What a power chord is
A power chord is a two-note chord made of a root note and its fifth. Often a higher octave of the root is added, so you play three notes but only two different pitches. There is no third in a power chord, and the third is the note that makes a chord major or minor. That is why a power chord sounds strong and open, and why it fits over both major and minor music.
Power chords are the backbone of rock, punk and metal rhythm guitar. They are loud, simple and forgiving. A whole song can run on three power chords, and many famous songs do exactly that. If you want to play along with rock music quickly, power chords are the fastest route.
How this tool works
Pick a root note and the tool shows two fingerings: one with the root on the sixth string and one with the root on the fifth string. Each fingering lists the string and fret for the root, the fifth and the octave. It also names the notes, so you learn the music while you learn the shape.
The sixth-string shape is the one most players learn first. Put your index finger on the root note, your ring finger two frets higher on the next string, and your little finger two frets higher on the string after that. That gives root, fifth, octave. The fifth-string shape is the same idea one string lower.
How to play them cleanly
Mute the strings you are not playing. Lay your index finger lightly across the higher strings so they do not ring. Use the edge of your picking hand to mute the lower strings. A power chord with ringing open strings sounds messy, and muting is half the technique.
Pick with short, firm downstrokes for a punchy rhythm. For faster songs, alternate down and up strokes but keep the motion small. Let the amp do the loud work. On an acoustic guitar, power chords sound thinner, but they still work for practice and for quieter styles.
Moving around the neck
Because the shape never changes, you can move it anywhere. Slide the same shape from G to A to B and you have a chord progression. This is the real power of power chords: learn one shape, play in every key. Use the tool to find the frets for the roots in your song, then practise the slides slowly.
Watch the root note, not the whole shape. If you know where the roots are on the sixth and fifth strings, you can find any power chord in a second. The note names on those two strings are worth memorising, and this tool helps because it shows the root each time.
Common mistakes
The most common mistake is letting all six strings ring. Another is pressing so hard that the notes go sharp. A third is playing every power chord with the full three-note shape when two notes would sound tighter, especially with heavy distortion. Try the two-note version, root and fifth only, and hear the difference.
Do not rush. Play the progression slowly with a metronome, then speed up a little each day. Speed built on clean playing lasts. Speed built on sloppy playing falls apart on stage.
Going further
Once the two shapes feel easy, try adding a fourth note, or try palm muting: rest the side of your picking hand lightly on the strings near the bridge while you pick. Palm muting turns a ringing chord into a tight, percussive chunk, and it is the sound of most rock rhythm playing.
