Lesson 3 – Introduction to Metal Guitar Riffs with the Palm-Mute Technique

Palm muting is a technique widely used in heavy metal to change the sound of single notes as well as power chords, giving them a thicker, shorter-ringing, and overall different tonal quality.

Compare the power chords I played with palm muting to how they sound when played regularly:

(With palm muting)
(Without palm muting)
 

To switch to palm muting, rest the edge of your picking hand on the strings near the bridge to slightly muffle them there.

While keeping your hand in this position, pick the strings with a plectrum as usual, and that's all there is to it! ;)

Experiment with varying amounts of pressure the heel of your picking hand applies to the strings, and with how close the hand is to the bridge, and find what sounds best for you.

In guitar tabs, palm mutes are indicated by the P.M. abbreviation.

If there's a series of palm mutes, the P.M. and a dotted line that follows designate the area where the palm muting technique should be applied.

When the dotted line ends, you lift the palm mute and play in a regular position.

Now let's play some riffs!

Riff 1

Slow Version
First riff in a sequence demonstrating palm muting technique

Pay attention that in the second half of the riff, the first chord in each bar is played without palm muting; the interplay between muted and non-muted power chords makes the riffs sound more interesting than if they were played entirely with a muffled tone.

Riff 2

Second riff in a sequence demonstrating palm muting technique with three-note power chords

Notice that the power chords in this phrase consist of three notes, where the highest note is simply a copy of the root note, but located an octave higher. This approach allows you to get a fatter distorted sound from the guitar.

This riff and the following riff, #4, connect perfectly into a theme. Practice each riff separately until you can play them accurately. After that, play them one after the other as a whole piece:

Fourth riff in a sequence demonstrating palm muting technique

Note that I play the riff slightly differently at the second time, by playing the 3rd bar twice, (the 4th bar is replaced with the 3rd one) and finishing up the phrase with the A power chord:
