The 8-string guitar has emerged as a fascinating instrument in the world of music, offering guitarists a broader sonic palette to explore. Originating from the traditional 6-string guitar, the addition of two extra strings has opened up new possibilities for musical expression. This innovation can be traced back to the evolving needs of musicians who desired to expand the lower register of the guitar, much like the way the bass guitar extended the low-end capabilities in a band setup.
The 8-string guitar, with its extended range, has found its place in various music genres. In metal music, for example, the lower strings are used to produce deep, heavy riffs that add a layer of aggression and power to the sound. Progressive rock and jazz fusion guitarists also utilize the extra strings to create complex chord voicings and explore unique melodic ideas that are not possible on a standard 6-string guitar.
As we delve into the world of 8-string guitar tuning, it’s important to understand the significance of proper tuning. Just like a well-tuned engine in a car ensures smooth performance, a properly tuned 8-string guitar guarantees that the notes sound clear, harmonious, and in tune with each other. This not only enhances the overall musical experience for the listener but also makes it easier for the guitarist to play complex passages and create beautiful music. So, let’s explore the different aspects of tuning an 8-string guitar.
Standard Tuning on an 8-String Guitar
The standard tuning on an 8-string guitar is an extension of the standard tuning on a 6-string guitar. On a 6-string guitar, the standard tuning from the lowest to the highest string is E – A – D – G – B – E. The 8-string guitar adds two lower strings to this setup. The seventh string is tuned to B, which is a fourth lower than the lowest E string on a 6-string guitar. The eighth string, the lowest on the 8-string guitar, is tuned to F#. So, in total, the standard tuning on an 8-string guitar is F#-B-E-A-D -G-B-E.
This tuning allows guitarists to access a wider range of low notes. For instance, in a musical composition where a deep, resonant bassline is required, the lowest F# and B strings can be used to create that foundation. In metal music, the lower strings are often used to play power chords an octave lower than what is possible on a 6-string guitar, adding a heavier and more aggressive sound.
Popular Alternate Tunings
Drop Tunings
Drop tunings are quite popular among 8-string guitarists. In a drop tuning, one or more of the strings are tuned down to a lower note. For example, in Drop A on an 8-string guitar, the lowest F# string is tuned down to A. This tuning is great for creating a very heavy, thick sound. Guitarists can play power chords using the lower strings that have a more pronounced and aggressive tone. It’s often used in sub-genres of metal like death metal and doom metal, where the low, heavy sound is a characteristic element of the music.
Open Tunings
Open tunings are another type of alternate tuning. In an open tuning, the strings are tuned so that when all are strummed open, a chord is produced. For an 8-string guitar, an open D tuning could be something like D-A-D-F#-A-D-F#-A. This tuning allows for easy slide guitar playing as well as creating unique, resonant chord voicings. In blues and folk music, open tunings are often used to create a more open and resonant sound, and the 8-string guitar in open tuning can take this to a new level with its extended range.
Choosing the Right Strings for Tuning
When tuning an 8-string guitar, choosing the right strings is crucial. Since the 8-string guitar has an extended range, the strings need to be able to handle the tension and produce a good sound. The scale length of the 8-string guitar, which can vary between 27 inches (686 mm) and 29.5 inches (750 mm), plays a role in string selection. Longer scale lengths generally require heavier gauge strings to maintain proper tension.
If the scale length of your 8-string guitar is on the longer side, say around 29 inches, you might need to choose a set of strings with a heavier gauge for the lower strings, like the F# and B strings. Heavier gauge strings can produce a more robust and full-bodied sound, which is ideal for the lower register of the 8-string guitar. On the other hand, if your guitar has a shorter scale length, lighter gauge strings might be more suitable as they will be easier to play and still produce a clear sound.
It’s also important to consider the type of music you play. If you’re into heavy metal, you might prefer strings that can withstand high tension and produce a thick, aggressive sound. For more delicate genres like jazz or classical, strings that produce a warmer, more nuanced sound might be a better choice.
Tools for Tuning an 8-String Guitar
Electronic Tuners
Electronic tuners are one of the most common and accurate tools for tuning an 8-string guitar. There are different types of electronic tuners available. Clip-on tuners are very convenient as they can be attached directly to the headstock of the guitar. They work by detecting the vibrations of the strings, which is useful in noisy environments where a microphone-based tuner might pick up unwanted background noise.
Pedal tuners are another option, especially for guitarists who perform live. They can be easily incorporated into a pedalboard setup. When using an electronic tuner, you simply select the appropriate tuning mode (most tuners have presets for standard 8-string tuning). Then, you pluck each string one by one, and the tuner will display whether the string is in tune, sharp (higher in pitch than the desired note), or flat (lower in pitch than the desired note). You adjust the tuning of the string using the tuning pegs until the tuner indicates that the string is in tune.
Tuning Apps
In the digital age, tuning apps have become a popular alternative to traditional tuners. There are many tuning apps available for smartphones and tablets. These apps use the device’s microphone to pick up the sound of the guitar strings. They are often very user-friendly, with clear visual displays showing the name of the note and whether it’s in tune. Some apps even offer additional features like the ability to save custom tunings, which is very useful for 8-string guitarists who might use a variety of alternate tunings.
Chromatic Tuners
Chromatic tuners are a type of electronic tuner that can detect any musical note, not just the standard guitar notes. This is useful for 8-string guitarists who might be using alternate tunings with non-standard notes. A chromatic tuner can accurately identify the pitch of any string on the 8-string guitar, whether it’s tuned to a note in the standard tuning or an alternate tuning. It provides a more versatile tuning solution for guitarists who like to experiment with different tunings.
Conclusion
In conclusion, tuning an 8-string guitar is a multifaceted process that combines art and science. From understanding the nuances of standard and alternate tunings to carefully selecting the right strings and using appropriate tuning tools, every step plays a vital role. The standard tuning provides a solid base, while alternate tunings like drop and open tunings offer unique sonic landscapes for different musical genres. Choosing the correct strings according to scale length and musical style, along with employing reliable tuning devices such as electronic tuners, apps, or chromatic tuners, ensures accurate tuning. The step-by-step tuning process, from preparing the guitar to maintaining tuning stability through high – quality pegs, humidity control, and regular checks, guarantees that your 8-string guitar remains a source of beautiful, harmonious music. With these techniques in hand, guitarists can fully unlock the potential of this extraordinary instrument and create music that resonates deeply with audiences.
