The A7 Guitar chord is a fantastic addition to any guitarist’s repertoire. It offers a unique sound that sits between major and minor, lending itself to a wide array of musical genres. Beginner-friendly yet versatile, the A7 chord is easier to learn than you might think, opening up a world of musical possibilities.
While not as bright as a major chord nor as melancholic as a minor chord, the A7 possesses a distinctive character thanks to the inclusion of a sharp note, the C#. This subtle complexity allows the A7 to inject unexpected twists and a punchy feel into songs, whether played in a low or high register. Let’s explore how to play this essential chord and where you can use it.
Two Essential Ways to Play the A7 Guitar Chord
There are two primary ways to play the A7 chord on your guitar. Both are based on standard E tuning and are accessible even for guitarists just starting their chord journey.
First Position A7 Chord: The Open String Version
The first, and often easiest, form of the A7 chord utilizes open strings and a simple finger placement. To play this version, you’ll use two fingers on the second fret of the fretboard.
- Middle Finger: Place your middle finger (2nd finger) on the 2nd fret of the D string (4th string).
- Ring Finger: Place your ring finger (3rd finger) on the 2nd fret of the B string (2nd string).
- Strumming: Strum down from the A string (5th string), avoiding the low E string.
- Fingering:
- Middle finger: 2nd fret of the D string
- Ring finger: 2nd fret of the B string
This creates a comfortable and sonorous A7 chord, perfect for beginners and foundational in many songs.
Second Position A7 Chord: The Barre Chord Variation
For a higher-pitched and slightly more challenging A7 chord, you can explore the barre chord version. This form moves up the fretboard and requires a barre with your index finger.
- Index Finger Barre: Barre your index finger across all strings at the 5th fret.
- Middle Finger: Place your middle finger on the 6th fret of the G string (3rd string).
- Pinky Finger: Place your pinky finger on the 7th fret of the D string (4th string).
- Ring Finger: Place your ring finger on the 7th fret of the B string (2nd string).
- Strumming: Strum down from the D string (4th string), playing only the top four strings.
- Fingering:
- Index finger: Barre across 5th fret
- Middle finger: 6th fret of the G string
- Ring finger: 7th fret of the B string
- Pinky finger: 7th fret of the D string
This voicing of the A7 chord delivers a brighter tone due to its position higher up the neck, offering a different flavor to your playing.
Understanding the A7 Chord: Music Theory Basics
The A7 chord is a type of dominant 7th chord. Let’s briefly break down what that means in music theory terms:
- Root: The root note of the chord is A.
- Major Third: It contains a major third interval above the root (C#). This gives it some of that major chord brightness.
- Perfect Fifth: It includes a perfect fifth interval above the root (E).
- Minor Seventh: The crucial element that makes it an “A7” is the minor seventh interval above the root (G). This 7th interval is what adds the characteristic “dominant” or slightly bluesy, jazzy quality to the chord, differentiating it from a simple A major chord.
This combination of intervals creates a chord that is harmonically rich and has a tendency to resolve to a chord a perfect fourth below it, often a D chord in the key of A. This resolution is a fundamental concept in music theory and is used extensively in songwriting.
