Although the tones featured in NES music can be thought of as emulating a traditional four-piece rock band (triangle wave used as a bass, two pulse waves analogous to two guitars, and a white noise channel used for drums), composers would often go out of their way to compose complex and rapid sequences of notes, in part due to the restrictions mentioned above. This is similar to music composition during the Baroque period, when composers, particularly when creating solo pieces, focused on musical embellishments to compensate for instruments such as the harpsichord that do not allow for expressive dynamics. For the same reason, many early compositions also feature a distinct jazz influence. These would overlap with later influences from heavy metal and J-pop music, resulting in an equally distinct compositional style in the 16-bit era.
