What Gm9 is made of
Gm9 (G minor ninth) is built from the notes G, Bb, D, F, A, with the interval pattern 1, b3, 5, b7, 9.
Stack 1, b3, 5, b7 and 9 on a root of G and you get G, Bb, D, F and A. That interval recipe is what makes the chord a minor ninth chord — move the same shape to another root and the character travels with it, which is why Cm9 sounds like a transposed Gm9.

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 B♭ rather than its enharmonic equivalent.
