Key Signature

Determining the Key

The key signature is placed after the time signature indicating the key or pitch range of the scaling system for the appropriate instrument with a series of sharp or flat signs. Depending upon the key, the signature could contain one or several sharp or flat symbols. See also Keys and Chords and Chromatic Intervals for key breakdown, assignment, and reference.

Key Marks & Accidentals

Key Marks, also called Accidentals or Key Symbols are placed next to the note when changing its pitch during the composition. The natural key symbol is never used in the key signature. Illustrated below are the key marks.

Natural: used to remove a sharp or flat from a note
Sharp: used to raise the pitch of a note by one-half step
Double-sharp: used to raise the pitch of a note by one full step
Flat: used to lower the pitch of a note by one-half step
Double-flat: used to lower the pitch of a note by one full step
