Black migrant workers use of the Harmonica in '50s Blues spread all over America, and subsequently worldwide. Bob Dylan and bands such as Led Zeppelin took influence from 1950s blues and embraced the Harmonica as the alternative solo instrument to the guitar. Other notable appearances of the harmonica include Pop legend Stevie Wonder's solo 'Isn't She Lovely'. Made from a simple comb-like body and mouthpiece, the harmonica is the Rock and Country musician's secret weapon.
