Let’s dive into a trumpet!


The mouthpiece is made of metal, with a cup on one side which opens into a small tube. It is this part of the instrument that the players buzz on to produce sound. It directs airflow into the trumpet. Rim, cup, throat and backbore are all parts of the mouthpiece. This mouthpiece can be customized according to the player’s comfort.

Mouthpiece receiver

Mouthpiece receiver is in a shape of a cylinder fused at the end of the leadpipe which connects it to the trumpet.


A metal tube which extends all the way from the mouthpiece to the tuning slide is known as the leadpipe. You got to be careful while handling your trumpet so that no accidental bumps create dents in the leadpipe. A small change in the airflow can change or even destroy your trumpet’s original tone.

Valve casings, piston and slides

There are three cylindrical valve casings on a trumpet. They are positioned in the center of the instrument. The cylinders hold the valve pistons, which move up and down in the valve casings to produce different tones. Every piston is unique to its casing.

Thin metal cylinders with holes, both large and small bored through, and small fingerpieces on the end are known as the valve pistons.

There are three valve slides on a trumpet. Each slide is placed at a precise point in the way of the airflow which allows the trumpeter to change the pitch by pressing pistons while playing. A player can also make micro-adjustments in tuning of the trumpet by moving the slides in and out.


A metal hook on the top of the trumpet that allows the player to hold the instrument in one hand and use the other to play the instrument is known as the fingerhook. The horn can be played with just one hand by using the fingerhook.

Tuning slide

It is the largest slide on the trumpet. It is a C-shaped metal tube that can slide in and out to adjust the tuning of the trumpet. Further out the tuning slide, lower will be the tone that your trumpet produces.

Water key

A metal lever found on the trumpet’s main tuning slide is known as the water key. While playing a trumpet it is common that some amount of moisture gets collected in the slide. Pressing on the water key opens a small hole in the tuning slide which allows the excess moisture to escape.

The Bell

The vast area in a trumpet made of metal and the first thing that you notice when you look at a trumpet is known as the bell. It is last step in the process of making sound. The bell amplifies and shapes the sound of the instrument. They come in a wide variety of flares and sizes.

That’s all the parts that a trumpet has. Isn’t it truly a magnificent instrument? If you want to learn how to play a trumpet then make sure you go through the above information so that you can reap the maximum benefits out of your trumpet lessons.
