How to Write Harmonies on the Guitar

Writing harmonies on the guitar can feel like a musical puzzle, but once you get the hang of it, the results can be truly rewarding. Whether you’re aiming to add depth to your metal riffs or enrich your acoustic ballads, understanding how to construct harmonies will open up a world of creative possibilities. We’ll break down the process and offer practical insights to help you craft harmonies that sing, soar, and slam right alongside your lead melodies.

Understanding Intervals: The Building Blocks of Harmony

When it comes to writing harmonies, the first thing you need to wrap your head around is intervals. Intervals are the distances between two notes, and they form the backbone of any harmony. The most common intervals used in guitar harmonies are thirds and fifths, but don’t let that limit you. Experimenting with different intervals can yield some unexpected and exciting results.

• Thirds: This interval is the bread and butter of harmony. It’s used extensively in both major and minor scales. When you harmonize a melody in thirds, you’re essentially playing a note that’s two steps above each note in your original melody.
• Fifths: The fifth is another powerful interval, often used to create power chords. It gives a strong and stable sound and is a staple in heavy metal harmony.
• Sixths and Sevenths: These can add a bit more tension and color to your harmonies. Sixth intervals are often used to create a more open, airy sound, while sevenths can add a touch of dissonance.

Interestingly enough, when you start to combine different intervals, you can create harmonies that evoke different emotions and vibes, from the uplifting to the downright eerie.

Choosing Your Scale: Major vs. Minor

The choice between major and minor scales will significantly affect the mood of your harmonies. Major scales tend to sound happy and bright, while minor scales offer a more somber or aggressive tone, which is why they’re often favored in metal genres.

Let’s say you’re working with a melody in the A minor scale. To harmonize it, you’ll want to stick with notes from the same scale. This ensures that your harmonies will sound cohesive and consonant.

• Experiment with Modes: If you’re feeling adventurous, delve into modal harmonies. Modes like Dorian or Phrygian can add a unique flavor to your harmonies, especially in progressive metal.
• Use the Pentatonic Scale: This is a great choice for those bluesy or rock-infused harmonies. The pentatonic scale, with its five notes, is simple yet incredibly versatile.

While it’s hard to say for sure which scale will work best for every situation, playing around with different options will help you find what resonates with your musical vision.

Parallel vs. Counterpoint Harmonies

Now that you’ve got an idea of the intervals and scales, it’s time to explore how to weave them together. There are two primary ways to approach harmonizing a melody: parallel harmonies and counterpoint.

• Parallel Harmonies: This is when the harmony follows the melody note-for-note but at a different pitch. Think of it as a shadow that mimics every move the melody makes. This approach is straightforward and effective, especially in metal riffs where precision and power are key.
• Counterpoint Harmonies: Here, the harmony moves independently, creating a more intricate interplay of notes. This can be more challenging to write but offers a richer and more dynamic sound.

When crafting counterpoint, keep in mind that the harmony should complement the melody, not compete with it. The aim is to enhance the overall sound, not overshadow it.

The Role of Rhythm in Harmonies

Harmonies aren’t just about which notes you play—how you play them rhythmically is just as important. In genres like djent or metalcore, rhythm plays a pivotal role in creating that punch and drive.

• Syncopation: This involves playing off the main beats, giving your harmonies a more complex and engaging feel. It’s often used in progressive metal to create a sense of movement and unpredictability.
• Rhythmic Variations: While the melody might follow a straightforward 4/4 rhythm, experimenting with triplets or odd time signatures in your harmony can add an unexpected twist.

Consider how rhythm can add another layer of interest to your harmonies. It’s not just what you play, but when you play it that can make all the difference.

Employing Dynamics for Emotional Impact

Dynamics refer to the volume and intensity with which you play your harmonies. This can have a huge impact on the emotional tone of your music. In the world of metal, dynamics are often used to build tension and release.

• Crescendo: Gradually increase the volume of your harmonies to build excitement.
• Diminuendo: Conversely, you can decrease the volume to create a more introspective or haunting vibe.

Think about how the dynamics of your harmonies can contribute to the overall narrative of your piece. They’re a powerful tool for conveying emotion and intensity.

Using Technology to Perfect Your Harmonies

Technology can be a great ally in crafting harmonies, especially when you’re working with complex arrangements or need a little help with precision. Tools like digital audio workstations (DAWs) and guitar effects pedals can offer a wealth of options.

• DAWs: Use software like Logic Pro or Ableton Live to experiment with different harmonies without having to play them live. These programs offer features like MIDI programming and pitch shifting, which can be invaluable for testing out ideas.
• Effects Pedals: Harmonizer pedals can help you create live harmonies on the fly. They track your playing and add harmonized notes in real time, which is especially useful in live settings.

While technology can offer amazing possibilities, remember that it’s just a tool. The real magic comes from your creativity and musical intuition.

Learning from the Best: Analyze and Adapt

One of the best ways to improve your harmony writing is to study and learn from those who have mastered it. Look to your favorite bands and artists for inspiration. How do they use harmonies to enhance their music?

• Transcribe Songs: Break down the harmonies in your favorite tracks. Try to understand why they work and how they fit into the overall arrangement.
• Attend Lessons: Platforms like Riffhard offer lessons from world-class metal guitarists. Learning from the pros can provide insights and techniques you might not discover on your own.

Analyzing and adapting what you learn from others can be a great way to refine your own style and expand your harmonic vocabulary.

Practice, Patience, and Persistence

Like any musical skill, writing harmonies on the guitar takes practice. Don’t get discouraged if your first attempts don’t sound exactly as you envisioned. Keep experimenting, and over time, you’ll develop a knack for creating harmonies that resonate.

• Set Aside Regular Practice Time: Consistency is key. Even short, daily practice sessions can lead to significant improvements over time.
• Record and Review: Recording your harmonies can give you a fresh perspective and help you identify areas for improvement.

Remember, every small step forward is progress. With patience and practice, you’ll find your voice and style in the world of guitar harmony.
