Introduction
Learning to play the guitar can be an exciting journey, but it can also be overwhelming. As you progress, you’ll encounter a variety of chords, each with its own unique sound and finger positioning. One of the chords that often confuses guitarists, especially beginners, is the BM/A chord. This chord is not just a simple major or minor chord; it’s a bit more complex and brings a distinct flavor to the music.
In this article, we’ll dive deep into the BM/A chord, explaining what it is, how to play it, and how to incorporate it into your music. We’ll also explore its theory, variations, and common uses in different genres. By the end of this guide, you’ll have a solid understanding of the BM/A chord and be able to use it confidently in your guitar playing.
What is the BM/A Chord?
Breaking Down the BM/A Chord
The BM/A chord is known as a “slash chord” or “compound chord.” This means it combines two different chords into one. Specifically, the BM/A chord is a B minor chord with an A as the bass note.
- B Minor (BM) Chord: The B minor chord is made up of three notes: B, D, and F#. It’s a minor chord, which gives it a sad or melancholic sound.
- A (Bass) Note: In the BM/A chord, the bass note is A. This means that instead of playing the B note as the lowest pitch in the chord, you play the A note.
When these elements are combined, the BM/A chord has a richer, more complex sound compared to a standard B minor chord.
Music Theory Behind BM/A
To understand the BM/A chord fully, it’s helpful to dive into a bit of music theory. The B minor chord is built on the root (B), minor third (D), and perfect fifth (F#). When we add an A note as the bass, it changes the overall sound and function of the chord. This new note (A) is the 7th degree of the B minor scale, and when placed in the bass, it creates a tension that resolves nicely to other chords.
The chord symbol BM/A indicates that you should play a B minor chord with an A in the bass, resulting in a B minor 7th chord in first inversion. This inversion can create a sense of movement in the harmony, leading smoothly to other chords in a progression.
How to Play the BM/A Chord on Guitar
Finger Placement
Playing the BM/A chord on the guitar can be a bit challenging at first, especially if you’re new to slash chords or fingerstyle playing. Here’s a step-by-step guide to help you master it:
- Index Finger (1st Finger): Place your index finger across all six strings on the 2nd fret, barring them. This is known as a “barre” and forms the foundation for many chords, including BM.
- Middle Finger (2nd Finger): Place your middle finger on the 3rd fret of the B string (2nd string from the bottom).
- Ring Finger (3rd Finger): Place your ring finger on the 4th fret of the D string (4th string from the bottom).
- Little Finger (4th Finger): Place your pinky finger on the 4th fret of the G string (3rd string from the bottom).
- Play the A (Open String): For the A bass note, you need to play the open A string (5th string from the bottom).
When strumming, make sure you avoid hitting the low E string (6th string). Focus on strumming from the A string downward.
Common Mistakes to Avoid
- Inadequate Pressure: Applying insufficient pressure with your index finger when barring can cause the chord to sound muted or buzzy. Ensure you press down hard enough to get a clear sound.
- Incorrect Finger Positioning: Make sure your fingers are positioned just behind the frets, not on top of them, to avoid buzzing.
- Overstrumming: Avoid strumming the low E string, as it doesn’t belong in the BM/A chord and can muddy the sound.
Practice Tips
- Start Slowly: Begin by practicing the chord slowly, ensuring each note rings out clearly.
- Use a Metronome: Gradually increase your speed with a metronome as you become more comfortable.
- Chord Transitions: Practice moving from the BM/A chord to other chords in common progressions, like G, D, or A.
Variations and Voicings of the BM/A Chord
Exploring Different Voicings
The BM/A chord can be played in different positions on the guitar neck, offering various voicings that can add diversity to your playing. Here are a few common variations:
- Open Position BM/A: Instead of barring, you can play a simpler version using open strings. For instance, place your index finger on the 2nd fret of the G string and strum from the A string downward, leaving the other strings open.
- Higher Octave BM/A: Move the chord shape up the neck to create a higher-pitched version of the BM/A chord. For example, you can play it starting from the 7th fret.
- Fingerstyle BM/A: Incorporate fingerpicking to emphasize the A bass note while gently playing the higher B, D, and F# notes.
Using a Capo
A capo can also be used to create different voicings of the BM/A chord without changing the key of the song. For instance, place the capo on the 2nd fret and use an Am chord shape to create a BM/A sound.
Power Chords and Simplified Versions
If you find the BM/A chord too difficult, you can start with a power chord version, which simplifies the chord to just the B and F# notes with the A bass. This version is often used in rock and pop music to give a more aggressive sound.
