Question: Information:  - The ophicleide is a keyed brass instrument similar to the tuba. It is a conical-bore keyed instrument belonging to the bugle family and has a similar shape to the sudrophone.  - Brass is a metal alloy made of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.  - The subcontrabass tuba is an extension of the tuba family within the modern contrabass tuba . At least five known examples have been created , all pitched in BBBb , sounding a full octave lower than standard BBb contrabass tubas . Music for them is written in bass clef sounding a full octave lower than notated .  - The tuba is the largest and lowest-pitched musical instrument in the brass family. Like all brass instruments, sound is produced by moving air past the lips, causing them to vibrate or "buzz" into a large cupped mouthpiece. It first appeared in the mid 19th-century, making it one of the newer instruments in the modern orchestra and concert band. The tuba largely replaced the ophicleide. "Tuba" is Latin for 'trumpet'.  - A trumpet is a musical instrument commonly used in classical and jazz ensembles. The trumpet group contains the instruments with the highest register in the brass family. Trumpet-like instruments have historically been used as signaling devices in battle or hunting, with examples dating back to at least 1500 BC; they began to be used as musical instruments only in the late-14th or early 15th century. Trumpets are used in art music styles, for instance in orchestras, concert bands, and jazz ensembles, as well as in popular music. They are played by blowing air through almost-closed lips (called the player's embouchure), producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century they have primarily been constructed of brass tubing, usually bent twice into a rounded rectangular shape.   - Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets.  - A concert band, also called wind ensemble, symphonic band, wind symphony, wind orchestra, wind band, symphonic winds, symphony band, or symphonic wind ensemble, is a performing ensemble consisting of members of the woodwind, brass, and percussion families of instruments, along with the double bass.  - An orchestra is a large instrumental ensemble typical of classical music, which features string instruments such as violin, viola, cello and double bass, as well as brass, woodwinds, and percussion instruments, grouped in sections. Other instruments such as the piano and celesta may sometimes appear in a fifth keyboard section or may stand alone, as may the concert harp and, for performances of some modern compositions, electronic instruments.
