The rise of seven strings

The seven-string guitar, once a niche instrument, is now a staple in modern metal. Its story begins not in the aggressive world of djent, but with jazz fusion pioneer Allan Holdsworth in the 1970s. He sought a wider tonal palette and extended range, modifying a Gibson ES-335 to accommodate the extra string. This wasn't about heavier riffs; it was about harmonic possibilities.

The real explosion came in the late 90s and early 2000s, driven by bands like Meshuggah and Dream Theater. These groups needed lower tunings without sacrificing clarity or playability. The 7-string solved this problem, allowing for crushing riffs and complex harmonies simultaneously. It wasn’t just about going lower; it was about expanding the sonic landscape.

Today, the 7-string market is robust, though perhaps not experiencing the explosive growth of the early 2000s. Brands like Ibanez, Schecter, ESP, and Jackson consistently offer popular 7-string models. You'll find options ranging from affordable instruments under $500 to high-end, custom-built guitars exceeding $3000. The 7-string is here to stay, offering a unique voice for metal guitarists.

Tuning and string gauge

Choosing the right tuning is the first step with a 7-string. Standard tuning is B E A D G B e, but many players opt for lower tunings. Drop A (A E A D G B e) is incredibly popular for its heavy sound, while others experiment with even lower options like Drop G or even lower. The tuning dictates the string gauge you’ll need.

Heavier strings are essential to maintain adequate tension at lower tunings. Using too light a gauge will result in flabby, indistinct notes. A common setup for Drop A is a .010-.056 gauge set, but this varies depending on scale length and personal preference. Nickel-wound strings offer a warmer, more traditional tone, while stainless steel strings provide increased brightness and longevity.

High tension can warp a neck or ruin intonation. Check the tension specs for your specific scale length before you buy a heavy set. If the neck starts bowing and the truss rod won't budge, take it to a tech. It is better to be cautious than to snap a nut or pull the bridge out of the wood.

  1. Standard: B E A D G B e
  2. Drop A: A E A D G B e
  3. Drop G (G E G D G B e) for extreme low-end
  4. Other: Experiment with lower tunings, but be mindful of string tension.

Rhythm beyond power chords

The 7-string opens up new rhythmic possibilities beyond standard power chords. Palm muting, a cornerstone of metal rhythm guitar, takes on a different dimension. The lower B string allows for deeper, more resonant palm-muted chugs. Experiment with varying the amount of palm muting to create dynamic textures.

Syncopation is crucial for creating interesting rhythmic patterns. Instead of just hitting chords on the beat, try emphasizing off-beats or using rests to create a sense of groove. Polyrhythms – playing two or more different rhythms simultaneously – are also effective, adding complexity and a sense of unease. Meshuggah are masters of this, layering intricate polyrhythms to create their signature sound.

The low B string itself is a percussive element. You can use it for muted strums, creating a driving, rhythmic foundation. Bands like Periphery frequently use this technique, blending percussive elements with complex chord voicings. This approach is central to the 'djent' sound – a heavily palm-muted, syncopated style characterized by a percussive attack.

Lead playing and the fretboard

The extra string dramatically expands the fretboard for lead playing. Scale shapes need to be re-imagined, incorporating the new low B string. This allows for wider intervals and more complex melodic ideas. Think beyond the standard pentatonic scales – the 7-string encourages exploration of more exotic scale choices.

Arpeggios benefit greatly from the extended range. You can create wider, more dramatic arpeggios that span multiple octaves. Tapping techniques also translate well to the 7-string, allowing for fast, fluid lines. The extra string provides more options for tapping patterns and harmonic variations.

Sweep picking and legato feel different on a wider neck. The spacing requires a larger arc with your picking hand, which can throw off your timing if you are used to a six-string. Alternate picking is just as necessary here, though the thicker low string has more resistance and requires a firmer grip on the plectrum to keep notes snappy.

  1. Incorporate the low B into your existing scale shapes to avoid getting stuck in 'six-string mode'.
  2. Arpeggios: Explore wider, more complex arpeggio patterns.
  3. Tapping: Utilize the extended range for creative tapping sequences.

Mastering the Common 7-String Arpeggio Shape

1
Understanding the Shape & Tuning

Before diving in, ensure your 7-string is tuned to standard B tuning (B E A D G B e). This arpeggio shape is based around a minor key, and will be presented using the A minor scale as an example. The root note will be on the 7th string. This shape is movable, meaning you can shift it up and down the neck to play different minor arpeggios. Familiarize yourself with the notes on the 7th string to quickly identify the root.

2
Finger Placement - Part 1

We'll start with a common voicing. Place your index finger on the 7th string, 5th fret (A). Your middle finger goes on the 6th string, 5th fret (E). Your ring finger goes on the 5th string, 6th fret (A). Finally, your pinky finger goes on the 4th string, 7th fret (D). This forms the core of the arpeggio.

3
Finger Placement - Part 2

Continue the shape. Place your index finger on the 3rd string, 5th fret (G). Your middle finger goes on the 2nd string, 5th fret (B). Your ring finger goes on the 1st string, 5th fret (E). Ensure each finger is arched and pressing down cleanly behind the fret for a clear sound. Avoid muting adjacent strings.

4
Picking Direction & Pattern

Use alternate picking for this arpeggio. Start with a downstroke on the 7th string. Then, upstroke on the 6th, downstroke on the 5th, upstroke on the 4th, downstroke on the 3rd, upstroke on the 2nd, and downstroke on the 1st. This creates a smooth, flowing sound. Focus on consistency and accuracy.

5
Practice Tempo & Rhythm

Begin practicing slowly, around 60-70 BPM (beats per minute). Use a metronome to ensure consistent timing. Focus on clean articulation and avoid rushing. Gradually increase the tempo as your accuracy improves. Aim for a fluid, even rhythm.

6
Movable Shape Application

Now, move the entire shape up and down the neck. For example, shifting the entire shape two frets higher will result in a B minor arpeggio (root on the 7th string, 7th fret). Experiment with different root notes to understand how the shape translates across the fretboard.

7
Adding String Skipping

Once comfortable, introduce string skipping. Instead of playing the arpeggio sequentially, try picking only the root notes on the 7th and 6th strings, then the 5th and 4th, and so on. This adds a wider, more modern metal sound. Maintain alternate picking throughout.

Chords and harmonic color

The 7-string unlocks a wealth of harmonic possibilities beyond standard chord progressions. Extended chords – 9ths, 11ths, and 13ths – become more accessible and sonically rich. The extra string allows for more complete voicings, adding depth and complexity to your chords.

Altered voicings – incorporating altered extensions like #9s and b13s – create dissonance and tension. These voicings are essential for creating a modern, progressive metal sound. The low B string is particularly useful for creating root-5 power chords, which offer a thick, powerful tone.

Moving beyond basic chord progressions is key. Experiment with inversions, slash chords, and unusual chord combinations. The 7-string encourages harmonic exploration, allowing you to create unique and captivating textures. Don't be afraid to venture outside of traditional harmonic frameworks.

Players to watch

Studying the work of influential 7-string players is a great way to improve your own playing. Tosin Abasi (Animals as Leaders) is a pioneer of the instrument, known for his incredibly technical playing and innovative use of tapping and sweeping. His music is a masterclass in harmonic complexity and rhythmic precision.

Plini is another modern master, celebrated for his melodic and atmospheric compositions. His playing is characterized by its fluidity, expressiveness, and unconventional chord voicings. Wes Hauch (Alluvial, Devin Townsend Project) is known for his aggressive riffs and blistering solos. He seamlessly blends technical proficiency with raw emotion.

These players represent the forefront of 7-string guitar playing. Analyzing their techniques, studying their transcriptions, and immersing yourself in their music will undoubtedly elevate your own skills. Resources like Songsterr and Ultimate Guitar offer tabs and lessons for many of their songs. Don’t just copy their licks; strive to understand the underlying principles that make their playing so unique.
