The symbols in Examples 2 and 3 are not comprehensive, but you can likely decode other variations based on the ones here. This is because chord symbols were created along the way as jazz developed and were never completely standardized. Notice that there are several ways to represent each non-major triad quality. Other symbols are added to indicate other triad qualities, as summarized in Example 2.Ĭhord symbol (for a chord with a root of C) If you see nothing but a note name as a chord symbol, this means to play a major triad. Basics of Chord Symbols TriadsĬhord symbols are based on the major triad as the norm. A complex symbol is given in Example 1, with annotations to show the various possible components of a chord symbol.
Chord symbols are also sometimes called “lead sheet symbols” because you will find them on lead sheets, which are jazz scores that typically notate only a melody and these chord symbols.Ĭhord symbols can pack a lot of information into a few letters. There are two systems of shorthand for discussing harmony used in this textbook: chord symbols and Roman numerals. There are four components to a chord symbol: 1) the root of the triad, 2) the quality of the triad, 3) the presence of extensions beyond the triad, and 4) the bass note. This textbook will use the sharp/flat system of showing alterations.Įxample 1. Both systems are prevalent in the real world when writing your own charts, pick one system and stick with it consistently. Alterations are shown through sharp and flat symbols, or through plus and minus symbols.
