In one sentence: G major keeps the major formula and introduces F#, the only black key in the route.

The scale map

Formula: W-W-H-W-W-W-H · Degrees: 1-2-3-4-5-6-7

• Key signature: one sharp, F#
• Relative minor: E minor, using the same notes around a different center
• Chords: G, Am, Bm, C, D, Em, F#dim

How to play it

Right hand

• Up, 1 octave: 1-2-3-1-2-3-4-5
• Down, 1 octave: 5-4-3-2-1-3-2-1
• Up, 2 octaves: 1-2-3-1-2-3-4-1-2-3-1-2-3-4-5
• Down, 2 octaves: 5-4-3-2-1-3-2-1-4-3-2-1-3-2-1

Left hand

• Up, 1 octave: 5-4-3-2-1-3-2-1
• Down, 1 octave: 1-2-3-1-2-3-4-5
• Up, 2 octaves: 5-4-3-2-1-3-2-1-4-3-2-1-3-2-1
• Down, 2 octaves: 1-2-3-1-2-3-4-1-2-3-1-2-3-4-5

Practise E-F#-G as one link, without accenting F# or rushing the arrival.

Scale, chords, and direction

Then try G-D-Em-C. The scale supplies every note in these four chords, but each note still changes function over the current chord.

The circle of sharps continues in this order: F#-C#-G#-D#-A#-E#-B#. Today you only need to integrate F#.

Listening and context

Bach’s Cello Suite No. 1 and Mozart’s Eine kleine Nachtmusik are in G major. Do not use them as a recipe for mood: they let you hear how one scale changes with instrument, rhythm, and texture.

Common mistakes

• Playing F natural: locate F# before starting.
• Hitting F#: finger 4 should continue the same gesture, not add an accent.
• Rushing E-F#-G: practise those three notes with an even pulse.
• Confusing “relative” with “identical”: G major and E minor share notes but rest around different centers.
• Assigning one universal character: arrangement and performance matter more than the isolated key.

Quick check

• I can find G-A-B-C-D-E-F#
• I distinguish F# from F natural
• I can play one octave with each hand
• I can play I-IV-V-I: G-C-D-G
• I know E minor shares the same notes

Keep this: F# does not decorate G major; it completes the distance that leads back to G.
