2 sharps: F#, C# identifies D major and B minor

  • The major key is D major and the relative natural minor is B minor. They share exactly the same set of notes.
  • Scale notes in order: D, E, F#, G, A, B, C#.
  • Accidentals appear on the staff in this order: F# - C#.
  • Circle of fifths: 2 steps clockwise from C.

Next stepThe natural minor uses the same key signature as its relative major. For harmonic or melodic minor, raise the 7th (and also the 6th for melodic) when ascending.
