Chord Naming Conventions
From the name of a chord you can tell at a glance which tones belong to the chord. The Root, Major Third, and Perfect Fifth are implicit in chords which don't specify them. If any of these three basic tones are missing (or unsubstituted) then they appear at the end of the chord name in parentheses.
