Pañc hazar chakra kai andar (2000)5:42
Pañc hazar chakra kai andar or Within Five Thousand Cycles is a piece for Yamaha Disklavier that attempts to explore the instrument within the context of John Cage inspired piano preparations (utilizing machine screws, flat mudguard and standard washers, plastic and brass olives, paper clips, cup head bolts, hex full nuts, white board and fold back clips), North Indian ‘Hindustani’ derived cyclic rhythmic patterns (juxtaposing two contrasting talas: Jhumra, 14/4 or 3 + 4 + 3 + 4 and Champak sawari, Champak sawari, 11/4 or 4 + 4 + 1 1/2 + 1 1/2), analogue synthesis (including Arp 2600 LFO/Sine Wave filter sweeps, envelope filtering and Mu-tron Bi-Phasing), digital effects processing (ring modulation, distortion, 4-band eq, chorus, reverb, delay), studio generated harmonic resonance or ‘sympathetic vibrations’ and modern digital hard-disk recording technology.
To achieve the LFO/Sine Wave filter sweeps, the natural recorded signal was routed through an Arp 2600 Monophonic Analogue Modular Synthesizer (patching: preamplifier output to voltage controlled oscillator VCO-2; voltage controlled oscillator VCO-2: low frequency oscillator= keyboard off, initial oscillator frequency= ≤ position between .03Hz and .3Hz; voltage controlled filter/resonator VCF: initial filter frequency= π position between 1KHz and 10KHz, VCO 2/sine Wave= 5.625)
To achieve harmonic resonance or “sympathetic vibrations”, the following equipment was utilized: Allen & Heath Saber 48 x 16 x 2 mixing console, Tascam M-208 8 x 4 x 2 mixing console, Optro Dual Monitor 109 ‘50 watts RMS’ power amplifier, Electro-Voice SH-150ER ‘200 watts’ speaker (2-way horn loaded stage system). The Electro-Voice speaker was placed underneath the Disklavier at least 200mm off the ground; the speaker fed the natural recorded signal via the Allen & Heath Saber Mixing Console’s auxiliaries, utilizing the other mixing console and amplifier as a power source; the sustain pedal on the Disklavier depressed with the resulting harmonic resonance recorded.
