Timeline of music technology

The timeline of music technology provides the major dates in the history of electric music technologies inventions from the 1800s to the early 1900s and electronic and digital music technologies from 1874 and electric music technologies to the 2010s.

Dates

 * 1874 : Elisha Gray's Musical Telegraph
 * 1876 : Alexander Graham Bell completed his designs for the telephone. This device contributed to electric technologies that would subsequently be used in music technology)
 * 1877 : The microphone was first invented by David Edward Hughes, despite Thomas Edison being granted the patent. Hughes discovered that electrical currents varied when sound vibrations were passed through carbon packed into a confined space. His first broadcast was of scratching insects.
 * 1877 : Thomas Edison and Emile Berliner simultaneously invented the first prototypes of the phonograph
 * 1888 : Thomas Edison introduces the electric motor-driven phonograph
 * 1896 : Edwin S. Votey completes the first Pianola
 * 1898 : Valdemar Poulsen patents the Telegraphone
 * 1906 : Thaddeus Cahill introduces the Telharmonium to the public
 * 1906 : Lee De Forest invented the Triode, the first vacuum tube
 * 1910 : Utah Mormon and Nathaniel Baldwin construct the first set of headphones from an operator's headband and copper wire. Baldwin failed to commercialize the opportunity through attracting orders from private companies and even the Smithsonian Institution, though the Navy purchased hundreds of sets of them in anticipation of possible world war.
 * 1910 : Vladimir Baranoff-Rossine constructed the Piano Optophonique
 * 1912 : Major Edwin F. Armstrong is issued a patent for a regenerative circuit, making radio reception practical
 * 1915 : Lee de Forest created the Audion Piano
 * 1917 : Leon Theremin invented the prototype of the Theremin, an instrument which is played without touching it, as it detects the proximity of the hands
 * 1921 : First commercial AM radio Broadcast made by KDKA, Pittsburgh, PA
 * 1925 : The Victor Orthophonic Victrola Phonograph was invented. A far superior product in comparison to other phonograph manufacturers was an acoustic sound design that was far superior to current offerings.

 * 1927 : Pierre Toulon and Krugg Bass invent the Cellulophone
 * 1928 : René Bertrand invents the Dynaphone

The Great Depression unfortunately made the market unreceptive due to their high cost and initial marketing of these devices being as "Program Transcriptions", rather than for listening to music. Despite their existence, it was not until 1948 that Columbia Records reintroduced this format.

 * 1938 : Georges Jenny develops the Ondioline
 * 1938 : Benjamin B. Baur of Shure Bros. engineers a single microphone element to produce a cardioid pickup pattern (it picks up less sounds from the sides of the microphone, reducing unwanted sound pickup)
