How do some of our favorite groups get those distinctive sounds on seemingly familiar chords? One little trick involves creating pedal tones within a chord. A pedal tone is a sustained note that carries through changes in harmonies or chords. We usually think of a pedal tone as being in the lower or bass part of a chord or harmony, but there is nothing to prevent us from creating pedal notes in the higher notes of a chord.
Here are examples of pedal notes transforming otherwise familiar chords:
Chords like these are used quite a bit in rock music to change the sound and make it a bit more memorable.
Here are links to a few songs that make good use of these "pedal-type" chords.
Every Rose Has it's Thorn- Poison
Wonderwall- Oasis
You and Me- Lifehouse
