Each unit would likely be close to 1 cm in length. Notice that by the time we get down to 12 th position, the distance between positions has almost doubled!įor this table, I have assumed the distance between 1 st and 2 nd position to be 10 units for simplicity. This chart shows the length of each successive slide position increasing by 6%. If we think of the slide positions continuing on from 7 th position by utilizing triggers, we can make the instrument long enough to play a low B♮ in what is essentially 12 th position. As your trombone extends, positions drift farther apart by 6% for each position. The gap between the 2nd and 3rd positions is 6% wider than that between the 1st and 2nd positions, and this pattern continues. Let’s get started… The Physics of Slide Positions for Double Trigger TrombonesĪ fundamental concept is that to produce a note one semitone lower, the length of the instrument must increase by 6%. In this article, we will go more in depth. Our article THE TROMBONE TRIGGER MAKES IT LONGER discusses the mechanics behind slide length adjustments using triggers. Cracking the Code: Two Solutions for PrecisionĮmbrace Technology with Electronic Tuners: Using an electronic tuner can help guide you to the correct slide positions with any trigger combination.ĭelving into Mechanics: For those who relish understanding the “why” behind things, this method is for you. So, 2nd position, for example, will vary depending on whether one, two, or no triggers are being pressed.

But activate both triggers, and the positions stretch further apart than they do with only one trigger engaged. Pressing a single trigger elongates the slide positions compared to playing without any triggers. Greetings to all trombonists exploring the realm of double trigger instruments! If you’ve been on the hunt for a slide position chart tailored to these bass trombones, in this guide, we’ll delve into why a standard chart might not be the ultimate solution you’re hoping for, and we’ll uncover methods to discover slide positions for double trigger trombones.
