The B suspended 4th chord: notes, intervals and inversions
A suspended 4th chord is built from root + perfect fourth + perfect fifth: a stack of a perfect fourth (5 semitones) and a major second (2), each placed on top of the one before. On B that gives B, E and F♯. Each chord tone gets its own letter name (root B, fourth E, fifth F), so the spelling is fixed by the rule, not by taste. Spelling rule: the fourth is written with the letter E (three letters above B) and the fifth with the letter F (four letters above B), which is why the chord contains F♯ and not G♭.
Pitch-class numbers (C = 0): 11, 4, 6. The same three pitch classes sound in every octave and in every inversion.
| Chord tone | Note | Interval above the root | Semitones | On the keyboard |
|---|---|---|---|---|
| Root | B | unison | 0 | white key |
| Fourth | E | perfect fourth | 5 | white key |
| Fifth | F♯ | perfect fifth | 7 | black key |
B suspended 4th on the staff: root position and both inversions
Treble clef. The notes are the same three each time; only the lowest one changes. Drawn in your browser (VexFlow); the notes are also written out under each staff.
B – E – F♯
E – F♯ – B
F♯ – B – E
An inversion puts another chord tone in the bass. The chord symbol with a slash names the bass note; the last column gives the letter-name distance of each other note above the bass (3 = a third, 5 = a fifth, 7 = a seventh ...).
| Position | Notes, bottom to top | Bass note | Chord symbol | Intervals above the bass |
|---|---|---|---|---|
| Root position | B – E – F♯ | B | Bsus4 | 5/4 |
| First inversion | E – F♯ – B | E | Bsus4/E | 5/2 |
| Second inversion | F♯ – B – E | F♯ | Bsus4/F♯ | 7/4 |
Bsus4 on guitar: 4 fingerings
The database lists 4 fingerings for Bsus4 on the guitar: 4 barre shapes. Strings are drawn left to right in the order E A D G B E (standard tuning, lowest string first). A number inside a dot is the finger (1 = index, 4 = little finger); × marks a string you do not play, ○ an open string, and a bar across the strings is a barre (one finger pressing several strings at the same fret). The letters under each diagram are the note each string sounds, spelled as in the chord (B, E, F♯).
1 of the 4 shapes has the root in the bass; the other 3 have the fourth or the fifth in the bass (a slash chord such as Bsus4/F♯).

Bsus4 on ukulele: 4 fingerings
The database lists 4 fingerings for Bsus4 on the ukulele: 2 barre shapes and 2 closed shapes. Strings are drawn left to right in the order G C E A (standard tuning; the G string is tuned high, so the strings do not run from low to high). A number inside a dot is the finger (1 = index, 4 = little finger); × marks a string you do not play, ○ an open string, and a bar across the strings is a barre (one finger pressing several strings at the same fret). The letters under each diagram are the note each string sounds, spelled as in the chord (B, E, F♯).
None of the 4 shapes has the root in the bass; all have the fourth or the fifth in the bass (a slash chord such as Bsus4/E and Bsus4/F♯).

Bsus4 on the piano keyboard
Press the three keys B, E, F♯ together. The pictures show the same chord in root position and both inversions, using the voicings of the staves above; the brass keys are the chord tones and the darker one is the root. The chords-db piano entry for Bsus4 lists the same three pitch classes, which the build script compared with the notes above.
B – E – F♯
E – F♯ – B
F♯ – B – E
Key numbers count the 88 keys of a full piano from the lowest A (key 1); middle C is key 40.
| Chord tone | Note | Key colour | Key number (1–88) |
|---|---|---|---|
| Root | B | white | 39 |
| Fourth | E | white | 44 |
| Fifth | F♯ | black | 46 |
Which keys contain the B suspended 4th chord?
The script builds this chord type on every degree of the 24 keys of this site (the scales on the key pages) and keeps the chords whose three pitch classes equal Bsus4. Result: 10 of the 24 keys contain it among their own chords, and 3 more borrow it from the parallel minor key.
The same chord can be spelled differently in different keys, because the notes must follow each key's scale: B suspended 4th as C♭sus4 in A♭ major; B suspended 4th as C♭sus4 in D♭ major.
| Key | Role (Roman numeral) | Written in that key as | How it gets there | Songs in the key (Lieder) | Scores in the key (Mutopia) |
|---|---|---|---|---|---|
| G major | IIIsus4 | Bsus4 | in the key | 118 | 287 |
| D major | VIsus4 | Bsus4 | in the key | 99 | 195 |
| A major | IIsus4 | Bsus4 | in the key | 74 | 120 |
| E major | Vsus4 | Bsus4 | in the key | 91 | 63 |
| B major | Isus4 | Bsus4 | in the key | 40 | 8 |
| F♯ major | IVsus4 | Bsus4 | borrowed from the parallel minor | 27 | 14 |
| D♭ major | ♭VIIsus4 | C♭sus4 | borrowed from the parallel minor | 49 | 16 |
| A♭ major | ♭IIIsus4 | C♭sus4 | borrowed from the parallel minor | 86 | 38 |
The two song columns are the number of OpenScore Lieder songs (of 1,462) and of Mutopia scores whose home key is the key in that row, taken from the key pages. They show how much music is written in the key where the chord lives, not how often the chord itself sounds; that is the next section. In the Lieder the major or minor mode is an estimate, the key signature is exact.
Chords easily confused with Bsus4
Chords of this library whose pitch classes are exactly those of Bsus4. The notes are the same on a keyboard; the name depends on which note is heard as the root, and the spelling follows the key.
| Chord | Its notes | What differs |
|---|---|---|

Found by comparing the pitch classes of all 168 chords in this library. Sharing two notes is why such chords can stand in for each other in a progression; a chord changes mood or function through the one note that differs.
| Chord | Its notes | Shared with Bsus4 | The one note that differs | Root relation |
|---|---|---|---|---|
| B major | B – D♯ – F♯ | B and F♯ | E here, D♯ there | same root (parallel chord) |

Enharmonic name. B suspended 4th sounds the same as C♭ suspended 4th (C♭ – F♭ – G♭) on a keyboard. Both spellings are used in practice: choose the one that fits the key of the piece.
Background from Wikipedia: suspended 4th chords, chords and inversion
Suspended chord
A suspended chord (or sus chord) is a musical chord in which the third is replaced by a dissonant tone like a perfect fourth or a major second. The resulting sound is tonally ambiguous. The practice is widespread in popular music.

Chord
A chord is the simultaneous sound of two or more musical notes. The most common chord has three notes and is known as a triad. Added tone chords, extended chords, and tone clusters can have more than three notes and are common in contemporary classical music and jazz.
An arpeggio is a chord where notes are sounded separately. A series of chords is sometimes called a chord progression. There are several ways to notate chords including figured bass, Roman numerals, the Nashville Number System, and alphabetical chord notation.

Inversion: root position and inverted chords
Root position and inverted chords
A chord is in root position if its root is the lowest note. This is sometimes known as the parent chord of its inversions. For example, the root of a C-major triad is C, so a C-major triad will be in root position if C is the lowest note and its third and fifth (E and G, respectively) are above it – or, on occasion, do not sound at all.
In an inverted chord, the root is not the lowest note. The inversions are numbered in the order their lowest notes appear in a close root-position chord (from bottom to top).
- In the first inversion, the lowest note is E – the third of the triad – with the fifth and the root stacked above it (the root now shifted an octave higher), forming the intervals of a minor third and a minor sixth above the inverted bass of E, respectively.
- In the second inversion, the lowest note is G – the fifth of the triad – with the root and the third above it (both again shifted an octave higher), forming a fourth and a sixth above the (inverted) bass of G, respectively.

How this page was made
- Note names. Computed from the root and the interval pattern with the rule “one letter name per chord tone” (the same code that spells the scales on the key pages), then checked: letters, semitone pattern, no double accidentals.
- Fingerings. Every position comes from chords-db; the script recomputes the sounding pitch of each string in standard tuning and stops the build unless all of them are notes of this chord.
- Roles in keys. The chord type is built on every degree of the 24 key scales used on the key pages; a chord counts when its pitch classes equal this chord's.
- Statistics. No chord-use statistic is given for this chord type: the Lieder analysis labels chords by Roman numeral and does not separate it. Counts of songs per key come from the key pages.
- Independent check. A separate test (tests/chordlib/verify-tonal.test.mjs) re-derives the notes of every page with the tonal library and compares notes, staff voicings, keyboard voicings and every fingering.

What this page cannot tell you
- The fingerings are one community-maintained database's choices; many other fingerings exist, and a good player will voice the chord to suit the music.
- Chord labels in the Lieder are software output that nobody has checked, for 19th-century art songs. Percentages show the repertoire, not pop or jazz.
- Sevenths and inversions are folded into the plain chord in the Lieder statistics, so they cannot tell a root-position triad from a first inversion.
- Roles in keys are counted for the 24 keys on this site and for major, natural and harmonic minor only; other scales (melodic minor, modes) are not searched, and only the third, fourth, sixth and seventh degrees of the parallel minor are borrowed.
Checks run each time this page is rebuilt
