Regarding piano scales,are diminished sevenths and dominant sevenths the same thing?

The reason it is the same is because the true dominant chord always contains the leading tone. In C natural minor, for example, the natural dominant would contain the sub-tonic (Bb) as opposed to the leading tone (B natural). Without the leading tone, the dominant chord in C natural minor has the tendency to flow down to a sub-dominant chord, while a dominant chord containing the leading tone has a stronger pull towards the tonic chord.

The typical Dominant 7 consists of these intervals- Major third+Minor third+Minor third. That is the only true form of a Dominant 7.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
