What D6/9 is made of
D6/9 (D six nine) is built from the notes D, F#, A, B, E, with the interval pattern 1, 3, 5, 6, 9.
Stack 1, 3, 5, 6 and 9 on a root of D and you get D, F#, A, B and E. That interval recipe is what makes the chord a six nine chord — move the same shape to another root and the character travels with it, which is why C6/9 sounds like a transposed D6/9.

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.
