Not that many musical genres beginning with a number - strange really considering that music is all about beats and numbers - gotta love a bit of 2 tone though.
2-step garage – chaotic style of UK garage.
2 Tone – late-1970s UK ska revival which fused ska with punk rock.
4-beat – breakbeat hardcore subgenre played between 150 and 170 BPM consisting of a fast looped breakbeat and a drum at every 4 beats.
12-bar blues – A distinctive form predominantly based on the I-IV-V chords of a key.
