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.All other extensions and added tones are assumed to be major/perfect.Sevenths added to the triad are assumed to be minor.Instead, symbols are always assumed to be a certain quality unless otherwise indicated: Chord symbols don’t reference a specific key.

Chord symbols tell you the root of the triad, the quality of the triad, any extensions to the triad, and any non- root bass note.
