Technically speaking, D sharp major is:
D#, E#, F* (F double Sharp,) G#, A#, B#, C* (C double sharp) D#.
***note: a double sharp (*) means that the note sounds a whole step above the principal note. For example: F*=G.
The D Major scale has two sharps, F and C. The notes in this scale are D, E F sharp, G, A, B, C sharp, D.
it has a C sharp but no D natural
D major has two sharps
G major, D major, E major, B major, F sharp major, F sharp minor, A sharp major, etc.
The major scale with 2 sharps is D major, they are F and C sharp.
The D Major scale has two sharps, F and C. The notes in this scale are D, E F sharp, G, A, B, C sharp, D.
E to F-sharp is one whole step. F-sharp is a major 3rd above D, so it's part of the D major scale.
D major isn't actually a note. D major is a major scale based on the note D (D natural) and the scale has two sharps (F sharp and C sharp). There isn't anything special about D major since it requires both an F sharp and a C sharp, the most 'special' scale is C major since there are no flats or sharps needed.
it has a C sharp but no D natural
D major has two sharps
G major, D major, E major, B major, F sharp major, F sharp minor, A sharp major, etc.
The major scale with 2 sharps is D major, they are F and C sharp.
The interval from F sharp to D sharp is a major sixth. In terms of scale degrees, F sharp to D sharp spans nine half steps. This interval can also be described as the distance between the first and sixth notes of the F sharp major scale.
F sharp C sharp G sharp D sharp
The dominant (fifth) degree of a D sharp major scale is A sharp.
A, B, C sharp, D, E, F sharp, G sharp, A
There are different rules. For major keys, the rule is this (by the way, # means sharp): C major scale- 0 sharps or flats G major scale- 1 sharp - F sharp D major scale- 2 sharps - F and C sharp A major scale- 3 sharps - F, C, G sharp E major scale- 4 sharps - F, C, G, D sharp B major scale- 5 sharps - F, C, G, D, A sharp F# major scale- 6 sharps - F, C, G, D, A, E sharp C# major scale - 7 sharps - F, C, G, D, A, E, B sharp. For major keys with flats: F major scale - 1 flat - B flat B flat major scale - 2 flats - B, E flat E flat major scale - 3 flats - B, E, A flat A flat major scale - 4 flats - B, E, A, D flat D flat major scale - 5 flats - B, E, A, D, G flat G flat major scale - 6 flats - B, E, A, D, G, C flat C flat major scale - 7 flats - B, E, A, D, G, C, F flat So as you might have noticed, in increasing order of sharps it is: F, C, G, D, A, E, B. And the increasing order of flats is B, E, A, D, G, C, F. If you notice the order of sharps is the opposite of the order of flats.
