Exploring Scales and Key Signatures

Scales are the building blocks of music. A scale is a sequence of notes in ascending or descending order, forming the foundation for melodies and harmonies.

Major and Minor Scales

• Major scales sound happy and bright. The pattern of whole steps (W) and half steps (H) is: W-W-H-W-W-W-H (e.g., C major: C-D-E-F-G-A-B-C).
• Minor scales sound sadder or more serious. The natural minor pattern is: W-H-W-W-H-W-W (e.g., A minor: A-B-C-D-E-F-G-A).

Key Signatures

The key signature tells you which notes are consistently sharp or flat. It appears at the beginning of each staff line, right after the clef.

• Sharps or flats in the key signature help you instantly recognize the key of the piece and play the correct notes.

Circle of Fifths

The Circle of Fifths is a visual tool to understand key signatures and how closely related keys are.
