The Trumpet is the highest voice in the Brass family. Within the Trumpet family there's the Cornet, Flugelhorn and several specialty instruments such as "C" trumpets and Piccolo trumpets (Mainly used in symphony orchestras and chamber ensembles.) For students, the most common is the Bb (B-flat) Trumpet. This is the horn that is most commonly used for jazz, concert and marching bands.

Types Student
These trumpets are machine made and built for economy and durability. They play well, but don't have all the high-end features and craftsmanship found on intermediate and professional models. Most student horns are made with a two-piece bell as opposed to a one-piece. While this affects sound and projection, it also makes for a more affordable instrument. A student horn should fit the bill for most players for the first 2 to 3 years.
Intermediate
After 2 to 3 years, a player should consider moving up to an intermediate level trumpet. There are 2 different types of intermediate horns:
Student horns with added features such as 1st valve slide/thumb hook, deluxe cases, silver plating and adjustable 3rd valve slide stops. These features improve durability and tuning.
Intermediate horns based on comparable Professional horns built with less expensive manufacturing techniques that affect resonance, looks and intonation.
Pro
These are high-end instruments made with the finest materials and craftsmanship. Features such as one-piece bell, stainless steel pistons and heavy or lightweight versions are features usually found on pro horns. A professional trumpet is worth the investment for a long-term player of any age.
