Hard bop
Jazz style of the 1950s that combines bebop with blues and gospel elements.
What it means
Hard bop is a jazz style of the 1950s that combines bebop with elements of blues and gospel. It carries on the virtuosity and harmony of bebop but sounds earthier, more powerful, and rhythmically more driving, and puts blues expression and groove more in the foreground.
Musical use
The style arose above all on the East Coast of the United States and was a response to the calmer, often more restrained cool jazz of the West Coast. Defining were Art Blakey and his Jazz Messengers, the pianist Horace Silver, and the quintet of Clifford Brown and Max Roach. Typical are blues phrases, gospel-like chord progressions, strong bass lines, and a driving drum pulse. The scoring is usually a quintet of trumpet, saxophone, piano, bass, and drums.
Hard bop should be distinguished from bebop, from which it emerged and which is faster, more complex, and less close to the blues, and from cool jazz, which sounds quieter and more balanced. It differs from later free jazz through its tie to chord progressions and fixed forms.
Performance practice
In hard bop, listen for the link between blues and bebop and take time for an earthy, grooving tone. If you improvise, use blues phrases and rhythmic emphases against the pulse, and respond to your fellow musicians instead of merely playing scales.
