Music technology is the study or the use of any device, mechanism, machine or tool by a musician or composer to make or perform music; to compose, notate, playback or record songs or pieces; or to analyze or edit music. The earliest known applications of technology to music was prehistoric peoples' use of a tool to hand-drill holes in bones to make simple flutes. Ancient Egyptians developed stringed instruments, such as harps, lyres and lutes, which required making thin strings and some type of peg system for adjusting the pitch of the strings. Ancient Egyptians also used wind instruments such as double clarinets and percussion instruments such as cymbals. In Ancient Greece, instruments included the double-reed aulos and the lyre. Numerous instruments are referred to in the Bible, including the cornu, pipe, lyre, harp, and bagpipe. During Biblical times, the cornu, flute, horn, pipe organ, pipe, and trumpet were also used. During the Middle Ages, music notation was used to create a written record of the notes of plainchant melodies. During the Renaissance music era (c. 1400-1600), the printing press was invented, allowing for sheet music to be mass-produced (previously having been hand-copied). This helped to spread musical styles more quickly and across a larger area. During the Baroque era (c. 1600–1750), technologies for keyboard instruments developed, which led to improvements in the designs of pipe organs and the harpsichord, and the development of a new keyboard instrument in approximately 1700, the piano. In the Classical era, Beethoven added new instruments to the orchestra such as the piccolo, contrabassoon, trombones, and untuned percussion in his Ninth Symphony. During the Romantic music era (c. 1810–1900), one of the key ways that new compositions became known to the public was by the sales of sheet music, which amateur music lovers would perform at home on their piano or other instruments. In the 19th century, new instruments such as saxophones, euphoniums, Wagner tubas, and cornets were added to the orchestra.
