The Basic Chord Progression and Tuning

Folsom Prison Blues uses standard tuning and relies on three chords: E, B, and A. The song sits in the key of E, which makes it accessible for players who know basic open-position chords. If you already play barre chords, you can move the progression up or down the neck, but the original recording uses open E, so starting there will match what you hear on the record.

The main progression repeats throughout most of the song: E for four measures, then B for two measures, then A for one measure, then B for one measure. This eight-measure cycle is the backbone of every verse and the chorus. Once you can play this progression cleanly and keep time, you have the harmonic structure locked.

The rhythm pattern matters as much as the chords themselves. Johnny Cash's version uses a steady, driving eighth-note strumming pattern with a slight emphasis on the downbeats. Start by strumming down on each beat, then add down-and-up strokes on the eighth notes between beats. Keep the motion consistent even when you change chords—do not stop to reset your hand position.

Key Takeaways

  • The song uses three chords in E major (E, B, and A) in a repeating eight-measure pattern that works for every verse and chorus.
  • Standard tuning and open-position chords make this song playable for intermediate beginners, though clean chord changes under tempo take practice.
  • The rhythm is an eighth-note strumming pattern with steady downstrokes, not a fingerpicking pattern, so focus on consistent hand motion rather than individual strings.
  • The intro and outro use a single-note riff on the low E string that outlines the E chord—learning this riff by ear or tab will help you nail the song's character.

The Intro Riff and How to Play It

The opening riff is one of the most recognizable parts of the song. It is played on the low E string (the thickest string) and uses only a few frets. The riff starts on the open E string, moves to the second fret (F#), then to the fourth fret (G#), and back down. This three-note pattern repeats and outlines the E major chord without playing the full chord shape.

To learn this riff, use a guitar tab or slow down a recording and pick out the notes one at a time. The timing is straightforward—each note lands on a steady beat with no complex rhythms. Once you have the fret numbers memorized, practice playing the riff at a slow tempo until your fingers land cleanly on each fret without buzzing or muting adjacent strings. The goal is a clear, punchy tone on each note.

After you can play the riff smoothly, practice transitioning from the riff into the first chord (E major). Many players stumble here because they rush or do not prepare their fingers ahead of time. Before you finish the last note of the riff, your other fingers should already be moving toward the E chord shape. This overlap makes the transition seamless and keeps the song flowing.

Strumming Technique and Keeping Time

The strumming pattern is steady and driving, not syncopated or complex. Use a pick and aim for a consistent eighth-note rhythm: down, up, down, up, down, up, down, up. Each pair of down-up strokes fills one beat, so in a measure of four beats, you play eight pick strokes. The emphasis falls on the downbeats (beats 1, 2, 3, and 4), so your downstrokes should be slightly louder or more deliberate than your upstrokes.

The challenge is maintaining this pattern while changing chords. Most beginners either stop strumming to move their fingers or rush the chord change and lose the rhythm. Instead, keep your picking hand moving at the same speed throughout—even if your fretting hand is not quite ready for the next chord, your pick keeps going. This trains your hands to work independently and keeps the song from sounding choppy.

Practice with a metronome set to 120 beats per minute (the approximate tempo of the original recording). Start at 80 or 90 bpm if that feels too fast, and gradually increase the speed as your chord changes become automatic. The goal is to play the progression without looking at your hands or thinking about which chord comes next.

Chord Changes: E to B to A and Back

The E chord is an open-position chord that uses three fingers: index on the first fret of the G string, middle on the second fret of the A string, and ring on the second fret of the D string. The high E string and low E string ring open. This shape is one of the first chords most players learn, so it should feel natural.

The B chord is a barre chord in the original key. Your index finger presses down on the second fret across all six strings, and your other fingers form the shape of an E chord two frets higher. For beginners, this is the hardest chord in the song because it requires finger strength and pressure across the entire fretboard. If the barre chord feels impossible, you can play a simplified B7 chord using only the lower strings, though it will not sound exactly like the recording.

The A chord uses three fingers: index on the first fret of the B string, middle on the second fret of the D string, and ring on the second fret of the G string. The A and high E strings ring open. This chord is easier than the B barre chord and should be comfortable once you have played it a few times.

Practice each chord change in isolation before putting them together. Play E for four measures, then switch to B and hold it for two measures. Repeat this pair until the change is smooth. Then add the A chord and practice E-B-A-B as a four-chord sequence. Only after each individual change feels automatic should you try playing the full progression at tempo.

Verse and Chorus Structure

Every verse of the song follows the same eight-measure chord progression: E (four measures), B (two measures), A (one measure), B (one measure). The lyrics change with each verse, but the chords and rhythm stay identical. This repetition makes the song easier to learn because you only have to memorize one progression and explore it throughout.

The chorus uses the same progression and the same strumming pattern. The only difference is the melody and lyrics—the underlying chords do not change. This means once you have the progression down, you can play the entire song without learning new chord shapes or rhythms.

The outro typically repeats the intro riff or a variation of it, played over the E chord. Some versions fade out on the E chord with the riff repeating, while others end with a single strum of E. Listen to the recording you are learning from and match the ending they use.

Common Mistakes and How to Fix Them

The most common mistake is playing the B barre chord incorrectly. Many beginners either do not press hard enough (causing muted or buzzing strings) or do not place their index finger straight across all six strings. The fix is to practice the B chord without the other fingers first—just the barre alone. Press down and pluck each string individually to make sure all six ring clearly. Only after the barre is solid should you add the other fingers.

Another frequent problem is rushing the chord changes. When you move from E to B, there is a natural pause as your fingers reposition. Beginners often speed up during this pause, throwing off the tempo. Use a metronome and force yourself to keep the same strumming speed even if the chord change is not quite ready. Your hand will catch up with practice.

A third issue is muting strings accidentally during chord changes. When you move your fingers from one chord to the next, a finger might brush a string and dampen it. This creates a dead or muted sound in the middle of a strum. The solution is to lift your fingers slightly higher off the strings during the change—do not drag them across the fretboard.

Variations and Alternate Approaches

If the B barre chord is too difficult, you can play a simplified version using only the lower four strings (E, A, D, and G). This creates a B7 sound rather than a pure B major, but it is playable and sounds acceptable in context. As your finger strength improves, transition to the full barre chord.

Some players use fingerpicking instead of strumming. The song works with fingerpicking, but it requires a more complex pattern and does not match the original recording as closely. Stick with strumming if you are learning the song for the first time.

You can also transpose the song to a different key if E is uncomfortable. Moving the entire progression down two frets puts it in D major, which uses open chords (D, A, and G) and no barre chords. This is easier for beginners, though it will not match the original recording's pitch.

Frequently Asked Questions

Do I need to use a pick or can I play with my fingers?

A pick produces the bright, punchy tone of the original recording and makes the steady eighth-note strumming pattern easier to control. Fingerpicking is possible but requires a different technique and does not sound as close to the original. Start with a pick.

What if I cannot play the B barre chord cleanly?

Practice the barre alone without the other fingers until all six strings ring clearly. Build finger strength gradually by holding the barre for longer periods. You can also simplify to a B7 chord using only the lower strings while you develop the strength for a full barre.

How long does it usually take to play this song all the way through?

If you already know basic open chords and can change between them smoothly, you can learn the progression in a few days of practice. Playing the entire song cleanly at tempo typically takes one to two weeks of regular practice, depending on your experience level.

Should I learn the intro riff or can I skip it?

The riff is iconic and worth learning because it makes the song when ready recognizable. It is also easier than the full chord progression, so it is a good starting point. You can play the song without it, but including it adds authenticity and gives you a clear way to start and end.

Can I play this song in a different tuning?

The song is written for standard tuning and sounds best in that tuning. You can transpose it to a different key while staying in standard tuning, but switching to an alternate tuning (like drop D or open E) changes the character of the song and requires relearning the riff and chord shapes.
