Metal music is known for its powerful and aggressive guitar tones, and one of the key techniques that contribute to this sonic assault is the pinch harmonic. Pinch harmonics, also known as artificial harmonics or squealies, are a guitar technique used extensively in metal to add a unique and piercing sound to riffs and solos. In this article, we’ll explore the pinch harmonic technique, how it works, and how you can incorporate it into your metal guitar playing.
What Are Pinch Harmonics?
Pinch harmonics are high-pitched, squealing overtones produced by the guitar strings when they are struck with a combination of pick attack and thumb or finger contact on the string. This technique allows guitarists to create harmonics at specific intervals along the string, producing a distinct and aggressive sound.
How to Perform Pinch Harmonics
Here’s a step-by-step guide to performing pinch harmonics:
- Hold Your Pick Correctly: To execute pinch harmonics effectively, you need to hold the guitar pick firmly between your thumb and index finger. The thumb’s side should be exposed, as this is what you’ll use to “pinch” the string.
- Select the Right Location: Pinch harmonics work best when you pick the string at specific nodal points, usually found 24 frets (two octaves) above the note you’re playing. These points can be calculated mathematically, but many guitarists develop a feel for where to pick through practice.
- Angle of Attack: When picking the string, use the edge of your thumb to lightly touch the string immediately after the pick strike. The angle and timing of this touch are crucial in producing the harmonic.
- Practice Control: Achieving consistent pinch harmonics requires precise control of your picking hand. Experiment with different pick angles, pick attack strength, and thumb placements to find the sweet spot for producing harmonics.
- Use Distortion and Gain: Pinch harmonics are most prominent when played through a distorted or high-gain amplifier. The added saturation enhances the harmonic content and gives it that signature metal edge.
- Experiment with String Bending: You can also create pinch harmonics while bending strings. This technique adds a dynamic, vocal-like quality to your solos.
Incorporating Pinch Harmonics into Your Playing
Now that you understand how to perform pinch harmonics, here are some tips for incorporating them into your metal guitar playing:
- Add Emphasis: Use pinch harmonics to emphasize specific notes in your riffs and solos. They are especially effective during fast and aggressive passages.
- Create Sonic Textures: Experiment with pinch harmonics to add texture and depth to your guitar solos. You can create eerie and otherworldly sounds by sliding your pinch harmonics along the fretboard.
- Rhythmic Patterns: Integrate pinch harmonics into your rhythm guitar playing by using them to accentuate downbeats or syncopated rhythms.
- Combine with Other Techniques: Combine pinch harmonics with techniques like palm muting, tremolo picking, and dive bombs to create a wide range of metal guitar effects.
- Practice and Experiment: Pinch harmonics require practice to master. Spend time experimenting with different strings, positions, and dynamics to find what works best for your style.
Conclusion
The pinch harmonic technique is a hallmark of metal guitar playing, contributing to the genre’s distinct and aggressive sound. While it may take time and practice to master, the results are well worth the effort. By incorporating pinch harmonics into your playing, you can add a new dimension to your metal guitar sound, making your riffs and solos stand out with their piercing and intense sonic character. So, grab your guitar, dial in some distortion, and start exploring the world of pinch harmonics to take your metal playing to the next level.
