The blues idiom offered early twentieth century musicians a new way to share deep emotional feelings vigorously and honestly.
A hundred thirty years earlier, Mozart had reveled in the fresh, airy lightness of the major tonality which superseded stolid Renaissance modal forms around 1600.
Periodic innovations like these keep music vibrant and invigorating. Unfortunately, too many of today’s musicians bloat their playing with endless, unimaginative, repetitive blues licks. Sure, blues licks can add a funky edge, but overuse of these clichés leads to tiresome monotony.
