Historical+Evolution

How did Electronic Music evolve? water to operate, air pressure inside, not electric, had principles of power, all different size types, different pitches (like blowing on a bottle), sounds like an organ, invented 2nd century
 * The Hydraulis:**

could create different pitches, electromagnets, over telephone lines
 * Elisha Gray and "The Musical Telegraph" (1876):**

Thadeus Cahill, telephone receiver attached to a horn, first type of cable broadcasting, original idea of playing music of telephone wires, Cahill envisioned broadcasting music with an actual electric instrument, would sound ok over phones, 14,000 pounds, Cahill began to look for money to build a bigger one, constructed and hired musicians to play it, resemble instruments of the orchestra, something like an organ, but could resemble instruments, 200 tons, 200,000 dollars to build, 14,000 watt generator to play music, moved to Broadway, New York, most complicated instrument of all time, two people play, bass player and melody / treble
 * Telharmonium:**

generated sounds and projected revolving patterns onto a wall or ceiling (similar to windows media visuals)
 * The Optophonic Piano (1916):**

Leon Theremin, invented 1919, two poles, one controls pitch, one controls dynamic,
 * Theremin:**

Clara Rockmore - important figure in electronic music

Keyboard instrument based on the theremin, rhythmic content created by rotated disks, interrupts light beams, photoelectronic cells, vacuum tubes oscillators for pitch, 17 keys
 * Rhythmicon or "Polyhythmophone" (1930)**:

first successful electronic instrument, used in orchestras, controlled by a sensor slider, often attached to a piano, fixed positions for notes, touch sensitive for vibrato
 * Ondes-Martenot (1928):**

Used to record on magnetic tape. Schaoffer chose to name his new art musique concrete to differentiate, cut pieces of magnetic tape, stuck back together
 * Musique Concrete (1930's):**

First sort of electronic one may put in their own house, the way people could start making their own electronic music
 * Hammond B-3 Organ:**

cost $500,000, punches paper rolls to program the machine and make the music
 * RCA Mark 2 (1950's):**

many modules patched together to make infinitely many different types of sounds
 * Moog Modular Synthesis (1967):**

ASDR: attack, sustain, decay, release

after this synthesizer, Moog worked to make it smaller and smaller, until the "Mini Moog"

Voltage control oscillator, pitch Voltage control amplifier, dynamics Low frequency oscillator, rhythm essentially

** Synthesizer invented by David Van, among the first widely available, portable, and affordable synthesizers, monophonic (could only play one not at a time)
 * Mini Moog (1970):

preset, polyphonic synthesizer, very very portable
 * Polymoog (1975):**

Real revolution in digital synthesizers, first reasonably priced synth on the market
 * Yamaha DX7 (1983):**
