Final answer:
T-Bone Walker was a pioneer in using the electric guitar as a solo blues instrument, which allowed for greater expression and volume in performances.
Step-by-step explanation:
T-Bone Walker was among the first musicians to use the electric guitar as a solo blues instrument. Instruments like the banjo, fiddle, and acoustic guitar were widely used in folk and early blues music, particularly because they were louder and could be heard in large gatherings like barn dances. The introduction of the electric guitar, which could be amplified, revolutionized blues music, allowing artists like T-Bone Walker to develop a new style of playing that catered to louder and larger venues. This was part of a broader adaptability among musicians, reminiscent of how early hip hop evolved in the Bronx. Such examples include adaptive strategies where quieter instruments like the mandolin and the dulcimer were played more rhythmically to increase volume.
