The tuba is the largest and lowest pitched of brass instruments. Sound is produced by vibrating or "buzzing" the lips into a large cupped mouthpiece. It is one of the most recent additions to the modern symphony orchestra, first appearing in the mid-19th century when it largely replaced the ophicleide.
The euphonium is a conical-bore, baritone-voiced brass instrument. It derives its name from the Greek word euphonos, meaning "beautiful-sounding" or "sweet-voiced" (eu means "well" or "good" and phonium means "voice"). The euphonium is a valved instrument; nearly all current models are piston valved, though rotary-valved models do exist.
