![]() ![]() So if you want that kind of differentiation, turn your distortion down until power chords sound boring and use full chords instead. That means that a seventh is sort of redundant (and the distortion seventh you hear is a bit lower than a proper seventh anyway so they'd clash), and a minor chord is really going to mess and muddy up what you already have there sound-wise. So assuming strong distortion, the main motivation for power chords, you already have the character of a major chord, and the character of a seventh chord wrapped into your sound. The first two overtones are the fundamentals you started with, then an octave above your lower fundamental, then a pure major third above that, another fifth, and then a seventh. So the fundamental frequency of the resulting signal is an octave below what you play, but due to the distortion, it has a number of overtones. Now if we are talking about a pure fifth, the frequency of the fifth is 3/2 that of the base frequency, and the frequency difference then is 1/2 of the base frequency, an octave below. That's why a power chord does not sound all that impressive when played through a clean amp. Power chords are used in connection with distortion, and distortion produces frequencies that are not there to start with. You'll maybe wonder why you thought power chords could be the answer to everything, as by then, you'll hear some great harmony, and sound like a muso! with majors and minors, move on to 7ths - there are 3 main 7ths to play, dominant, with a major 3 and b7 minor, with a minor 3 and b7 and major, with a major 3 and major 7. It's time to play 'proper' chords, by the sound of it, using at least three different note names, spread out over the frets, sometimes doubled. Power chords - 5ths - just don't do that.In E-shaped barre chords, the 3rd string usually provides the 3rd of the chord, so no longer are you playing a 'power chord'. I say defining because 3 tells if a chord is major or minor. Trouble is on guitar, there's no space to put the defining 3 or 7 in between - you've used up the bottom 2, sometimes 3 strings. It doesn't matter which, because the two notes will be the same for each key. ![]() Power chords are made up from 1 and 5 of any major or minor scale. ![]()
