ドラムンベース
Drum and bass is usually between 160 and 180 BPM, in contrast to other breakbeat-based dance styles such as nu skool breaks, which maintain a slower pace at around 130–140 BPM. A general upward trend in tempo has been observed during the evolution of drum and bass. The earliest forms of drum and bass clocked in at around 130 bpm in 1990/1991, speeding up to around 155–165 BPM by 1993. Since around 1996, drum and bass tempos have predominantly stayed in the 170–180 range. Recently, some producers have started to once again produce tracks with slower tempos (that is, in the 150-170 bpm range), but the mid-170s tempo is still a hallmark of the drum and bass sound.
