What Fmaj9 is made of
Fmaj9 (F major ninth) is built from the notes F, A, C, E, G, with the interval pattern 1, 3, 5, 7, 9.
Stack 1, 3, 5, 7 and 9 on a root of F and you get F, A, C, E and G. 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 Fmaj9.
Major 9th: Lush, gentle; jazz ballads and neo-soul.
