Extended Range Guitars (ERGs) have opened up new sonic territories for guitarists, with 9 String Guitars representing the deeper end of this spectrum. For players venturing into these lower registers, one of the first considerations is tuning. How do you approach tuning a 9 string guitar to maximize its potential and playability?
One popular and arguably intuitive method for tuning a 9 string guitar is to extend the standard tuning downwards. Starting with the familiar E standard (EADGBE), you simply add lower strings in fourth intervals. This approach results in a tuning of G#0-C#1-F#1-B1-EADGBE. The beauty of this “stacked fourths” method lies in its familiarity. Guitarists comfortable with standard tuning can readily adapt to the extended range without drastically altering their ingrained fretboard knowledge. The consistent intervals across the strings mean that scale patterns and chord shapes translate relatively easily from a 6-string or even a 7 or 8-string guitar. This makes the learning curve for a 9 string guitar less steep, especially for players who want to immediately apply their existing techniques in a lower register.
However, while extending standard tuning downwards is a practical starting point, some players explore alternate tuning approaches to unlock different sonic possibilities on a 9 string guitar. One interesting concept involves shifting the major third interval found in standard tuning. In standard tuning, the major third interval occurs between the G and B strings. By strategically moving this interval, you can create tunings that offer unique chord voicings and playability. For instance, on a 7 string guitar, tuning to BEADF#BE shifts the major third interval between the D and F# strings (4th and 3rd). Applied to an 8 string guitar, F#BEAC#F#BE tuning continues this concept. This kind of tuning can be thought of as creating a baritone-esque feel while retaining a high string, offering interesting chord possibilities.
When it comes to 9 string guitars, the lowest strings, particularly the lowest two, often become dedicated to bass frequencies. While chording across all nine strings is technically possible, achieving a clear and musically useful sound in the lowest registers can be challenging. The sheer depth of the lowest strings can sometimes muddy the overall sonic texture, especially in complex chords. Therefore, many 9 string guitarists focus on using the lowest strings for single-note riffs, bass lines, or power chords, reserving more complex chord voicings for the higher strings.
Ultimately, the best tuning for your 9 string guitar depends on your musical goals and playing style. While extending standard tuning downwards provides a familiar and accessible entry point, experimenting with alternate tunings can uncover unique sounds and inspire new musical ideas. Exploring different approaches to tuning and voicing is key to fully harnessing the expansive potential of the 9 string guitar.
