The B major chord is built from a root note (A), a major third (C), and a perfect fifth (E):
- Type: major triad.
- Formule: 1 3 5.
- Music notes: B (1) D# (3) F# (5).
- Chords to play with: IV (E) y V (F#).
B chord [Musical explanation]
The B major chord is a major triad with formula 1 – 3 – 5. Therefore, to build it we need B (1), D# (3), F# (5):
This is due to the fact that a major chord is made up of 2 third intervals:
- A major interval (4 half steps between the 3rd and root).
- A minor inteval (3 half steps between the 5th and 3rd).
If we apply this principle to the B chord we obtain that:
- D# is the major third of B because it is 4 half steps above the root.
- F# is the perfect fifth of B because it is 3 half steps above the 3rd.
Thus, this confirms that the B major chord is defined by:
Root (B) – Major Third (D#) – Perfect Fifth (F#)
B Guitar Chord
The B major chord guitar has the following shape on the fretboard:
Let’s analyze in detail this chord diagram above to make sure that we understand how to play the B on guitar:
Let’s start by analyzing the 3 circles in blue, which indicate that on the strings 4 (D), 3 (G) and 2 (B) we have to place the fingers 2 (middle), 3 (ring finger) and 4 (pinky). In this case we need to play a barre chord, so we have to use as well the index finger (1) to press down the strings from 5 to 1.
Note by the way the number 2 in black on the left that indicates on which fret we start playing the chord.
On the other hand, at the top we see that we have the characters:
X B F# B D# F#
This simply means that in the:
- Sixth string there is no sound.
- Fifth string sounds the B note.
- Fourth string sounds the F# note.
- Third string sounds the B note.
- Second string sounds the D# note.
- First string sounds the F# note.
And at the bottom we find the numbers:
1 5 1 3 5
This indicates that in the:
- Sixth string There is no number because there is no sound.
- Fifth string sounds the root (1).
- Fourth string sounds the perfect fifth (5).
- Third string sounds the root (1).
- Second string sounds the major third (3).
- First string sounds the perfect fifth (5).
⚠️ Important: it is not mandatory to memorize all this information to play the B chord on guitar. But it is highly recommended to know it in order to understand the musical theory behind each chord.
