What B♭m is made of
Bb Minor (Bb minor) is built from the notes Bb, Db, F, with the interval pattern 1, b3, 5. A common minor chord across many styles.
Stack 1, b3 and 5 on a root of B♭ and you get Bb, Db and F. That interval recipe is what makes the chord a minor chord — move the same shape to another root and the character travels with it, which is why Cm sounds like a transposed B♭m.
Minor: Dark, melancholic.
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.
