What Gmaj9 is made of
Gmaj9 (G major ninth) is built from the notes G, B, D, F#, A, with the interval pattern 1, 3, 5, 7, 9.
Stack 1, 3, 5, 7 and 9 on a root of G and you get G, B, D, F# and A. That interval recipe is what makes the chord a major ninth chord — move the same shape to another root and the character travels with it, which is why Cmaj9 sounds like a transposed Gmaj9.
Major 9th: Lush, gentle; jazz ballads and neo-soul.
Spelling: the notes above are written the way a score would write them, not simplified to the nearest piano key. That is why this chord is spelled with F♯ rather than its enharmonic equivalent.
