The G Major scale is the most common second scale taught after C Major. Its notes — G, A, B, C, D, E, F♯, and G — use the same white-key pattern as C Major with one important change: the seventh note is F♯, not F natural. That single sharp makes G Major the first key signature most pianists learn to read on the staff, and the F♯ also gives the scale its bright, distinctive "leading tone" that pulls strongly back to G.
G Major sits one step clockwise from C on the circle of fifths, which is why it shares six notes with C and only changes one. Its relative minor is E Minor (same key signature, different home note), and its parallel minor is G Minor. The diatonic chords in G — G, Am, Bm, C, D, Em, F♯° — power some of the most-played songs in folk, country, classical, and rock. G Major is also a favorite key for guitar, which means a huge amount of the popular-music repertoire is written in it.
The right-hand fingering is the standard 1-2-3-1-2-3-4-5 pattern, identical to C Major. The thumb tucks under between B and C, and the F♯ falls naturally under finger 4. It feels almost the same as C — the only adjustment is keeping finger 4 ready for a black key on the way up.
