Drop B Tuning Chords: Verified Shapes and Voicings
Drop B tunes a six-string guitar to B1 F#2 B2 E3 G#3 C#4, low to high — 61.74, 92.50, 123.47, 164.81, 207.65, and 277.18 Hz at A4 = 440 Hz. Two things follow from those six notes. The bottom three strings already spell a B5 power chord, and because the low B sits a perfect fifth below the F# string, fretting strings 6, 5, and 4 at the same fret sounds root, fifth, and octave under one finger. Everything else behaves like standard tuning moved down three semitones: a shape you already play on strings 5 through 1 keeps its fingering and its chord quality, but its name drops a minor third, so an A shape sounds F# and an Am shape sounds F#m. Shapes that touch the sixth string are the ones that have to be rebuilt, and every chart below lists the note each string actually sounds so you can check a voicing one string at a time.
This page is a static chord reference. It does not listen to your instrument and it does not play any audio.
The six open strings in drop B
Read the fifth column first. Five of the six strings drop exactly three semitones from standard tuning, and the sixth drops five. That single difference is the whole reason drop B chord shapes behave the way they do.
| String | Open note | Frequency at A4 = 440 Hz | Standard tuning | Change from standard |
|---|---|---|---|---|
| 6th (lowest) | B1 | 61.74 Hz | E2 | down 5 semitones |
| 5th | F#2 | 92.50 Hz | A2 | down 3 semitones |
| 4th | B2 | 123.47 Hz | D3 | down 3 semitones |
| 3rd | E3 | 164.81 Hz | G3 | down 3 semitones |
| 2nd | G#3 | 207.65 Hz | B3 | down 3 semitones |
| 1st (highest) | C#4 | 277.18 Hz | E4 | down 3 semitones |
Targets are in 12-tone equal temperament at A4 = 440 Hz, rounded to two decimals. Only A4 is fixed by convention, and ISO 16:1975 specifies 440 Hz for it:ISO 16:1975, Acoustics — Standard tuning frequency (Standard musical pitch).
How drop B moves your shapes
Three rules cover every shape on this page. They follow from the interval layout of the tuning.
Rule 1 — strings 5 through 1 keep the standard layout. From the 5th string to the 1st, drop B uses the same intervals as standard tuning: a fourth, a fourth, a major third, then a fourth. Every shape you already play on those five strings keeps its fingering and its chord quality, but it sounds three semitones lower, so its name drops a minor third. A shape that spells A in standard tuning spells F# here; Am spells F#m.
Rule 2 — the 6th string changes the bass. In standard tuning the 6th string is a fourth below the 5th; in drop B it is a perfect fifth below. That is what makes strings 6, 5, and 4 at one fret a complete power chord — root, fifth, and octave — and why a sixth-string-root shape has to be rebuilt rather than renamed.
Rule 3 — drop B is drop D, three semitones lower on every string. Drop D is D2 A2 D3 G3 B3 E4; move all six strings down three semitones and you land exactly on B1 F#2 B2 E3 G#3 C#4. Every drop D grip transfers with the same fingers and a new name — the drop D chord guide on this site is the chart to compare against as you carry those same fingers and frets across.
Which shape to reach for
Find what you are trying to play, then use the shape family in the second column.
| What you are trying to play | Reach for | Why it works in B F# B E G# C# |
|---|---|---|
| A riff or power chord with the low root | Strings 6, 5, and 4 barred at the root's fret | The 6th string is a perfect fifth below the 5th, so those three strings at one fret are root, fifth, and octave |
| A major, minor, or seventh chord with the root on the 6th string | The drop D open family moved to the fret that names your root | The shape assumes a fifth between the 6th and 5th strings, which is exactly what drop B gives |
| A chord with the root on the 5th string | Any standard shape, unmoved | Strings 5 through 1 keep the standard fourth–fourth–third–fourth layout |
| A shape you already know in standard tuning | Play it as written, then rename it a minor third lower | Strings 5 through 1 sit three semitones below standard |
| A shape you learned in drop D | Keep the same fret numbers — the identical grip sounds three semitones lower; move it up three frets only if you must hold the original sounding pitch | Drop B is drop D three semitones lower on all six strings, so the same frets sound lower and the original sounding pitch sits three frets higher |
| A standard-tuning barre with the root on the 6th string, such as the E shape 0-2-2-1-0-0 | Do not use it as written — rebuild it with the drop D family | The 6th string moved five semitones while strings 5 through 1 moved three, so the shape's intervals no longer line up |
The last row is the mistake that makes copied shapes sound wrong. Played as written in drop B, 0-2-2-1-0-0 sounds B1, G#2, C#3, F3, G#3, and C#4 — B, G#, C#, F. That is not a B chord. The shape has to change, because the string it is rooted on moved two semitones further than the strings above it.

Frets run 6th string to 1st, with x for a string you do not play. The note column lists what each string actually sounds, so any row can be checked one string at a time. This section prints on its own.

Every row is arithmetic from the open strings above: the fretted note is that string's open note plus one semitone per fret. Print this section for a paper copy.
Same grip, new name
Every grip below is a shape players already know from drop D. The last three columns show what it is called there, what it is called here, and what those frets actually sound.

Nothing about the fingers changes; only the name does, by a minor third every time. Moving a song from drop D to drop B is that one move: the shapes stay and the frets stay, and the chord symbols come down three semitones. Keep the same fret numbers, because the grip simply sounds three semitones lower; move a shape up three frets only when you must hold the original sounding pitch.
How to check a voicing yourself
The chart is only useful if you can audit it. This procedure works for any shape on the page.
- Tune the six open strings to B1, F#2, B2, E3, G#3, and C#4. Everything here assumes those targets.
- Pick a row and read its fret column. Each digit is a fret number, starting at the 6th string; x means that string is not played.
- On the 6th string, count up from B1 one semitone per fret: fret 2 is C#2, fret 5 is E2, fret 7 is F#2, fret 10 is A2.
- Do the same on every other string from its own open note, not from the 6th string's note. Every string has its own starting point.
- Compare what you counted with the note column. If a note there is not in the chord you intended, the shape spells something else.
- Check the octave at the 12th fret: its harmonic is the same note name one octave up, which confirms which octave the shape sits in.
One worked row, so the method is concrete. Take E, 5-5-5-4-3-3. From B1, fret 5 is E2. From F#2, fret 5 is B2. From B2, fret 5 is E3. From E3, fret 4 is G#3. From G#3, fret 3 is B3. From C#4, fret 3 is E4. That is E, B, E, G#, B, E — an E major chord with its root in three octaves. The tuning frequency chart on this site runs the same arithmetic on standard tuning.
What this page cannot tell you
- It does not listen to your instrument. There is no microphone here and no audio playback. Every note is arithmetic on the open-string targets, not a measurement of your guitar.
- Six-string guitar only. On a four-string bass the notes are different; the drop B bass reference covers that instrument.
- These are shapes, not a full chord vocabulary. The 23 voicings listed are low-position or common barre shapes. Inversions, extensions, and shapes above the 12th fret are not covered.
- Drop B is not open C. Its open strings spell a power chord, not a full triad, so you get one-finger low chords rather than a whole open major chord. The open C chord shapes reference is the contrasting case.
- Looser strings are part of the deal. At a given gauge and scale length, tension is proportional to the square of the frequency, so three semitones down is about 71 percent of the original tension and five semitones down about 56 percent. Expect a looser feel if you stay in drop B.
- Setup work is not covered here. Relief, truss-rod, nut, and saddle adjustment belong to your instrument's maker or a qualified guitar tech; follow the maker's official manual.
- A correct shape can still sound wrong. If every string reads in tune and the chord is still sour, that is usually intonation rather than the shape; the intonation and setup checks on this site cover what to look at.
- A low string that keeps dropping. If the 6th string reaches B1 and drifts flat within minutes, work through the restringing and tuning-stability checklist, then the setup-order walkthrough, before you blame the shape.

Frequently asked questions
Drop B is B1, F#2, B2, E3, G#3, and C#4, from the 6th string to the 1st. At A4 = 440 Hz those targets are 61.74, 92.50, 123.47, 164.81, 207.65, and 277.18 Hz. The bottom three strings — B, F#, B — already spell a B5 power chord on their own.
Yes, with different names. Drop B sits exactly three semitones below drop D on all six strings, so every drop D grip transfers with the same fingers and a name a minor third lower. The grip 0-0-0-2-3-2 is D in drop D and B here; 0-0-0-2-3-1 is Dm there and Bm here.
Because the 6th string moved further than the others. Drop B lowers strings 5 through 1 by three semitones but the 6th string by five, so a shape rooted on the 6th string no longer lines up. The standard E-shape barre 0-2-2-1-0-0 sounds B, G#, C#, F here, which is not a B chord. Shapes on strings 5 through 1 keep working; sixth-string shapes need the drop D family.
Six targets, then the shapes
Get the open strings to B1 F#2 B2 E3 G#3 C#4 first, then pick a row from the chart and check it one string at a time.
