Master Key Signatures & The Circle of Fifths for Beginners

Accidentals are note alterations like sharps, flats, and naturals.
Sharps raise a note by a half step, flats lower it by a half step, and naturals return the note to its original state.
Key signatures indicate consistent alteration of note pitches throughout a piece.
The circle of fifths is a tool to understand the relations between different keys.
Moving clockwise on the circle of fifths adds a sharp with each step.
Moving counterclockwise on the circle of fifths adds a flat with each step.
Every major key has a relative minor key.
The circle of fifths helps in defining key signatures, modulating songs, and composing and improvising music.
