If I listen to a Mozart piano sonata, I am practically unable to comprehend what is happening musically.
I'm talking about functional perception, hearing the function of each note or chord.
Sometimes as a phrase comes to an end I can make out the subdominant, the leading note and then the tonic. But it is like trying to watch a bluebottle. It may settle for a moment but it darts around faster than my eye can track it. As soon as I figure out where the buzz is coming from and put my eyes there, the bluebottle is somewhere else.
However, if I hear the melody of three blind mice, I can register the function of each note.
So, it should be possible to gradually ramp up the difficulty level!
Music is written to mystify the listener, so it goes in the opposite direction so a learning resource.
EDIT: I had better elaborate on that. Take any pop song, the harmony may be as basic as I vi IV V, but the lyrics, instruments, weaving melody tell a story that focuses the conscious attention of the listener elsewhere. Typically a listener doesn't hear the second measure and say to themselves "this is boring, it is just repeating itself" because they don't notice this repetition. Maybe like an Escher staircase, or a ball of clay that has been shaped into a dog, if you see the process from the beginning you're aware it is a ball of clay. But if you just see the end result it looks like a dog. Of course a well-trained musician is able to appreciate the underlying structure, but for a piece of classical music this basic structure gets twisted tweaked moulded ... until it is really hard to figure out what is going on musically.
Whatever scaffold was created initially gets rubbed out, a simple melody gets ornamented, a basic chord sequence gets extemporised upon, bass notes get erased, etc.
I could take a piece of classical music and simplify it repeatedly, maybe after 4 passes I will be left with the skeleton.
It strikes me that it would be a very valuable practice to start out with hearing such a skeleton, and only when I am able to fluently comprehend the musical content should I progress.
Usually I have but to think of something, and I can find it available from Googling.
I have been searching, expecting to find some 10 CD course, where the teacher is playing basic melodies and harmonies, of increasing complexity. And I can learn by picking out the melody or baseline solfege with my voice or on an instrument.
A simple melody harmonised with a single bass note every time the harmony changes -- this would be perfect. It seems like such a simple idea, surely some teacher has created such a resource.
But I cannot find such a thing! It's a difficult thing to search for.
So my question is, do there exist terms and phrases for this method of learning? Are there any resources in existence for teaching in this way? How might I go about finding them?
