Hitting the strings harder creates a better tone for metal because it produces a more aggressive, punchy, and defined sound—which suits the intensity of the genre. When you strike the strings with more force, especially through a distorted amp or pedal, it drives the signal harder and emphasizes the attack of each note. This gives your playing more clarity, tightness, and presence, helping riffs and palm-muted chugs cut through the mix.

In metal, tone isn't just about gear—how you play affects the sound just as much. A heavier picking hand adds weight and power to your tone, making everything sound more controlled and intentional. It also helps lock in tighter with the drums, especially for rhythm-focused metal styles. Just be sure to balance force with technique to avoid sounding sloppy or tense.
