Three Essential Ways to Play the C7 Chord on Guitar
The C7 chord builds upon the familiar C major chord by incorporating one crucial addition: the seventh note, Bb (B flat). This single note transforms the chord’s character, creating a richer, more complex sound. Seventh chords like the C7 are invaluable for adding depth and interest to your songs. They can be used as substitutes for major chords to create harmonic variation or to inject a specific mood into a piece. Experimenting with substituting a C7 for a C major chord can lead to exciting sonic discoveries and help you develop your unique guitar style.
One of the most accessible ways to learn the C7 chord is in the open position. This version of the C7 is a cornerstone for beginners, utilizing only five of the six guitar strings and producing a full, resonant tone.
To play the open position C7:
- Place your index finger on the 1st fret of the 2nd string (B string).
- Position your middle finger on the 2nd fret of the 4th string (D string).
- Place your ring finger on the 3rd fret of the 5th string (A string).
- Place your pinky finger on the 3rd fret of the 3rd string (G string).
- Avoid strumming the low E string, and strum downwards from the A string.
C7 Open Position Finger Placement:
- Middle finger: 2nd fret, D string (4th string)
- Ring finger: 3rd fret, A string (5th string)
- Pinky finger: 3rd fret, G string (3rd string)
Strum 5 strings down from the A string for the Open C7 chord.
While the open C7 position offers a robust and full sound, exploring different positions on the fretboard expands your sonic palette. The 3rd position C7 chord provides a brighter, higher-pitched alternative. Situated higher up the neck, this variation utilizes fewer strings, resulting in a thinner, more focused tone compared to the open position.
To play the C7 chord in the 3rd position:
- Place your index finger on the 3rd fret of the 3rd string (G string).
- Stretch your ring finger to the 5th fret of the 4th string (D string).
- Place your pinky finger on the 5th fret of the 2nd string (B string).
- Strum downwards from the D string.
C7 3rd Position Finger Placement:
- Index finger: 3rd fret, G string (3rd string)
- Ring finger: 5th fret, D string (4th string)
- Pinky finger: 5th fret, B string (2nd string)
Strum 3 strings down from the D string when playing the C7 chord in the 3rd position.
For a more advanced and tonally distinct C7 voicing, venture further up the fretboard to the 8th position. This variation, located higher on the neck, demands a muting technique for the A string and delivers a unique sonic character.
To play the C7 chord in the 8th position:
- Place your index finger on the 8th fret of the low E string, slightly muting the A string with the tip of your finger.
- Place your middle finger on the 8th fret of the 4th string (D string).
- Place your ring finger on the 9th fret of the 3rd string (G string).
- Strum downwards from the low E string, being careful to avoid the B and high E strings. Ensure the A string remains muted for the correct C7 sound.
C7 8th Position Finger Placement:
- Index finger: 8th fret, low E string (6th string), muting the A string
- Middle finger: 8th fret, D string (4th string)
- Ring finger: 9th fret, G string (3rd string)
Strum four strings down from the low E string while ensuring the A string is muted to correctly play the C7 chord in the 8th position.
Understanding the Music Theory Behind the C7 Chord
To truly master the C7 chord, it’s helpful to understand the music theory that underpins its distinctive sound. As mentioned earlier, the C7 chord is closely related to the C major chord. The key difference lies in the addition of the seventh note.
The C7 chord is built from four notes:
- C (Root)
- E (Major Third)
- G (Perfect Fifth)
- Bb (Dominant Seventh or minor seventh)
This Bb note, the flat seventh, is what gives the C7 its characteristic “dominant” quality. It creates a tension that strongly resolves to the tonic chord (F major in the key of C), making it a crucial chord in creating harmonic movement and resolution in music. This inherent tension is what lends the C7 chord its slightly restless, bright, and sometimes bluesy feel.
Songs That Showcase the Versatility of the C7 Chord
The C7 chord’s versatility is evident in its presence across numerous genres and iconic songs. From rock and pop to blues and country, the C7 adds its unique flavor to a vast musical landscape. Here are just a few examples of songs where the C7 chord plays a significant role:
C7 Chords in Rock Music
The Beatles, masters of innovative chord progressions, frequently employed the C7 chord to add a touch of sophistication to their pop sensibilities. “From Me to You,” an early hit, features a jaunty C7 chord played by George Harrison, contributing to the song’s upbeat and memorable sound. The C7 also appears in other Beatles classics like “Taxman,” “If You Believe,” and “Something,” demonstrating its subtle yet impactful presence in their songwriting.
C7 Chords in Pop Music
The slightly yearning and unresolved quality of the C7 chord makes it perfect for expressing emotional nuance in pop music. Two classic examples are “Baby Love” by The Supremes and “All By Myself” by Eric Carmen. In “Baby Love,” the C7 chord subtly underscores the questioning and uncertain nature of a relationship, while in “All By Myself,” it amplifies the feeling of loneliness and longing.
However, the C7 isn’t limited to melancholic moods. Its brighter side shines through in “Bare Necessities” from Disney’s The Jungle Book. This cheerful song, sung by Baloo the Bear, is propelled by a series of dominant 7th chords, including C7, G7, A7, E7, and D7, creating its joyful and carefree atmosphere.
Another iconic example is “When the Saints Go Marching In,” a song that transcends genres, blending gospel, pop, and jazz influences. The C7 chord is integral to its New Orleans-inspired sound, giving the song its characteristic punch and vibrancy, especially when combined with bass note strumming.
C7 Chords in Blues Music
The inherent bluesy character of the C7 chord makes it a natural fit for the blues genre. Reverend Gary Davis masterfully utilizes the C7 in his “Hesitation Blues,” showcasing its ability to create that quintessential bluesy tension. Buddy Guy, in “Let Me Love You Baby,” also employs the C7 to add a touch of romantic pleading to his blues classic. This song, a blues standard, has been covered by guitar legends like Stevie Ray Vaughan and Jeff Beck, further solidifying the C7’s place in blues music.
C7 Chords in Country Music
The C7 chord’s adaptability extends to country music, where it has been embraced by some of the genre’s most influential artists. Hank Williams, a foundational figure in country music, incorporated the C7 chord into his hit “Hey Good Lookin’.” Alongside other 7th chords (G7 and D7) and major chords (C and F), the C7 contributes to the song’s timeless and widely covered sound.
Conway Twitty, another country icon, used the C7 chord in his poignant ballad “Hello Darlin’.” The C7 adds a subtle unease to the song’s narrative of encountering a past love, enhancing the emotional depth of this signature tune that Twitty often used to open his concerts.
