The mechanical noise and signature "chord" associated with the "mac mini (2010 model)" upon startup/boot. Brief mechanical motor and clicking noises followed by the famed sustained f sharp major chord (detuned 30 cents flat) being projected over low quality, built-in speakers. Mechanical noise has defined pitch and is predominantly in the mid-high frequencies. Recorded on zoom h2n, in small, empty room. Audio clip normalized in post-processing.
