The

CANON

is a compositional technique for creating musical harmony by

repetition of similar melody with time delay. In this installation, the canon is reinterpreted as an emergent kinetic musical instrument. It consists of six layered kinetic sculpture making rhythmical percussion sound by its own motion. The motion of each kinetic sculpture is triggered by the present position of body walking through space over time. In this way, it generates overlayed emergent percussion sound and motion with interval depending on overlapping the present and the past of body in space.

First Idea: A mix media interactive installation


Second Idea: A Kinetic Sculpture interacted with hand gesture

Emergent Pattern Making We made a series of emergent pattern.

Structure Making Fix the laser cut pieces on a axiel shaft to make a flexible and rotateble emergent pattern. The pattern part will be fixed on servo by wood cross.

We use 1.5 meter length timber wood bar and 15 mm thickness timber wood board made a stand structure to hold the rotation part. The base of this wood stand is designed in trangle fixator to extenuate the viberation from sevor. Audience could obeserve the rotation it in a parallel eyesight and influence rotaion angles by apporaching this installation.


Simulation

We use Kinect as our motion sensing input device which could collect 3D data and recognise participant’s position and gesture. In this project, we use it as the imput device to collect participant’s motio data, especially their hand gesture and postion. When participant lift his hand and walking close to the installation, each layer’s pattern will rotate as same angle with his hand. Then, the rotation will spread cross layers with the time go on .

Third Idea: A Kinetic Emergent Sound Machine Cog Design

According to the feedback from audience, each layer’s pattern is too compilcated and abstract their attention. Another problem is the scale of installation is too large. To solve these problem, we change each layer to a more simple shape and use cog to transfer movement from servor to pattern part. Then, the pattern part could show a clear full view without shelter of servo. To present the idea of melody Canon, we add each layer with a shade inside which enclosed several marbles. With the rotation of shade, marbles will pronounce click sound with rhythem.

Table-stand Structure To provide a more stable support and save more cost, we build a table-stand structure to hold each layer of installation.


Assembly

All the wood and archlic components are cut by laer cutting macine. Most parts are connected by screws and

wood glue to make them stable. However, the core part, which include motor hoseing and cog’s joints use mor-

• Use wood glue stick many layers of wood pairs into a couple

tise and tenon joints to connect, which come from chinese’s Sunmao structre. It could the wood pieces stable and felxible during the useage, also, give us a chance to adjust each installation’s starting angles sligtly during the show.

structure. • Fix M2 screw servo’s cross on wood component. • Use 1.5mm drill bits prescrew holes on pairs. • Use M2 screw fix servo with motor house. • Fix motor house on arclic strcture with M3.5 wood screw.

Driving Cog & Driven Cog • M4 screws and bolts were use to fix sperate cogs and arclic pannel. • Fix the upper part on structure with M12 screwed bar and bolts,

Table-stand Structure • Screwed M12 steel is used to fix at the shafr position with bolt. • M6 screwed steel was cutted in B-made to keep a fixed distance between two arlic pannel.
