Tremolo picking is a continuous run of fluctuating downward and upward guitar picking strokes at a high speed over a single note. The picking gives off a very fast and hollow guitar sound. It was used most famously by surf musicians, like Dick Dale, The Ventures, and The Surfaris. A perfect example of tremolo picking is on the song “Wipeout”. Other genres of music, including death metal, would experiment with tremolo picking over the years, but none did it more perfectly than black metal. The technique allows for extremely fast guitar play with hollow sounds that add perfectly to the extremely creepy atmosphere and shrieked vocals.
