A chiptune, or chip music, is music written in sound formats where all the sounds are synthesized in realtime by a computer or video game console sound chip, instead of using sample-based synthesis. The "golden age" of chiptunes was the mid 1980s to early 1990s, when such sound chips were the most common method for creating music on computers.
Early computer sound chips had only simple tone and noise generators with few channels, imposing limitations on both the complexity of the sounds they could produce and the number of notes that could be played at once.
In their desire to create a more complex arrangement than what the medium apparently allowed, composers developed creative approaches when developing their own electronic sounds and scores, employing a diversity of both methods of sound synthesis, such as pulse width modulation and wavetable synthesis, and compositional techniques, such as a liberal use of arpeggiation. The resultant chiptunes sometimes seem harsh or squeaky to the unaccustomed listener.
