While messing around on my MIDI keyboard i found that an interval of two semitones and then four semitones produces very interesting harmonies like eg: D-F-A# .I want to know the name of this harmony . I've looked into augmented , diminished chords but am not sure . Just need some pointers to do more research .

Well for starters, a chord made from stacking 2+4 semitones would be very different from D-F-A#. D-F-A# would be three semitones followed by 5 semitones, and as others have noted, is enharmonic to Bb maj 6/3. 2+4 would be like D-E-G#, which could be seen as a dominant 7th chord in 4/2 inversion. – NReilingh♦ Jan 27 at 23:49

I'd say D-F-A# is B flat major, first inversion, with a different spelling.

Maybe the music theory nerds among us might say it is a minor augmented chord or something, but it will sound exactly like B flat major.

There's a couple of ways to name that chord (D-F-A#):

  1. Bb major in first inversion, as mentioned in terpsichore's answer.

  2. Dm(aug), Dm+5 or Dm#5. Although there's no such thing as a minor augmented chord in music theory, in rare cases it might be useful to write it like this, for instance in a chord progression that requires a specific voicing.

  3. Dm6. In classical music, sixth chord used to mean the same thing as first inversion. However, in modern music theory that would be interpreted as a D minor triad with an added sixth, or D-F-A-B.
