How long does it take to get good at metal guitar?

Short answer

With focused practice most days, many players can play simple palm-muted riffs cleanly with a click within 3–6 months. Clean 16th-note picking at moderate tempos usually takes 1–2 years. Controlled speed and solos that hold up on a recording take several years. How you practice matters more than how long.

What "good" means to you

"Good" is really three different goals, and they take very different amounts of time:

  1. Play a simple song section cleanly with a click. Weeks to months if you follow a clear order like the beginner path.
  2. Get through intermediate riffs at the original tempo. Usually one to two years of steady work on picking and muting.
  3. Improvise or write leads that hold up on a recording. Years of deliberate work, and it keeps improving for as long as you play.

A rough timeline

These are typical ranges for someone practicing 20–45 focused minutes most days. Your mileage will vary, and that's fine.

AroundWhat's realistic
1–3 monthsPower chords with quiet unused strings, muted 8ths in time, your first simple riffs slower than the record.
3–6 monthsPalm-muted riffs cleanly with a click, open accents, basic alternate picking on one string, a minor pentatonic box.
6–12 monthsClean string changes, downpicking for a full verse, simple syncopated riffs, short solos that land on the root.
1–2 years16th-note riffs at moderate tempos, natural and harmonic minor, pinch harmonics on demand, full songs at or near tempo.
2–5 yearsFast, controlled picking, sweeps and tapping inside real solos, writing your own riffs and leads.
