do those great glissandos.

Samples and synths.

In addition to real trombone samples, TROMBONE includes the Visual Synth. You can combine waves of various shapes to create complex and unexpected timbres. You can sculpt the overtones and see the resulting wave right before your eyes.

Apply the low-pass Filter to take the edge off and some Reverb to add a little echo. Now your TROMBONE sounds like some kind of Martian flute. Or Pac-man.

Musicians: hear, hear!

Record your performances and you can play them back, note for note, and even see the slide bounce back and forth as you played. Save your TROMBONE performances online. Listen to them online, and they sound just like they did on your iPod or iPhone.

You can hear other people's performances too, and see what kind of settings they played with. Embed your performance in your blog, send it to your grandma, or just vote it up and see if you're the world's best TROMBONE-er. (Ahem.)
