What’s the Difference Between Alto, Tenor and Bass Trombones?

Trombones are one of the more interesting and unique instruments that you’ll see anywhere. Unlike saxophones, pianos, guitars or virtually any other musical instrument, trombones have no reeds, keys or strings. With trombones, it’s all about moving their long slides.

That said, like trumpets, cornets and other brass instruments, the sound that trombones make is largely dependent upon the intricate tubing that comprises the horn. Also significant to the instrument’s sound is its bell size and the shape of its bore (interior chamber). In this article, we’ll explore the things that differentiate the three most popular types of trombones: alto, tenor and bass. But before we do, let’s talk about some of their history and commonalities.
