Chord chemistry is the study of how chords are constructed and how they interact with each other. By understanding chord theory, guitarists can better understand the fretboard and create interesting sounding chord progressions.
Chords are made up of notes that are played together. The root note is the starting point for the chord, and the other notes in the chord are based off of that root note. For example, a C major chord would have a root note of C, and the other notes in the chord would be E and G. Chords can be played in different positions on the fretboard, and they can be moved up or down in pitch to create different sounds.
Guitarists can use chord theory to create interesting sounding progressions by understanding how chords work together. Chords that have similar harmonic properties will sound good together, while chords that have conflicting harmonic properties will sound dissonant when played together. By understanding which chords sound good together, guitarists can create progressions that are pleasing to the ear.
