The B7 chord uses your index finger on the second fret of the A string, middle finger on the fourth fret of the D string, ring finger on the fourth fret of the G string, and pinky on the fourth fret of the high E string—leaving the B string open and muting the low E string.

B7 is a dominant seventh chord that appears in blues, rock, and jazz. It's harder than basic open chords because your fingers bunch together on the higher frets, but the shape becomes automatic with repetition. Most players find it takes a few weeks of daily practice to hold it cleanly without buzzing or muting adjacent strings by accident.

The chord sits in the second position on the neck, which means you're not playing the lowest strings the way you do with open chords like E or A. This is the main reason it feels awkward at first—your hand position shifts higher, and your fingers have less room to spread.

Key Takeaways

  • Place your index finger on the A string at the second fret, then stack your middle, ring, and pinky fingers on the D, G, and high E strings at the fourth fret.
  • Leave the B string open (don't play it) and mute the low E string by resting the side of your index finger against it.
  • Press down hard enough that each string rings clearly without buzzing, which usually means your fingertips should be just behind the fret wire, not on top of it.
  • Practice the finger placement without strumming first, then add slow strums once you can hold the shape for five seconds without pain.

Finger Placement Step by Step

Start with your guitar in playing position. Look at the fretboard so you can see what you're doing—there's no shame in watching your hands while you learn. Place your index finger on the A string (the fourth string from the top) at the second fret. Press down firmly, about a quarter-inch behind the fret wire. Your fingertip should be on the string itself, not the flesh of your finger.

Now place your middle finger on the D string (the third string) at the fourth fret. Your middle finger will be two frets higher than your index finger, so it sits further down the neck. Press it down with the same pressure. Next, place your ring finger on the G string (the second string) also at the fourth fret, right next to your middle finger. Finally, place your pinky on the high E string (the first string) at the fourth fret.

Your three upper fingers should now form a tight cluster on the fourth fret. The B string (between the G and high E strings) stays open—don't play it. The low E string gets muted by the side of your index finger, which rests against it without pressing down. This takes practice to feel natural; most players accidentally let the low E ring at first.

Common Mistakes That Cause Buzzing or Dead Strings

The most frequent problem is pressing your fingertips too far back on the fret, toward the middle of the fret space rather than just behind the wire. This causes the string to buzz against the fret behind your finger. Move your fingertips closer to the fret wire—not on top of it, but as close as you can get without touching the wire itself. You should hear a clear ring, not a buzz.

The second mistake is not pressing hard enough. B7 requires real pressure because your fingers are bunched together and the strings are farther from the fretboard at higher positions. If a string sounds dead or muted, press harder. Your fingertips will hurt for the first week or two; this is normal and goes away as your skin toughens.

The third mistake is accidentally muting the B string or the high E string with the flesh of your adjacent fingers. When your middle and ring fingers sit next to each other on the fourth fret, the side of your middle finger can touch the B string and kill its ring. Angle your fingers slightly so your fingertips point more toward the headstock than straight down. This gives the open B string room to vibrate.

How to Transition Into and Out of B7

B7 connects most smoothly to E major or E minor because they share the open B and high E strings. When you switch from E to B7, your index finger moves from the first fret of the B string to the second fret of the A string, and your other three fingers move down and to the right. Practice this switch slowly: hold E for four beats, then move to B7 for four beats, then back to E. Do this ten times in a row, gradually speeding up.

B7 also works well before Emaj7 or Em7. The transition is similar—your index finger stays roughly in the same area, and your other fingers adjust slightly. Avoid switching directly to chords that require the low E string to ring (like D or A) because you'll have to reposition your entire hand. If a song requires B7 to D, pause for a beat between them while you reset your hand position.

Strumming and Muting the Low E String

Once your fingers hold the shape without pain, practice strumming only the top five strings—skip the low E string entirely. Use a downstroke across the B, G, D, A, and high E strings. This trains your hand to avoid the muted string. Many beginners accidentally strum all six strings out of habit, which creates a dull thud from the low E.

If you want to include the low E string in your strum pattern, make sure it's truly muted by the side of your index finger. Test this by strumming just the low E string while holding B7—you should hear nothing or a very quiet thud, not a clear note. If you hear a clear B note, your index finger isn't touching the string. Adjust it so the side of your finger rests lightly against the low E without pressing it down.

Practice Routine to Build Speed and Accuracy

Spend five minutes a day on B7 alone. In the first week, focus only on holding the shape cleanly for ten seconds at a time. Rest your hand, then repeat. Don't strum yet. In the second week, add slow downstrokes—one strum every two seconds. In the third week, strum once per second. By the fourth week, you should be able to hold B7 and strum it cleanly without thinking about finger placement.

Once B7 feels solid, practice switching between it and one other chord for ten minutes. Start with E major because the transition is easiest. Play E for four beats, B7 for four beats, and repeat for five minutes. Then switch to practicing B7 with a different chord. This builds muscle memory for the specific hand movements your songs require.

If your fingers hurt, stop and rest. Pain that goes away within an hour is normal; sharp pain that doesn't fade is a sign you're pressing too hard or your hand position is wrong. Adjust your grip and try again with less pressure.

Why B7 Sounds Different From Other Seventh Chords

B7 is a dominant seventh, which means it has a slightly tense, bluesy sound compared to major or minor chords. The seventh note (A natural) creates this tension. In blues music, B7 often leads back to E, which resolves the tension. This is why you hear B7 so often in 12-bar blues progressions—it sets up the return to the home chord.

If you play B7 and it sounds harsh or wrong, you're probably hearing the low E string ring through. Double-check that your index finger is muting it. B7 should sound bright and slightly edgy, not muddy or dull.

Frequently Asked Questions

Is B7 harder than Bm or B major?

B7 is actually easier than full B major because you don't need to barre your index finger across all six strings. However, B7 is harder than Bm (B minor) because Bm uses only three fingers and sits in a simpler shape. If you can play Bm cleanly, B7 will take another week or two of practice.

Can I play B7 without muting the low E string?

Technically yes, but it sounds muddy and out of place in most songs. The low E string plays an E note, which clashes with the B7 chord. Muting it is part of the correct technique. If muting feels impossible, focus on strumming only the top five strings until your hand strength improves.

My fingers keep touching the B string and killing the ring—how do I fix this?

Angle your fingers so they point slightly toward the headstock instead of straight down. This creates space between your middle finger and the B string. Also make sure your middle finger is pressing on the D string, not between strings. If it's in the right spot, the B string should have room to ring.

How long does it take to play B7 without thinking about it?

Most players need two to four weeks of daily practice before B7 feels automatic. This depends on how much you practice and whether you're already comfortable with other barre chords. If you practice thirty minutes a day, you'll likely feel confident within two weeks.

What songs use B7 that I can practice with?

B7 appears in blues standards like "Stormy Monday" and "All Blues," and in rock songs like "Pride and Joy" by Stevie Ray Vaughan. Start with straightforward 12-bar blues progressions (E, A, B7) because the chord changes are slow and predictable, giving you time to move your fingers.
