Could you tell me at what level the dominant seventh chord is built? Beginning solfegists sometimes ask me this question. How can you not give me a hint? After all, for a musician this question is like something out of a catechism.
By the way, are you familiar with the word catechism? Catechism is an ancient Greek word, which in the modern sense means a summary of any teaching (for example, religious) in the form of questions and answers. This article also represents a range of questions and answers to them. We will figure out at what stage D2 is built, and at which D65.
At what stage is D7 built?
D7 is a dominant seventh chord, it is built on the fifth degree and consists of four sounds arranged in thirds. For example, in C major these sounds will be:
At what stage is D65 built?

At what stage is D2 built?

In general, it would be nice to have a cheat sheet, by looking at which you could immediately see where each chord is built. Here is a sign for you, copy it into your notebook and then you will always have it at hand.
