How to Play Rock: Where It Came From, How the Styles Differ, and the Backbeat, Power Chords and Riffs Behind the Sound

In 1957, at a record hop in Fredericksburg, Virginia, a guitarist named Link Wray improvised an instrumental on stage, and when one of the microphones was stuck up to an amplifier, it gave the tune its distorted sound. When he tried to record it, the sound was gone, so, as he later told Guitar magazine, he "got a pen and started punchin' holes in the tweeters." The record, "Rumble," came out in April 1958, according to the Library of Congress essay that marks its place in the National Recording Registry. That mix of a strong beat, a loud electric guitar and a little do-it-yourself damage runs all through rock. This guide shows where the sound came from and how the main styles differ in ways you can hear. Then it gives you four things to play: the rock beat, power chords, a riff with palm muting and a first pentatonic solo, each with a free worksheet.

What makes music "rock"

Rock is hard to define, even for experts. In Britannica's entry, the sociologist Simon Frith writes that there is "basic agreement" that rock "is a form of music with a strong beat," but that it is difficult to say much more. He notes that the music emerged in the United States in the 1950s and spread across the English-speaking world and Europe in the 1960s. He also quotes a working definition from the Canadian government that makes a handy checklist for players: a strong beat, the use of blues forms, and rock instruments such as electric guitar, electric bass, electric organ or electric piano. Frith adds that "rock" was coined to set some music apart from pop, and what was at issue was "less a sound than an attitude."

For a player, the band is the clearest place to start: each instrument has a job.

Four jobs in a rock band. In a small band, one guitarist often plays both guitar parts.

If you don't own a guitar or an amp yet, start with our guide to choosing the right guitar for beginners, which covers electric guitars, amps and your first open chords.

Where rock came from, 1938 to 1958

Rock grew out of Black American music: gospel, blues and rhythm and blues. The Guardian's Alexis Petridis puts it bluntly: the first white artists to make rock and roll records were interpreting "a sound already well-established by black musicians almost a decade before."

Gospel gave rock its first guitar hero. The Rock & Roll Hall of Fame calls Sister Rosetta Tharpe "the first guitar heroine of rock & roll," and its essay places her on the stage of New York's Cotton Club in the fall of 1938. Britannica says she sang traditional gospel songs with jazz tempos on electric guitar, and that her work influenced early rock and rollers such as Chuck Berry, Jerry Lee Lewis, Little Richard and Elvis Presley.

The blues supplied the electric guitar sound and the forms. The Hall of Fame says Muddy Waters "electrified the blues." Rhythm and blues, the name Billboard gave its chart of Black popular records in June 1949, supplied the beat and the small band.

Which record came first? There is no agreed answer. The Mississippi Blues Trail marker for "Rocket 88" says the 1951 record by Jackie Brenston and his Delta Cats "has often been cited as the first rock 'n' roll record." The Delta Cats were really Ike Turner's Kings of Rhythm. On the trip to Sam Phillips's studio in Memphis, the guitarist's amplifier fell out of the trunk, and Phillips said he stuffed its broken speaker cone with brown wrapping paper. Many historians, the marker says, point to that distorted buzz and the driving boogie rhythm as the reasons the record counts.

Pianists have a place in the story too. The Hall of Fame praises Fats Domino's "rolling boogie-woogie piano" and Little Richard's "thunderous piano," and Domino's page credits Billy Joel, who inducted him in 1986, with the line "the man who proved that the piano was a rock and roll instrument." In New Orleans, the session drummer Earl Palmer provided the backbeat on records by both, according to his Los Angeles Times obituary.

Country music was the other root. Chuck Berry's "Maybellene" (1955) was adapted from the country tune "Ida Red," and Britannica says it climbed to number five on the pop chart. In July 1954 Elvis Presley's first session for Sun Records produced "That's All Right," a blues by Arthur "Big Boy" Crudup, and "Blue Moon of Kentucky," a bluegrass song by Bill Monroe. Presley on acoustic guitar, Scotty Moore on electric guitar and Bill Black on slapped upright bass became, in Britannica's words, rockabilly's "quintessential instrumentation."

The beat was different then, too. The musicologist Alexander Stewart found that the earliest rock 'n' roll and rockabilly were "predominantly in shuffle rhythms," with each beat split long–short, and that by the 1960s rock had moved to even eighth notes. You can feel the change in one bar. Below, the common "boogie" shape (root and 5th, then root and 6th) is played both ways.

The boogie shape in A: the 5th (E) twice, then the 6th (F♯) twice, over the open A string. Marked Shuffle, the written eighths are played long–short, as the middle staff shows; marked Straight, they are even. The boogie adds the 6th to the A5 shape. On bass, play only the bottom note.

Play the bar with a metronome at about 120, shuffled four times and then straight four times. If the long–short feel is new to you, Swing Eighths explains the marking, gives you a two-bar riff to practice both ways, and files "most rock and pop" under "keep it straight." The eighth note and Time Signatures I: Simple Time cover the counting, and The 12-Bar Blues gives you the chord map that early rock 'n' roll borrowed.

How the main styles differ: a map for players

Each later style changed something you can hear: the beat, the tempo or the guitar sound. Here is a short map.

Ten milestones, with years from the Rock & Roll Hall of Fame, Britannica, the Library of Congress and the Mississippi Blues Trail. Led Zeppelin II came out in 1969; the "c. 1970" covers the three heavy albums together.

• The British Invasion. Britannica says the Beatles and the Rolling Stones were "hugely influenced by Berry." The Hall of Fame describes the Beatles' mix of 1950s rock and roll, tight harmonies and "a Motown-inspired groove." Listen for the straight eighths of the new decade.
• The riff takes over. Britannica says the Kinks' "You Really Got Me" (1964) influenced the early Who, American garage punk of the mid-1960s and the heavy metal of the early 1970s. Listen for how one short power-chord riff carries the whole song.
• Psychedelic rock. Britannica dates it from 1966 and lists "feedback, electronics, and intense volume." The Hall of Fame credits Jimi Hendrix with expanding on blues through feedback and extended improvisation.
• Hard rock and heavy metal. Robert Walser, writing for Britannica, says Cream, the Yardbirds, the Jeff Beck Group and Hendrix are generally credited with the heavier drums, bass and distorted guitar. Led Zeppelin, Deep Purple and Black Sabbath set the sound down around 1970 with Led Zeppelin II (1969), Deep Purple in Rock and Paranoid, records with "heavy riffs, distorted 'power chords.'" Later thrash bands are known for fast tempos.
• Progressive rock. Britannica calls it "intellectual" album-oriented rock by British bands such as Genesis, King Crimson, Pink Floyd and Yes, and the Hall of Fame praises Yes for "complex, progressive, and virtuosic rock suites." Listen for long, multi-part pieces.
• Punk. In Jon Savage's Britannica entry, punk coalesced as a movement in 1975–80 around clubs such as CBGB in New York, and the Ramones' 1976 debut album "became the blueprint." Listen for speed: hardcore, in the early to mid-1980s, "further accelerated punk's breakneck tempo."
• Alternative rock and grunge. Britannica says this music "built on distorted guitars" grew out of a decade of college rock (R.E.M. is the Hall of Fame's example) and dominated rock between 1991 and 1996, after Nirvana's Nevermind (1991).

You can hear three of those sounds by playing one idea three ways. The figure below takes E for a bar and then G and A, and dresses it as 1950s rock 'n' roll, as heavy rock and as punk.

One chord plan, three styles. Top: the shuffle and boogie shapes of the 1950s. Middle: long, heavy power chords; try them over the half-time drum feel shown below. Bottom: straight eighth-note downstrokes at a fast tempo. The tempos are suggestions, not any band's.

The backbeat: the pulse every rock band locks to

If one thing makes a band sound like rock, it is the backbeat. Open Music Theory, a free university textbook, defines it as "an accented articulation on beats two and four in quadruple meters, usually played by the snare drum," and adds that in many genres the snare backbeat is the most stable layer of the beat.

The textbook's "standard rock beat" has three layers: the kick drum on beats 1 and 3, the snare on 2 and 4, and steady eighth notes on the hi-hat. On paper, drums use a percussion staff. The kick sits in the bottom space, the snare in the third space, and the closed hi-hat is an x above the staff; cymbals take stems up and drums stems down.

The standard rock beat. Count the eighths out loud (the counts are printed above the hi-hat) and the snare always lands on "2" and "4."

You don't need a drum kit to learn it. Set a metronome to about 70 (Yamaha's Steve La Cerra suggests that beginning drummers start around 70 BPM and notes that playing slow is harder than playing fast), count "1 & 2 & 3 & 4 &," and clap only on 2 and 4. Then tap your foot on 1 and 3 while you clap. Our article on the difference between rhythm and meter explains why beats 1 and 3 feel strong, and Write the Counts and Ear Training: Rhythm Dictation train the counting and listening.

Locking in means everyone plays on the same grid. In the next figure the guitar plays a two-note power chord on every eighth, the bass plays the root on every eighth and leans on the notes where the kick lands, and the drums play the standard beat.

The band locked together. Guitar and bass both play eighths; the bass accents fall where the kick drum plays (beats 1 and 3) and on each chord change. The bass part sounds an octave below where it is written.

Pianists can join the same grid: play the roots in eighths with the left hand, like the bass, and chords on 2 and 4 with the right hand, with the snare.

Drummers also change the feel without changing the tempo. Open Music Theory describes a half-time feel, where the backbeat moves at half speed and the snare plays only on beat 3, and a double-time feel, where it moves twice as fast and the snare plays on the second eighth of every beat.

Same tempo, three feels. Only the snare and kick move; the hi-hat keeps the same eighths, so the song's beat stays where it was.

Power chords: the root, the 5th and no 3rd

A power chord is the root and the 5th of a chord, often with the root doubled an octave higher. Britannica's entry on Link Wray defines it as "a simplified chord, commonly played on the electric guitar, based on the root and fifth notes." Guitar music names it with a 5: E5, A5, G5. The interval is the one our Intervals: the 5th sheet describes as "wide open, strong, almost hollow."

What's missing is the 3rd, the note that decides whether a chord is major or minor (our music theory for beginners guide shows how chords stack root, 3rd and 5th). Major & minor: two colors of home shows that lowering the 3rd turns major into minor; Suspended chords: sus2 and sus4 shows chords that replace the 3rd with a 2nd or 4th. A power chord simply leaves it out, so it is neither major nor minor.

E major and E minor differ by one note, the 3rd (G♯ or G). E5 keeps only the root, the 5th and the octave, the three lowest strings: open E, then fret 2 on strings 5 and 4.

On "Rumble," distortion and the power chord came together. Britannica says Link Wray is "often credited with introducing the power chord" and was among the first electric guitarists to experiment with distortion; the Hall of Fame goes further and says that with "Rumble" Wray "invented power-chord rock." Walser names distorted power chords as one sign of the heavy sound Led Zeppelin, Deep Purple and Black Sabbath "codified in the 1970s." Try the combination yourself with some overdrive on your amp: strum a full E major, then play the three-note E5, and listen to which one stays clear.

The best thing about power chords is that one shape works everywhere on the neck. With the root on string 6 or string 5, the 5th sits on the next string two frets up, and the octave sits beside it.

Two movable shapes. Slide the left one to fret 3 for G5 or fret 7 for B5, and the right one to fret 3 for C5 or fret 7 for E5. Use the side of your fretting fingers to mute the strings you don't play.

Rock songs move these shapes through the same few chord progressions again and again: I–IV–V, the borrowed ♭VII and the 12-bar blues. Our article on common chord progressions in popular music covers them, with power chords at the piano, and The primary chords: I, IV & V names the three chords you will meet most.

Riffs: short, repeated, built on the minor pentatonic

A riff is a short figure that repeats under a song, usually one or two bars long. Classical musicians call a repeating pattern an ostinato, and our The Ostinato sheet says "every looped bass line in pop music is an ostinato too." A good riff also works like a motif: one short idea that comes back the same, changed or moved, as Motif and sequence explains.

Many rock riffs, especially heavy ones, come from the minor pentatonic scale. The theorist Walter Everett writes that heavy metal's emphasis on power chords "begins with doublings of the minor-pentatonic scale." In E, that scale is E, G, A, B and D, and on guitar its lowest notes fall on the open strings and frets 2 and 3. Here is an original riff that uses only those notes.

A one-bar motif on E minor pentatonic, then the same start with a new ending that climbs B–D–E. Play bar 1 with the open low E and fret 3 (G), then the open A string.

The second riff uses power chords on the same scale's notes, E, G and A, and adds the most useful rhythmic trick in rock: the push. The chord arrives on the "&" just before a beat and holds over it, which is syncopation. Syncopation explains the idea, and The Rests covers the silences that let a riff breathe.

Two pushes: G5 arrives on the "&" of 2 and holds through beat 3; A5 arrives on the "&" of 3 and holds through beat 4. Count every eighth out loud, and feel the quarter rest in bar 2 as part of the riff.

Play both riffs slowly with a metronome before you speed up, and hold the tied chords for their full length. To work out a riff from a record, our guide to how to play by ear shows the steps.

Palm muting: chug against ring

Palm muting gives rock rhythm guitar its tight, percussive "chug." In a Guitar World lesson, Jude Smith explains the hand position: rest the picking hand gently on the strings just before they pass over the bridge, and lightly touch them with the edge of your palm. Move the hand farther from the bridge and the notes sound more choked, until they have no sustain at all. Guitar World's Jimmy Brown notes that guitar music marks the technique with the abbreviation "P.M."

Try it on the E5 shape (the low E and A strings): pick slowly, slide the palm a little toward the neck, and listen for the point where the note turns into a thud. The chug you want is just before it.

Muted eighths under the P.M. dashes, then open, accented chords that ring. Lift the palm for the G5 and A5 and let them sound for their full value.

The contrast is the point. In another Guitar World lesson, Jamie Hunt notes that players often create accents not by playing harder but by reducing the muting or leaving it off, so the open notes come out bright against the tight ones. For the marks themselves, Fermata, Tenuto & Accent explains the accent and Legato or Staccato? trains your eye for short versus connected notes.

The minor pentatonic in solos

For solos, guitarists move up the neck to the "box": A minor pentatonic at the 5th fret, the notes A, C, D, E and G with two notes on every string. Yamaha's Robbie Calvo calls this shape, minor pentatonic pattern 1, the first scale shape most guitarists learn. If you played the open E minor pentatonic in our beginner guitar guide, this is the same scale type in a new key and position, and the box itself can start on any fret.

A minor pentatonic in the 5th-fret box, two notes per string. Frets 5 and 8 on strings 6, 2 and 1, frets 5 and 7 on strings 5, 4 and 3. Play it up, then back down.

On the neck, the box is easy to see: two notes per string, with your index finger on fret 5 the whole time.

The same twelve notes on the neck. The three A's (in cyan) are your home notes; aim for them at the ends of phrases.

The magic trick of blues-based rock is to play this minor scale over a major-key band. Everett describes blues-based rock as coloring "a structural major mode with minor-pentatonic melodic borrowings." Over an A major chord, the scale's minor 3rd (C) rubs against the chord's C♯. Playing minor pentatonic over a dominant chord, Calvo writes, you'll probably want to bend the minor 3rd a little "to at least imply the major third." In our phrase the band plays bare A5 chords, but the key is still A major, so the slightly bent C still sounds bluesy. On guitar, push the string slightly toward the ceiling while it rings, a quarter-tone bend.

Pianists can play along with the same five notes. Our Improvising with the Pentatonic sheet points out that A minor pentatonic uses the same keys as C major pentatonic, "Same keys, different home," and The Pentatonic & Blues Scales adds the blues scale (shown in C; start the pattern on A to match the band).

Improvising with the Pentatonic also gives a four-step recipe for a solo: "Pick a rhythm," "Repeat it, change the notes," "Leave some space," and "End on the home note." The original phrase below follows it over a band playing A5, D5, A5, then E5 and A5.

A question (bars 1–2) and an answer (bars 3–4). Bars 1, 3 and 4 share one rhythm, bar 2 ends with a rest, and the phrase ends on a long A. The C in bar 3 is the bluesy note: bend it a quarter tone toward C♯.

When the phrase feels easy, make your own with the same rhythm, then try the box over the 12 bars of The 12-Bar Blues. If the band's chords use the lowered 7th, G in the key of A (the ♭VII chord), you are in the sound that The modes sheet links to Mixolydian and "countless folk and rock songs."

A 15-minute rock workout

Keep a metronome on for every step: start slow, and speed up only a few clicks at a time when a step is clean, as Tempo & the Metronome recommends.

Fifteen minutes, four steps. Drummers can swap step 2 for the half-time and double-time grooves.

1. Three minutes of beat: clap on 2 and 4 while your foot taps 1 and 3, or play the standard rock beat.
2. Four minutes of power chords: move the E5, G5 and A5 shapes in quarter notes, then in eighths.
3. Four minutes of riff: the syncopated riff, then the palm-mute chug with open accents.
4. Four minutes of solo: the box up and down once, then the four-bar phrase, then a phrase of your own.

On harder days, use the fix-it loop from How to practice: stop, find the exact notes, play them slowly, and get three clean in a row before you put them back in.

Play it with a band

Rock grew from gospel, blues, rhythm and blues and country, and each style since has changed the beat, the tempo or the guitar sound. Underneath them all sit the same few skills: a backbeat on 2 and 4, power chords that leave out the 3rd, short riffs on the minor pentatonic, palm muting against open chords, and solos that ask and answer. Learn them slowly, with a metronome, and then play them with other people.

A Tissimo guitar teacher or drum teacher can listen in a live online lesson and tell you whether you are really locked to the backbeat and whether your muted notes are tight enough.
