Man, trying to nail 'Thunderstruck' is like trying to tame a lightning bolt—it's wild, fast, and electrifying! The key is in the iconic opening riff vocalization. You don’t just sing 'Thunder!'—you become the thunder. Start by practicing the staccato 'Ah-ah-ah-ah' parts with sharp, punchy breaths, almost like you’re gasping between strikes. Angus Young’s guitar is your rhythm guide; listen for those rapid-fire sixteenth notes.
Then there’s the chorus—Brian Johnson’s rasp is legendary, but don’t shred your voice trying to mimic it perfectly. Focus on pushing from your diaphragm, not your throat. And when you hit 'THUNDER!', imagine you’re shouting across a stadium. Bonus tip: Air guitar isn’t optional. It’s mandatory. If your arms aren’t windmilling by the end, you’re doing it wrong.
