The Wagner tuba is a narrow-bore tuba with a French-horn mouthpiece. Tubas appeared first in Berlin in the 1820s, soon after the invention of the valve. They were soon accepted into the band and orchestra, displacing the serpent, ophicleide, and other such instruments of poorer tone quality and intonation.
Microphone were used with the first telephones, and then with radio transmitters soon after. Sir Charles Wheatstone was the first person to come up with the word âmicrophoneâ in 1827, but even so, it was Emile Berliner who invented the first microphone in 1876. Emile Berliner was born in Hanover, Germany in 1951. When he was 19, he moved to the United States in Washington.
