The original "Drumming-by-Dancing" (a.k.a. non-tactile "air drums") mode after which Drancing was named. Drum samples are triggered by conditioned triaxial accelerometer signals driven by free body movement.

The (X,Y,Z) channels of five 3D accelerometers vary the amplitudes of notes of fixed (C,E,G) chords at different octaves. When the amplitude varies by small amounts about a larger mean value (such as when waving the arms about a common raised level) the mode can be said to represent Amplitude Modulation (AM).

This is a subtle mode, and care must be taken to sufficiently distinguish the notes of each chord triad. Amplitude variation can also be well combined with other modes such as variation of the frequency of oscillators.

Demonstrates variable frequency oscillators + triggered drum samples ("Drumming by Dancing", "air drums") modes along with Drancel RGB monitor visuals projected onto the "Drancer" performer.

For this demonstration two hand-held WiiTM Remotes on a MacBook Pro were used.

The (X,Y,Z) channels of five 3D accelerometers vary the amplitudes and the frequencies of 5 x 3 = 15 pure sinusoidal oscillators.

One can hear "beat" frequencies generated by similar frequencies corresponding to different accelerometer channels, such as when the arms are raised to similar levels, which effect can be exploited for musical nuance and for movement therapy to measure symmetry of posture.

Demonstrates 2 "Drancer" acceleration avatars, each with 5 Drancel RGB triaxial accelerometer synthesis atoms, with orthogonal "light cones" (which correspond to LEDs with reflectors). The sound here is synthesised from 2 sets of WiiTM Remote accelerometer signals driving Variable Frequency Oscillators (VFOs) in Pure Data; the visuals are in GEM. (For this demonstration every Drancel RGB of each Drancer receives the same signals.)

A minimal example of Drancel RGB 2D visuals. The colour of the central circle is an average over the RGB colours corresponding to the XYZ axes of a triaxial accelerometer. Driven by a WiiTM Remote as wireless accelerometer signal source.

Demonstrates one Drancel RGB accelerometer synthesis atom design, with orthogonal "light cones" (which can correspond to LEDs with reflectors). The sound here is synthesised from simulated sinusoidal accelerometer signals driving Variable Frequency Oscillators (VFOs) in Pure Data; the visuals are in GEM.

Demonstrates two "Drancers" (acceleration avatars of the Drancing accelerometer music system) with 5 Drancel RGB accelerometer synthesis atoms (corresponding to hands/wrists, feet/ankles, and waist). The sound here is synthesised from simulated sinusoidal accelerometer signals driving Variable Frequency Oscillators (VFOs) in Pure Data; the visuals are in GEM.
