In sheet music notation, there is a lack of uniformity in writing chord symbols. For example the C major seven chord can be written as "Cmaj7" (used in this book), "CM7" or "CM7". The following table outlines the symbols used in this book, together with correct pronunciation and alternative symbols used for each chord type.
In sheet music, chord symbols that indicate a specific bass note to play are sometimes used. For example, C/G indicates a C chord with a G bass note (it may also be written C/G bass). The bass note will not always be a note of the chord; for example, Am/G is an A minor chord with a G bass note, which could also be called Am7.
