Hi folks, I wanted to ask you something I have been dealing with for as long as I have learned music theory: when is the point that you simply learn stuff by heart?
For example: I could not imagine writing out all keys in order to learn which notes a contained in them. But I learned all notes in all diatonic 7th chords by simply using flashcards. How am I to „practices“ my way into knowing what notes makes up a Dminor7?
Whats your experience with that? Where do you draw the line?
On the Piano i go from what i know and transpose the chord, until eventually it is just in my head. For the chords in major minor it is pretty straight forward. a major chord has the large third, as major has the half tone step between 3-4 and 7-8. the minor chord is half a tone lowet on the third because 2-3 and 5-6 are the half steps in minor. Since the fifth is identical in both, the 7 accord is one whole tone below the base tone. In case of the 7maj it is just a half step lower.
So a Dmin7 is D, F, A, C
A D7 is D, F#, A, C
On the piano it is easiest though, because you can see the ladder and transposing just needs to mov the fingers up or down a bit.
