Slide trumpet

The slide trumpet is a member of the brass (Hornbostel–Sachs 423.22). Learn how it makes its sound and explore related instruments.

How the slide trumpet makes its sound

In the Hornbostel–Sachs system, which classifies instruments by how they produce sound, the slide trumpet belongs to the brass (lip-vibrated aerophones): the player's buzzing lips set the air column vibrating – trumpets, horns, trombones, tubas and the didgeridoo.

More broadly it is one of the aerophones (wind instruments), where sound comes from vibrating air.

Press play above and watch the spectrum: the evenly spaced peaks are harmonics, and their relative strength is what gives the instrument its character.

From Wikipedia

The slide trumpet is an early type of trumpet fitted with a movable section of telescopic tubing, similar to the slide of a trombone. Eventually, the slide trumpet evolved into the sackbut, which evolved into the modern-day trombone. The key difference between these two instruments is that the slide trumpet possesses only a single slide joint, rather than the two joints in the U-shaped slide of the sackbut or trombone. There are several types of slide trumpet of different places and eras.
