What C♯m7 is made of
C#m7 (C# minor seventh) is built from the notes C#, E, G#, B, with the interval pattern 1, b3, 5, b7.
Stack 1, b3, 5 and b7 on a root of C♯ and you get C#, E, G# and B. That interval recipe is what makes the chord a minor seventh chord — move the same shape to another root and the character travels with it, which is why Cm7 sounds like a transposed C♯m7.
