The tuba is the largest and lowest pitched brass instrument. 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. Tuba is Latin for trumpet or horn. The horn referred to would most likely resemble what is known as a Baroque trumpet. Prussian Patent No. 19 was granted to Wilhelm Friedrich Wieprecht and Carl Moritz on September 12, 1835 for a "basstuba" in F1. The original Wieprecht and Moritz instrument used five valves of the Berlinerpumpen type that were the forerunners of the modern rotary valve. The addition of valves made it possible to play low in the harmonic series of the instrument and still have a complete selection of notes. Prior to the invention of valves, brass instruments were limited to notes in the harmonic series, and were thus generally played very high with respect to their fundamental pitch. Harmonics starting three octaves above the fundamental pitch are about a whole step apart, making a useful variety of notes possible. The ophicleide used a cup-shaped brass instrument
