The Basic Riff and Tuning

"Kryptonite" by Three Days Grace uses standard tuning (E-A-D-G-B-E from lowest to highest string), so you do not need to retune your guitar. The song is built around a single, repeating riff that sits mostly on the low E and A strings. This riff is the backbone of the entire song—once you lock it in, you have the foundation for playing along with the recording.

The main riff uses power chords and single notes played in a steady, driving rhythm. The tempo sits around 100 beats per minute, which is moderate enough to learn at a slower speed first. Start by playing the riff without worrying about speed; focus on hitting the right frets and keeping your rhythm clean. You can always speed up once your fingers know where to go.

Key Takeaways

  • The song uses standard tuning and centers on a repeating riff played mostly on the low E and A strings.
  • The main riff combines power chords and single notes in a steady rhythm at roughly 100 beats per minute.
  • Practice the riff slowly first, then gradually increase speed once your finger placement becomes automatic.
  • The verse and chorus use the same riff with slight variations in how you mute and accent the notes.
  • A capo is not needed, and the song works well for intermediate players who understand power chords.

Playing the Main Verse Riff

The verse riff starts on the low E string (the thickest string). Place your index finger on the 3rd fret of the E string and play that note. Then move to the A string (the second-thickest string) and play the 5th fret with your middle finger. This two-note pattern repeats as the foundation of the riff. The rhythm is steady eighth notes, meaning you pick down-up-down-up in a consistent pattern without stopping.

After playing those two notes a few times, the riff adds a note on the D string (3rd fret). This creates a three-note pattern that cycles through the verse. Keep your picking hand moving at a steady pace even when you are not playing a note—this keeps your rhythm locked in. Mute the strings between notes by lightly touching them with your fretting hand so you hear the rhythm but not unwanted string noise.

Practice this section for 5 to 10 minutes at a time, starting at half speed. Use a metronome set to 50 beats per minute, then gradually move up to 75, then 100. Your goal is to play the riff without thinking about where your fingers go. Once it feels automatic, the rest of the song becomes much easier.

The Chorus and Power Chord Section

The chorus shifts to a heavier sound using power chords. A power chord uses only two notes—the root note and the fifth—played together. For this song, you will play power chords on the low E and A strings. The most common chord in the chorus is an E5 power chord: index finger on the 2nd fret of the A string, middle finger on the 2nd fret of the D string. Strum both strings together in a downward motion.

The chorus also uses an A5 power chord (index on the 0th fret of the A string, middle on the 2nd fret of the D string) and a B5 power chord (index on the 2nd fret of the A string, middle on the 4th fret of the D string). These three chords cycle through the chorus in a repeating pattern. The rhythm is quarter notes—one pick stroke per beat—which is slower and heavier than the verse riff. This contrast between the fast verse and the heavy chorus is what makes the song memorable.

Muting and Dynamics

Three Days Grace uses heavy string muting to create a tight, controlled sound. Muting means touching the strings lightly with your fretting hand so they do not ring out fully. In the verse, after you play a note, rest your finger on the string without pressing down hard. This kills the note's sustain and creates the percussive, punchy sound you hear on the recording.

In the chorus, mute between power chords by briefly touching all the strings with your fretting hand. This stops the previous chord from ringing into the next one. The effect is a series of distinct hits rather than a flowing chord progression. Practice muting by playing a note, then when ready touching the string to stop it. You should hear a clear difference between a ringing note and a muted one. Once you can control this, your playing will sound much closer to the original recording.

Building Speed and Accuracy

Start by playing the entire song at 60 beats per minute using a metronome. Play through the verse riff, then the chorus, then back to the verse. Do not worry about hitting every note perfectly—focus on keeping time with the metronome and maintaining consistent muting. Repeat this cycle 3 to 5 times, then take a break. Your hands need time to build muscle memory.

After a few practice sessions, increase the metronome to 75 beats per minute and repeat. Then move to 90, then 100. This gradual approach prevents bad habits from forming. If you jump straight to full speed, you will likely develop sloppy timing or inconsistent muting that becomes hard to fix later. Spend at least one week at each speed level before moving up. Once you can play the entire song cleanly at 100 beats per minute, you are ready to play along with the recording.

Common Mistakes and How to Avoid Them

The most common mistake is playing the verse riff too fast too soon. Many players rush because the riff sounds straightforward, but the muting and rhythm require precision. Slow down and nail the technique first. Another mistake is not muting between notes, which makes the verse sound muddy and unclear. Your fingers should be constantly touching strings to control the sound.

A third mistake is using too much pressure when fretting. You only need enough pressure to make the note ring clearly—pressing harder tires your hand and slows you down. Use light pressure and let your fingers rest on the strings for muting. Finally, do not skip the chorus. Many players focus only on the verse riff and then struggle when the chorus arrives. Practice the full song structure from the beginning so both sections feel natural.

Playing Along with the Recording

Once you can play the song cleanly at full speed, play along with the original recording. Start by playing just the verse riff while the song plays. Listen to how your timing lines up with the drums and bass. If you are rushing or dragging, adjust your tempo. After a few run-throughs, add the chorus. Then play the entire song from start to finish.

Playing along with the recording teaches you how the guitar part fits into the full band sound. You will hear how the drums drive the tempo and how the bass complements your riff. This is where the song comes alive. Record yourself playing along and listen back—you will hear timing issues and muting problems that you might miss while playing. Use these recordings to identify what needs work in your next practice session.

Frequently Asked Questions

Do I need a capo to play this song?

No. The song is played in standard tuning with no capo. All the notes come from fretting the strings at specific frets on an unmodified neck.

What if I cannot play the riff at full speed yet?

Play it slower. Use a metronome at 50 or 60 beats per minute and focus on accuracy over speed. Speed comes naturally once your fingers know the pattern. Most players need two to four weeks of regular practice before they can play the full song at tempo.

Is this song good for intermediate players?

Yes. You need to understand power chords and be comfortable with basic muting techniques, but the riff itself is not technically difficult. It is a great song to build rhythm control and timing.

How long should each practice session be?

Fifteen to thirty minutes is ideal. Practice the verse riff for 10 minutes, the chorus for 5 minutes, then play through the whole song once. Short, focused sessions build skill faster than long, unfocused ones.

Can I use a pick or should I use my fingers?

Use a pick. The song requires steady, controlled picking strokes, and a pick gives you the precision and speed you need. A medium-gauge pick (0.73 mm to 0.96 mm) works well for this style.
