Standard 7-String Tuning
The String Configuration: In standard 7-string tuning, the strings are tuned from the thinnest to the thickest as B, E, A, D, G, B, E. The thinnest string, tuned to B, extends the upper range of the guitar, allowing for more intricate lead playing and access to higher notes that might be difficult to reach on a 6-string. For example, in a fast-paced solo, this high B string can add a sense of brightness and clarity. The remaining strings follow the same tuning pattern as the lower five strings of a 6-string guitar, providing a familiar foundation for chord formation and rhythm playing.
Benefits of Standard Tuning: This tuning is widely used because it offers a good balance between the extended range and the ease of transitioning from 6-string playing. Many guitarists who are accustomed to 6-string techniques can quickly adapt to the 7-string in standard tuning. It also allows for a seamless integration of 7-string playing in various musical genres such as rock, metal, and jazz. For instance, in a metal song, the lower B string can produce a powerful and deep bass note, enhancing the overall heaviness of the sound.
Drop Tunings for 7-String Guitars
Drop A Tuning: One popular drop tuning for 7-string guitars is Drop A, where the strings are tuned A, E, A, D, G, B, E. By dropping the thinnest string from B to A, a much lower and heavier sound is achieved. This tuning is favored in heavy metal and hard rock genres, where a thick and crushing tone is desired. For example, in a djent style of music, the low A string can be used to create complex and palm-muted rhythms that drive the music forward. The other strings remain in a similar tuning to standard 6-string drop tunings, making it relatively easy for guitarists familiar with those tunings to adapt.
Drop G Tuning: Drop G tuning, with the strings tuned G, D, G, C, F, A, D, takes the low end even further. This tuning is excellent for creating a sludgy and slow-paced sound, often used in doom metal and some ambient music. The extremely low G string can produce a rumbling effect that adds a sense of weight and darkness to the music. For instance, in a doom metal riff, the guitarist can use the low G string to establish a slow and menacing groove, while the other strings provide harmonic and melodic support.
Open Tunings on 7-String Guitars
Open G Tuning: In 7-string open G tuning, the strings are typically tuned D, G, D, G, B, D, G. This tuning allows for the creation of rich and resonant chord voicings by simply strumming the open strings. It is popular in blues, folk, and some forms of rock music. For example, in a blues song, the open G tuning can produce a warm and full-bodied sound, and the guitarist can easily slide between chords and add embellishments. The additional string in 7-string open G tuning gives more options for creating complex chord shapes and unique melodic lines within the open tuning framework.Open D Tuning: Open D tuning for 7-string guitars is often tuned D, A, D, F#, A, D, A. This tuning is known for its bright and harmonious sound. It is frequently used in fingerstyle and acoustic music. The open strings create a natural and beautiful chord, and the guitarist can use the extra string to add bass notes or higher harmonics. For instance, in a fingerstyle piece, the guitarist can pluck the lower D string to establish a solid foundation while playing intricate melodies on the upper strings.
Tuning for Specific Genres
Jazz Tuning Considerations: In jazz, 7-string guitars may be tuned in a way that emphasizes chord voicings and extended harmony. While standard tuning is often used, some jazz guitarists might make slight adjustments. For example, they might raise or lower a string by a half step to better fit a particular chord progression or to achieve a more unique sound. The additional string can be used to add extra notes to chords, such as 9ths, 11ths, or 13ths, enhancing the harmonic complexity of the music.
Classical and Fingerstyle Tuning: For classical and fingerstyle playing on 7-string guitars, the tuning might be adjusted to optimize the instrument’s resonance and playability for complex fingerpicking patterns. Some players might use a tuning similar to standard but with a different string gauge combination to achieve a more balanced tone across all the strings. The extra string can be used to add a lower bass note or a higher harmonic, depending on the musical passage. For instance, in a classical piece, the guitarist can use the lowest string to create a deep and sonorous bass line, while the upper strings handle the melody and accompaniment.
Tuning Tools and Techniques
Electronic Tuners: Electronic tuners are a convenient and accurate way to tune 7-string guitars. They can detect the pitch of each string and display whether it is sharp or flat. Many modern tuners have specific settings for 7-string guitars, making the tuning process straightforward. For example, a guitarist can simply pluck each string and adjust the tuning peg until the tuner shows the correct pitch. Some clip-on tuners can be attached to the headstock of the guitar, allowing for easy tuning even in a live performance setting.
Tuning by Ear: Tuning by ear is a valuable skill for any guitarist. To tune a 7-string guitar by ear, one can start with a reference pitch, such as an A from a tuning fork or another tuned instrument. Then, use the fretboard to find the correct pitches for the other strings. For example, the fifth fret of the A string should match the open D string. By comparing the pitches of the strings and making adjustments, a guitarist can achieve accurate tuning. This method requires practice and a good sense of pitch, but it can be very useful in situations where an electronic tuner is not available.
