Lesson 21: Key of G Major
  • Master the G major scale (one sharp: F#)
  • Understand key signature reading
  • Play melodies in G major
  • Learn about the circle of fifths

Introduction

Welcome to lower intermediate level! You now have solid command of basic notes and rhythms. Time to explore different keys systematically.

G Major Scale

G major has one sharp: F#. When you see the sharp symbol at the beginning of the staff (the key signature), play every F as F# unless told otherwise.

The Circle of Fifths

Keys are organized in the circle of fifths. Each step adds one sharp (going clockwise) or one flat (going counter-clockwise):

  • C major: no sharps or flats
  • G major: one sharp (F#)
  • D major: two sharps (F#, C#)
  • A major: three sharps (F#, C#, G#)

Understanding this pattern helps you learn all keys systematically.
