Why This Intro Is So Challenging
Extreme speed
One of the fastest rock guitar intros ever recorded. The pull-offs are relentless and the tempo is punishing. At full speed, it's a blur.
Stamina and endurance
The intro lasts 30+ seconds of non-stop pull-offs. Your fretting hand has to maintain even volume and timing as it fatigues. It's a marathon, not a sprint.
Consistency and evenness
Every pull-off needs to sound identical. Same volume, same clarity, same timing. Any unevenness is obvious. It's technically and mentally demanding.

Slow it down to 40%
Start at 40-50% speed. This is one of the fastest intros in rock. At slower speeds you can see the finger positions and hear each pull-off clearly.
Loop the opening pattern
The intro uses a repeating pattern of pull-offs on the B string. Set an AB loop on the first 8-10 seconds and drill it until the pull-offs are clean.
Build stamina gradually
Practice playing the full 30-second intro at slow speed without stopping. Focus on maintaining even volume and timing as your hand tires.
Increase speed very slowly
Work from 40% through 50%, 60%, 70%, 80%, and finally full speed. Take weeks if needed. Rushing this builds sloppy technique.
Speed Progression Plan
Learn the pattern and fingering
Identify the pull-off pattern on the B string. Practice pulling off cleanly so each note rings clear. Don't rely on picking - the pull-off should generate the sound.
Build consistency
At 60%, the pattern starts to flow. Focus on making every pull-off identical. No accidental volume spikes or dead notes. Consistency is everything.
Work on stamina
At 80%, the full intro becomes a real stamina challenge. Your hand will fatigue. Practice maintaining evenness even when tired. This is the hardest stage.
Master the full-speed intro
At full speed, it's exhilarating. If any section falls apart, isolate it with a loop and drop back to 60%. Nail this and you've joined the ranks of serious rock guitarists.

Frequently Asked Questions
How hard is Thunderstruck to play on guitar?
It's very difficult. The intro requires rapid pull-offs at high speed for 30+ seconds non-stop. It demands finger strength, stamina, evenness, and consistency. Most guitarists take weeks or months to build up to full speed. It's a rite of passage for rock guitarists.
What technique is used in the Thunderstruck intro?
The intro uses legato pull-offs on the B string. Angus Young picks the first note, then pulls off repeatedly without picking again. It creates a machine-gun effect. The challenge is keeping the volume and timing consistent across all the pulled-off notes.
What speed should I start practising Thunderstruck at?
Start at 40-50% speed. This is one of the fastest intros in rock. At slower speeds you can focus on clean pull-offs, even volume, and correct fingering. Don't rush to full speed - sloppy technique at speed is worse than slow perfection.
Does slowing down change the pitch?
No. PracticeLoop preserves the original pitch at all speeds. The intro stays in B major whether you're at 40% or 100%, so you can play along accurately at any speed.
