A guitar intro is a signature you hear before the singer has earned a word. These ten still stop a room.
10Black Sabbath – “Iron Man” Tony Iommi’s footsteps and the two-note stomp open Paranoid like a door in a factory. The riff came out of a damaged hand and a downtuned SG, and it still sounds like something walking toward you. Three notes, and the room already knows the name.
9Chuck Berry – “Johnny B. Goode” The 1958 intro is the whole grammar of rock guitar, doubled with Johnny Johnson’s piano until the two are one engine. Berry wrote a country boy who could play, then played the proof himself. Every guitarist who starts a solo with that climb is quoting a letter home.
8The Kinks – “You Really Got Me” Dave Davies slashed his speaker cone with a razor, and the 1964 single came out snarling. The riff is two chords and a grievance. It is also the door that garage rock, punk and a lot of metal later walked through without knocking.
7Jimi Hendrix – “Purple Haze” The tritone at the top of Are You Experienced is a wrong note that became the right one. Hendrix recorded it in London in 1967, with Noel Redding and Mitch Mitchell, and the intro still feels like the ceiling lifting. You do not hum it. You flinch, then smile.
6AC/DC – “Back in Black” Angus and Malcolm Young wrote the riff in the weeks after Bon Scott’s death, and the 1980 title track opens like a bell tolling in a car park. Brian Johnson had not yet earned the myth. The guitar already had. It is grief with a backbeat, and it does not apologize.
5Led Zeppelin – “Whole Lotta Love” Jimmy Page’s riff on Led Zeppelin II, 1969, is a single figure that makes the rest of the song feel inevitable. The theremin comes later. The intro is enough. It is the sound of a band deciding that space, not speed, is the threat.
4Nirvana – “Smells Like Teen Spirit” Four chords, quiet then loud, recorded with Butch Vig for Nevermind in 1991. Kurt Cobain said he was trying to write a Pixies song. The intro became the decade’s doorbell. You hear the clean figure and your shoulders already know the crash.
3Guns N’ Roses – “Sweet Child O’ Mine” Slash has said the opening figure was a finger exercise, a joke in a rehearsal room, before Appetite for Destruction in 1987 made it a global signature. The Les Paul climbs like a question the song never quite answers. Overplayed, yes. Still unbeaten as a hello.
2The Rolling Stones – “(I Can’t Get No) Satisfaction” Keith Richards woke up with the riff, recorded it on a cassette, and the 1965 single put a Maestro fuzz pedal where a horn section might have been. The intro is a complaint you can dance to. Sixty years on, the fuzz still sounds like a grudge.
1Deep Purple – “Smoke on the Water” Ritchie Blackmore’s four-note figure was written after the Montreux Casino burned in December 1971, during the Frank Zappa concert that Machine Head turned into a lyric. The riff is so plain it should not have lasted. It outlasted the building. Hum two notes anywhere and a stranger finishes them.
