Beyond Chords: A Creative Approach to Guitar Arranging
Many guitarists begin arranging by asking a simple question:
"What chord fits under this melody?"
While harmony is certainly important, great arrangements often go far beyond simply adding chords. They create interest through imitation, texture, effects, variation, and careful use of the instrument's unique capabilities.
In a recent arranging lesson, we explored how a simple melody from How to Train Your Dragon could be transformed into a rich and expressive guitar arrangement. Along the way, several powerful arranging techniques emerged.
Start with the Fundamentals
Before adding complexity, it is important to establish a solid harmonic foundation.
A useful starting point is the primary chords:
I (Tonic)
IV (Subdominant)
V (Dominant)
From there, an arranger can create variety by:
Using seventh chords
Adding non-chord tones
Employing thirds, sixths, and octaves
Exploring different bass notes and inversions
These techniques provide a strong harmonic framework, but harmony is only one dimension of arranging.
Effects Are Part of the Arrangement
The guitar offers many colours that can become part of the musical story.
Natural harmonics, slides, percussion effects, rasgueados, tremolo, and rolled chords all provide opportunities to create contrast and atmosphere.
In this arrangement, harmonics became a particularly effective way of highlighting important moments and adding a sense of wonder to the music.
Rather than thinking of effects as decorations, think of them as compositional tools.
Think Horizontally, Not Just Vertically
Many arrangers focus exclusively on vertical thinking: stacking notes into chords.
An equally powerful approach is horizontal thinking—creating additional melodies.
One of the simplest ways to do this is through imitation.
Imitation occurs when a melodic idea is echoed by another voice shortly afterwards. A familiar example is the children's round:
"Row, Row, Row Your Boat."
Because each singer enters at a different time, the melody interacts with itself, creating a form of counterpoint.
In arranging, imitation can:
Fill empty space
Add movement
Create the illusion of multiple performers
Increase musical sophistication
Even a short melodic fragment can become dramatically more interesting when answered by another voice.
Strict and Loose Imitation
Not all imitation is identical.
Strict Imitation
The melody is repeated exactly, preserving both rhythm and pitches.
Loose Imitation
The melodic shape remains recognizable, but the rhythm, intervals, or contour may be adjusted.
Loose imitation is often easier to use in practical arrangements because it allows the arranger to maintain pleasant intervals and avoid awkward clashes.
When experimenting with imitation, pay special attention to intervals such as:
Octaves
Thirds
Sixths
These intervals often produce smooth, natural-sounding results.
Arranging Is Often Controlled Composition
At some point, arranging begins to resemble composing.
Rather than merely adding harmony, the arranger starts generating new material according to specific rules and patterns.
This is similar to how strong chess players think. They are not making random moves; they are working within systems, patterns, and possibilities.
Likewise, arrangers often use structured techniques such as imitation, sequences, variation, and counterpoint to generate musical ideas.
Explore Different Textures
Texture refers to how the musical material is presented.
The same melody and harmony can feel completely different depending on the texture used.
Some common guitar textures include:
Chordal Texture
All notes sound together.
This can be:
Thick (many notes)
Thin (fewer notes)
Arpeggiated Texture
The notes of a chord are spread out rather than played simultaneously.
Arpeggios create motion and can dramatically increase the sense of flow.
Tremolo Texture
A repeated note creates the illusion of sustained melody.
Pedal Texture
A single repeated or sustained note remains constant while other notes move around it.
The guitar is especially effective at pedal textures because open strings can continue ringing while the melody develops.
The Power of the Pedal Note
One of the most effective arranging techniques explored in the lesson was the use of a pedal note.
An open string—particularly the low E or high E—can be repeated against changing melodic material.
This creates:
Harmonic stability
Resonance
Momentum
A distinctly guitaristic sound
Pedal notes are often simple to execute but remarkably effective.
Creating Hidden Melodies
One fascinating aspect of arpeggiated textures is that they can contain more than one melody.
There may be:
The main melody
A bass line
An implied inner melody
Sometimes a single note change can create a beautiful inner voice that listeners perceive subconsciously.
Great arrangers pay attention not only to the top voice, but also to what is happening in the middle of the texture.
Use Chromatically Altered Chords
Once the basic harmony is established, surprising colours can be introduced through chromatically altered chords.
One useful question is:
"What chord contains my melody note but doesn't belong to the key?"
This often leads to unexpected yet expressive harmonic choices.
A single altered note can transform an otherwise predictable progression and add emotional depth.
Variation Through Augmentation
Another powerful technique is augmentation.
Augmentation occurs when a melody is slowed down by lengthening its note values.
The pitches remain the same, but the rhythm expands.
This can:
Create a sense of arrival
Build anticipation
Prepare a climax
Increase emotional weight
In the lesson, slowing a melodic fragment created a more natural transition toward the climactic harmonics.
Exploit the Guitar's Unique Strengths
Perhaps the most important lesson is that great guitar arrangements embrace what the instrument does best.
The guitar offers:
Open-string pedals
Natural harmonics
Arpeggios
Tremolo
Rolled chords
Multiple voices
Resonant sustain
Rather than forcing a piano score onto the guitar, successful arrangers allow the instrument itself to shape the music.
A Simple Arranging Checklist
When a melody feels too plain, consider:
Add harmonic support using I, IV, and V chords.
Introduce thirds, sixths, or octaves.
Use imitation or counterpoint.
Experiment with pedal notes.
Change the texture through arpeggiation.
Create inner melodies.
Add harmonics or guitar effects.
Try chromatically altered chords.
Use augmentation or rhythmic variation.
Finish with a distinctive guitaristic gesture such as rolled chords or harmonics.
Arranging is not merely about adding notes. It is about transforming a melody into something that feels complete, expressive, and uniquely suited to the instrument.
The more arranging techniques you learn, the more possibilities every melody contains.
