Best Trombone Cases – Find the Right One For You

Trombone Cases

Before we take a look at the best trombone cases, we need to cover a few trombone basics, because without knowing what kind of trombone you have, you may not end up choosing the right case to accompany it.

I only know this because of the crazy amount of reviews of people talking about one fundamental problem with their new case; “it didn’t fit their instrument”. I don’t want you to make that mistake, so let’s keep going.

The trombone is a large brass wind instrument, with straight tubing in three sections, ending in a bell over the player's left shoulder and different notes are made using a forward-pointing extendable slide. The trombone fills the range between the trumpet and tuba. In fact, the name “trombone” translates from Italian as “large trumpet.”

The Anatomy of a Trombone

Trombones come in different shapes and sizes. Variations on the tube’s diameter, length, and air pressure allow the trombone to create a wide range of sounds. The major components of the trombone to consider before purchasing are the bell type (giant horn) and the bore style (the size of the inner tube of the slide). Some trombones also include a piece of specialized hardware call an F-attachment. Trombone bells are a major part of the look and sound of this instrument.

Now, let’s match up the kind of trombone you have, so that we can find you the right case.

Types of Trombones

The three most common types of trombone are:

1. Straight tenor

2. Trigger-type tenor (also referred to as F-rotor or F-attachment)

3. Bass trombones

Other kinds include:

1. Alto trombones

2. Soprano trombones

3. Marching trombones

These varieties are less common trombone types, but are still used. So, now let’s cover the three most popular of trombones, plus alto.

Tenor Trombones

The straight tenor trombone is the simplest design, with no tubing inside the main section. The trigger type tenor, or F-rotor trombone has extra tubing within the main loop. It's a straight trombone and the tubing is activated by a trigger. This makes the horn longer, changing its tuning from Bb to F.

Bass Trombones

The bass trombone has a large bell, while retaining the same length as the tenor trombone. It is a larger bore (slide tube diameter) version of the F-rotor trombone that adds a second rotor to extend a deeper sound.

Alto Trombones

Today, the alto trombone has a smaller design and is found primarily in an orchestral setting, often used for a solo, and is pitched higher than the tenor trombone.

FUN FACT! Did you know that the first concerto for the alto trombone was written in 1756, by Leopold Mozart, father to Wolfgang Amadeus Mozart?

A wise man once said, “If you take care for your weapon, it will take care of you.”  Now to a non-musically inclined person, an instrument may not seem like much of a weapon, but to a musician... it is a sword that pierces the very core of a human’s body, mind and spirit. It divides the emotions, conquers the mind, and erases time. So make sure you get the best case you can afford in order to protect and enjoy your trombone for many years to come!
