Ambient
The idea of Ambient music was born in the early 20th century with the search for music that could 'be in the background' at dinner parties. In the 1950s there was music constructed from real-world sounds. Composer Brian Eno made first used the term 'ambient music' in his 1978 release Ambient 1: Music For Airports.
Habbo/8bit
Habbo Hotel's graphical style is reminiscent of old C64 and Atari computer games. Habbo's pixel-style is very recognisable and so the Habbo sound and music has a similar retro approach. In music this means the use of limited polyphony, simple melodies, clearly synthetic instruments and 4bit or 8bit lo-fi sounds.
