Guitar and keyboard chord notations are not the same. While both instruments use chord symbols to represent the combination of notes to be played together, the actual notation and positioning of the chords can differ.

Additionally, the voicing and arrangement of the notes within the chord may vary between guitar and keyboard. **

The chord that sounds similar to Bm on the guitar is D major. This is because Bm and D major share two of the same notes - D and F#. When playing a Bm chord, the D note is the root note, and when playing a D major chord, the D note is also the root note. This similarity in notes gives both chords a similar sound and feel. **
