A single bar from "Fugue No.17 in A flat", BWV 862, displaying contrapuntal polyphony. The piece is part of J. S. Bach's Das wohltemperirte Clavier, Part I. See: File:BachFugueBar.png
I take out a keychain from my pocket and open the lock at the entrance door to the flat. You can hear the key ringing and the sound of the lock being opened. You can hear the sound of hitting metal on metal. Recorded using zoom h2n.
Two measures of squelchy acid bass with piercing synth chords. Created in lmms, further effects applied in audacity with valhalla supermassive. 140 bpm, a flat hungarian minor.
