In 2011 while conducting experiments with sine tones by programming sound wave generation in Pascal code at the computer, one of my ventures yielded a mono wave, which instead of being rendered within – and lasting in playback – a few seconds, took to my surprise a whole hour to compute, and it lasted practically as much when played back (actually 62 minutes). The qualities of this accidental by-product fascinated me and I wholeheartedly welcomed it. Starting with a hectic songbird-like sinusoidal twittering, it very slowly transitions over its whole hour to final dissipation and decay. I entitled it Songbird’s Hour. Sometimes silences of several minutes intersperse themselves as a part of the process, the longest of these lasting as much as over 16 minutes.
