No, a saxophone has keys like other woodwind instruments. Brass instruments have valves.
The saxophone is actually a member of the woodwind family because it produces sound through a reed vibrating against the mouthpiece, similar to other woodwind instruments like the clarinet. While it is made of brass, its classification is based on its method of sound production rather than its material.
A trombone has a slide, which other brass instruments lack.
The saxophone is a woodwind instrument that is actually made of brass. It uses a single reed mouthpiece to produce sound, similar to other woodwind instruments, but its body and keys are made of brass.
That depends on the music. Most often, it is played in a band, with other brass instruments, woodwind instruments, and percussion instruments. It is also played in the orchestra, with other brass instruments, woodwinds, and strings. It can be played in ensembles with other trumpets or brass instruments. Or, it can be played with piano accompaniment.
Brass instruments are primarily made of brass, which is a metal alloy of copper and zinc. They are called brass instruments because the majority of their construction is made of brass, even though some parts, like valves and slides, may be made of other materials such as steel or nickel silver.
Saxophones are a family of instruments invented by Adolphe Sax, who gave them his name. They are made of brass, like trumpets and other brass instruments, have a conical bore, like brasses and also some woodwinds, but are keyed like a woodwind and have a single reed like a clarinet. They range from high pitched soprano to low-pitched bass.
Adolphe Sax invented the saxophone, patented the entire family of saxes and actually made the first instruments. He called the instruments he made saxophones, and by the time other manufacturers could make them, that's how they were known by the public. He did the same thing with a family of brass instruments known as sax horns, which were popular in the late 1800's and are still used to some degree today.
Brass is a rust-resistant metal compound that was relatively easily and inexpensively obtained by our ancestors, polishes easily, is malleable and has interesting musical properties at various thicknesses. Brass is comparatively light-weight compared to the other metals historically available. It should be noted that in modern times saxophones have been made of other materials, namely fiberglass. These instruments do not have the same tonal qualities as brass saxophones, and so are not widely used for anything other than training.
saxophone, clarinet and other instruments you would normally hear.
Baritones and trombones are unique brass instruments due to their slide mechanism, which allows players to change the pitch smoothly and continuously. This feature sets them apart from other brass instruments that use valves to change notes. Additionally, baritones and trombones have a rich, mellow sound quality that distinguishes them from other brass instruments in the orchestra or band.
The trombone is the only instrument in the brass section with no keys or valves. It only has a slide.
