What music is 70 BPM?
Slow (60 to 79 BPM). This is a slow tempo. Slow songs, ballads and laid back grooves live here, and a long note or a long delay tail has plenty of room. Because each beat is long, small timing differences are easy to hear, so slow tracks reward a tight, deliberate groove.
Typical tempo ranges that include 70 BPM: Ballads, Reggae, R&B, Downtempo and trip hop, Lofi hip hop.
Half time: 35 BPM, slower than the genre ranges listed here. Double time: 140 BPM, in the typical range of Rock, Techno, Trance, UK garage, Trap (often felt at half time), Dubstep (felt at half time).
A track can be written at one tempo and felt at the other, so a song at 70 BPM may be counted as 35 or 140 in a DAW or DJ software. Ranges are typical only; plenty of songs sit outside them.
