Although “Texas Flood” has three verses of lyrics, the song is more of a prolonged guitar solo, allowing Vaughan to show off his characteristic electric blues style. Stylistically, “Texas Flood” is structured around the standard three-chord blues progression. Written and performed in the key of G (which sounded in F# because Vaughan tuned his guitar half a step down), it is in 12/8 time, or compound time, which gives it a “slow-burning” feel that is common in Texas blues.
