Bop Contrasted with Swing
Bop differed from swing in a number of performance aspects:
- Preferred instrumentation for bop was the small combo instead of big band.
- Less emphasis was placed on arrangements in bop.
- Average tempo was faster in bop.
- Clarinet was rare in bop.
- Display of instrumental virtuosity was a higher priority for bop players.
- Rhythm guitar was rare.
Bop differed from swing in a number of stylistic respects:
|1.||Bop improvisation was more complex because it contained|
|a) more themes per solo,|
|b) less similarity among themes,|
|c) more excursions outside the tune’s original key, and|
|d) a greater scope of rhythmic development.|
|2.||Melodies were more complex in bop.|
|3.||Harmonies were more complex in bop.|
|4.||Bop tunes and chord progressions projected a more unresolved quality.|
|5.||Accompaniment rhythms were more varied in bop.|
|6.||Comping was more prevalent than stride style and simple, on-the-beat chording.|
|7.||Drummers played their timekeeping rhythms primarily on suspended cymbal, rather than snare drum, high-hat, or bass drum.|
|8.||Surprise was more highly valued in bop.|
|9.||Bop was a more agitated style than swing was.|
