I'm doing ear training to identify chord progressions. I don't have problem playing a melody by ear. my goal is to play chords by ear and recognize them in different songs. To this day, I've already learned to identify I IV V triads. When hearing the progression I-IV-V, I sing it with solfege syllables of the bass note as "DO FA SO", no matter what the key is I always use the same syllables "DO FA SO" (what's called "Moveable DO"),even for minor chords. In this way I remember the intervals between the bass notes and the whole sequence of chords. This is fairly easy for me and works pretty well!
But I would like to advance with some more harmonic degrees (more progressions) and I came into a problem: Let's say I hear the progression I-vi-IV-V. I want to memorize it .How do I vocalize this sequence of chords? what is the best way? Should I sing "DO LA FA SO"? how to emphasize that "LA" is "LA minor" . Another example: The progression I-vi-ii-V, should I sing "DO LA RE SO"? or is there any better way to do this?
Another problem is: How do I stress the function of the chord while singing? meaning: I know that vi is similar to the tonic I, and ii is similar to IV , How can I emphasize this principle while memorizing the progression...
On the other way .If it's not possible to really sing chord progressions, How should I hear the progression in my inner mind, should I just remember how it sounds (seems difficult) or can I assign to each chord a musical name that will remind me the chord or the sound of it. but which "names" should I use?
I saw in another questions that there are some who pronounce the numbers, does it mean to sing the numbers and is it a better method ? How can one actually do that?
I have saw the question How to use solfege for chords? but it doesn't answer clearly what to do and how to really memorize progressions of chords....
I would like to have detailed instructions for what actually do. how to memorize the progressions and use them later for playing chords by ear or recognizing them in different songs. That's an information that I didn't find in this site or in the free internet. If I were a student at a music school, what would they teach me to do? I'm looking for a detailed practical guide.
