The concept of this instrument is purely based on the Ektar<\/em> or the Ektara; Ektar\u00a0<\/em>literally means “one-string”. The Ektar was created in India and was traditionally made out of a gourd and some bamboo. It is played by plucking the string and simply bending the two pieces of bamboo. When bending the bamboo you lessen the tension of the string thus lowering the pitch.<\/p>\n

In my most current iteration (prototype 6) of the modern Ektar I laser cut red acrylic in place of the bamboo and wood in place of the gourd. The laser cut design is all done in Rhino. Using a piezo mic to pick up the sound from the resonator, I route the sound to an iMic USB interface which is then connected to a USB hub. The other component connected to the hub is a teensy that is collecting data from a gyroscope. The Teensy 2.0 is programmed in Arduino to translate the gyroscope data into midi data. The x \u00a0and y data from the gyroscope is then sent to MaxMSP and is displayed through an object called Nodes. The nodes object creates a venn diagram comprised of four circles. Circles one and four contain yafr~, a third party reverb engine that excretes a very boomy sound for circle one and a dryer sound for circle four. Circles two and three contain a feedback engine using poly~; circle two is down an octave and circle three is up the octave. By tilting the Ektar front, back, left, and right you can travel through the different circles and there sound fields. With a simple flick of a switch you can turn the processing on\/off making it playable as both an acoustic and hybrid instrument.<\/p>\n

Prototype No.1\/2:<\/p>\n

Materials: Tibetan Singing Bowl, Low E Bass String, tuning peg, 1′ x 1.5′ x 2′ block of wood, thin\/flexible wood, 3 x 1.5″ screws, 3 x nuts, 2 x 12″ metal couplers.<\/p>\n

Prototype 1 did not contain the outer wooden ring. The two rings were added in Prototype 2 so that the beams could have a flat surface to clasp on to. The rings and beams were designed using Rhino.<\/p>\n

Prototype 3:<\/p>\n

Materials:\u00a0.1875″ thick wood,\u00a0Viola C string, tuning peg, 1″ x 1.5″ x 2″ block of wood, thin\/flexible wood, 2 x 1.5″ screws, 4 x .25″ screws, 6 x nuts.<\/p>\n

Prototype 3 lacked volume. The base is a 4″ x 4″ x 4″ cube that didn’t resonate enough. Next iteration (prototype 4) the base is 5″ x 5″ x 5″ which significantly increases volume.<\/p>\n

Prototype 4:<\/p>\n

Materials:\u00a0.1875″ thick wood,\u00a0Viola C string, tuning peg, 1″ x 1.5″ x 2″ block of wood, thin\/flexible wood, 2 x 1.5″ screws, 4 x .25″ screws, 6 x nuts.<\/p>\n

Prototype 4 piezo mic and preamp is too large; it also doesn’t pick up enough signal from the resonator.<\/p>\n
