The BM/A chord is an intriguing chord that adds depth and richness to a variety of musical compositions. Whether you’re new to playing the guitar or a seasoned musician, understanding this chord will enhance your ability to create beautiful music. This guide is written in the simplest possible English to ensure that readers of all skill levels can grasp the concept of the BM/A chord and use it effectively.
What is the BM/A Chord?
The BM/A chord is a variation of the B minor chord (often written as Bm) with an A note added as a bass. Essentially, it’s a B minor chord played over an A bass note. You can think of this as combining two elements:
- BM (B minor chord): A minor chord based on the B note.
- A bass note: Playing the note A as the lowest note of the chord.
This chord is commonly used in pop, rock, and folk music and can give your music an emotional or slightly melancholic feel, depending on how it’s used.
How to Build the BM/A Chord
Let’s break down how to build this chord:
- B Minor (BM) Chord Structure:
- B minor is made up of three notes: B, D, and F#.
- These notes form the basic minor chord.
- A Bass Note:
- To turn the B minor into a BM/A, you need to add an A note as the bass.
- The A note becomes the root note, while the B minor chord is played on top of it.
In technical terms, the chord is notated as Bm/A because it’s essentially a B minor chord with an A note as the bass.
BM/A Chord on Guitar
When you play the BM/A chord on the guitar, you’re essentially combining the Bm chord shape with an open A string to form the bass note. Here’s a simple way to play this chord:
BM/A Chord Fingering on Guitar
- Index finger: Barre the 2nd fret, covering all strings.
- Middle finger: Press down on the 3rd fret of the B string (2nd string).
- Ring finger: Press down on the 4th fret of the D string (4th string).
- Open A string: The 5th string (A string) is played open, adding the A bass note.
When played properly, the BM/A chord should sound both full and harmonic, with the A bass note grounding the B minor chord’s minor qualities.
Common BM/A Guitar Variations
There are several ways to play the BM/A chord on the guitar, including:
- Simplified version: If the barre chord is difficult, you can simply play a regular B minor chord and allow the open A string to ring out naturally.
- Higher fret variations: Some advanced players choose to play the BM/A chord higher up the neck, creating a brighter tone.
Diagram for BM/A Chord
Here is the diagram for the standard version of the BM/A chord on guitar:
e|—2— B|—3— G|—4— D|—4— A|—0— E|—X—
- The “X” means the low E string should not be played.
- The open A string provides the A bass note.
Theory Behind the BM/A Chord
To fully understand the BM/A chord, it’s important to grasp the theory behind how it works:
- Minor Chord Structure: In music theory, a minor chord is built from three notes: the root (B), a minor third (D), and a perfect fifth (F#). This gives the chord its “minor” sound.
- Slash Chords: The BM/A is an example of a “slash chord.” In this case, the slash (/) indicates that a different bass note (A) is played below the B minor chord.
- Bass Inversion: This chord is called an “inversion” because the A note is not part of the traditional B minor chord. Inversions like this are used to create a smooth transition between chords or to add texture to a piece of music.
When to Use the BM/A Chord in Songs
The BM/A chord is used to add depth and emotion to a musical passage. Here are some specific situations where the BM/A chord works well:

- Folk and Rock Music: This chord is frequently used in folk music, rock ballads, and even pop music to add a rich, harmonic sound.
