Tides is an electro-acoustic composition for piano, laptop and quadraphonic speaker system. This work was trying to combine a scored instrumental part with laptop processing in real-time. I wanted to emphasise parts of the piano sound that I find enjoyable. The gradual decay of chords, dense clusters of sustained tones, the fading of vibrations to near-silence, the low frequencies of the piano and using harmonically vague progressions via adding and subtracting tones. The computer part involves a 4 head tape delay module, circular spatialisation, sine tone generation based on pitches the computer hears. Also very important to this piece is the amplification, diffusion and compression of the piano – enhancing the sound of the acoustic instrument is critical to hearing the level of detail that I was trying to achieve.
As with most of my works, the score is still in a rough state, but I have a recording from mid-2009 that reasonably captures most of the work. Piano by Ben Hamblin, live laptop by Kynan Tan.
