A bass song is a piece of music that contains low frequency notes, or bass. Bass notes can be acoustic, but within the term "bass song" they are usually synthesized, typically sine waves or very similar. The term "bass song" typically refers to hip hop, trap, dubstep, techno, reggae, or other electronic music genres. However, there are cases where other genres and even acoustic music contain considerable bass content, either acoustically produced, or synthesized.

Sub-bass sounds are those approximately below 60  Hz and extending downward to include the lowest frequency humans can hear, typically 20 Hz. In this range, human hearing is not very sensitive, so sounds in this range tend to be felt more than heard.

Sub-bass energy is popular in dance music, where the low frequencies involve energy from the kick drum, the bass guitar and electronic synthesizers. Particular genres such as drum and bass and dubstep often feature the whole bass-line produced in sub-bass frequencies.
