It's difficult to determine without more specific information about the chord in question.

The guitar chord for B minor is played by placing your index finger on the second fret of the A string, your middle finger on the third fret of the B string, and your ring finger on the fourth fret of the D string.

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. Guitar chord notations typically show the frets and strings to be played, while keyboard chord notations show the specific keys to be pressed. 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#.

FM and FM chord guitar are two different things. FM refers to frequency modulation, which is a method of encoding information on a carrier wave by varying the frequency of the wave.

FM chord guitar is a musical concept, while FM is a technical concept related to radio transmission. **
