## Section6.2Lead–Sheet Symbols

Lead–sheet symbols (also known as “lead–sheet notation” and “lead–sheet chord symbols”) are often used as shorthand for chords in popular music and jazz. These symbols allow a guitarist or pianist to choose how to “voice” the chords, i.e., how they want to arrange the notes.

Lead–sheet symbols for triads communicate the root and quality of a chord.

 Lead–Sheet Symbol Chord Quality Notes in the Chord $\left.\text{F}\right.$ major $\text{F}$–$\text{A}$–$\text{C}$ $\left.\text{G}\text{m}\right.$ minor $\text{G}$–$\text{B}^♭$–$\text{D}$ $\left.\text{D}^{\circ}{}\right.$ diminished $\text{D}$–$\text{F}$–$\text{A}^♭$ $\left.\text{C}{+}\right.$ augmented $\text{C}$–$\text{E}$–$\text{G}^♯$

Here is a musical example with lead–sheet symbols and guitar tablature.

As you can see in the example above, major triads are represented by an uppercase letter ($\left.\text{A}\right.$, $\left.\text{E}\right.$, and $\left.\text{D}\right.$) while minor triads are represented with the root in uppercase followed by a lowercase “m” (e.g., $\left.\text{F}^♯{}\text{m}\right.$). Diminished triads are represented by including the diminished symbol ($\left.\text{}^{\circ}{}\right.$) after the chord root (e.g., $\left.\text{C}^{\circ}{}\right.$) while augmented triads are represented by including the augmented symbol after the root ($\left.\text{C}{+}\right.$).
