DRAWDIO drawing music!

What is Drawdio? Imagine you could draw musical instruments on normal paper with any pencil (cheap circuit thumb-tacked on) and then play them with your finger. The Drawdio circuit-craft lets you MacGuyver your everyday objects into musical instruments: paintbrushes, macaroni, trees, grandpa, even the kitchen sink... higher quality video:Stream on Vimeo -- drawdio.mp4 -- drawdio.wmvMade with Paula Aguilera and Eric Rosenbaum. Thanks to Matea, Micah, Will, Chris G., and Jodi. Drawdio brings to life the everyday interconnections between people and environment, encouraging you to use your sense of touch, and letting you hear otherwise invisible electrical connections by creating, remixing, and playing. How Can I Participate? How Was It Invented? I like showing how ideas germinate. Drawdio - Make It . By Jay Silver .

Calibrated Background Noise Generators | Online & Free aM laboratory Infinite String Quartet CMoy Pocket Amplifier Common Cmoy Cmoy in parts A CMoy is a pocket headphone amplifier originally designed by Chu Moy on the headwize.com Headphone Resource Site and public discussion Forums. The headphone amplifier is designed around single or dual-channel op-amps such as Burr-Brown's OPA2134 or OPA2132PA, however, a wide variety of op-amps have been successfully implemented. Circuit[edit] A typical CMoy consists of two identical AC coupled, non-inverting operational amplifier circuits each with a 100kΩ input impedance. Power is supplied to the opamps using a dual power supply, which effectively divides the input voltage source in half to create a virtual ground. References[edit] External links[edit]

Microtonal music Composer Charles Ives chose the chord above as a good candidate for a "fundamental" chord in the quarter tone scale, akin not to the tonic but to the major chord of traditional tonality.(Boatright 1971, 8-9) Play or play Terminology[edit] Many microtonal equal divisions of the octave have been proposed, usually (but not always) in order to achieve approximation to the intervals of just intonation. Terminology other than "microtonal" is used by theorists and composers. History[edit] Greek Dorian mode (enharmonic genus) on E, divided into two tetrachords. Play Guillaume Costeley's "Chromatic Chanson", "Seigneur Dieu ta pitié" of 1558 used 1/3 comma meantone and explored the full compass of 19 pitches in the octave. The Italian Renaissance composer and theorist Nicola Vicentino (1511–1576) worked with microtonal intervals and built a keyboard with 36 keys to the octave known as the archicembalo.
