After becoming completely swept away by the quantity and quality of the replies here, I have been forming some new (for me) thoughts about all of this.
There are a few main aspects I have been thinking about, but first let me say that, there are too many things dancing around in my head, which people have posted about, for me to be able to give everyone the recognition they deserve. I just have to get some of these thoughts out...
1. I suppose there to be a difference between the "spirit" or "essence" of a piece and the "letter". (Yes, I am borrowing that expression from the Biblical connotations... please forgive if it offends, but I don't know how else to explain my thoughts) I suppose it is so with music in general....
A couple of aspects which strike me along these lines are as follows:
a) I think it is acceptable by most that "the letter" of a piece (what a composer puts down in ink on paper) does not change over time (unless the composer changes it), more or less. What the composer decided on as "the letter" can become somewhat set in stone. I suppose within this alone, there are many aspects and facets worth being addressed.
b) The "spirit" or "essence" could conceivably change, however, over time. Where is that contained exactly? Maybe within each of us. Perhaps the essence of a work or of music or of art, is indeed
meant to change, evolve and grow, or perhaps more accurately... teach
us how to do these things. I suppose this to be an endless process (if it could be labled as such).
Perhaps people spend more time arguing over the letter of a word and forgetting about or not recognizing the essence? Or perhaps it is the essence which is argued over, or maybe it is both. Whatever the case, there seems to be not much resolution with this yet...
2. About the source of it (art, music, etc) ... I have decided that it makes sense to me that it all comes from the same place (more or less). and with that...
3. About interpretation : I suppose the composer is already interpreting "the essence", and as a result, along comes the letter. It may be something mathematical, emotional, sexual, spiritual, nature-oirented (if there is a difference between all of these) or whatever else. Whatever the case, I suppose the letter should only serve the essence/spirit and should never aim to encapsulate it (it is impossible, it would seem).
What is striking me at the moment is this here (as an example):
Ingredients of a Well-Played Two Part Invention
https://pianoforum.net/smf/index.php/topic,4736.msg44774.html#msg44774(how to play inventions – Escher picture – Example: Invention 4 – Analogy with the game of chess)
It dawns on me that, there is an
essence about this piece of work (the Escher drawing) which is similar to that of a Bach's invention. Perhaps this is exactly what Bernhard is meaning by his words here: "A two voice invention is the sound equivalent of this visual ambiguity." (I do not mean to twist your words around nor put words into your mouth).
I would think, both Escher and JS Bach caught the wind of a similar essence and they were moved to interpret this through articulatin within their respective "chosen" "letter". I suppose the list of possible interpretations of this very essence can go on and on... mathematical relationships, chess, poetry, etc. I would decide that the composer or artist or poet etc. are moved by the same "spirit" or essence, which cannot be articulated or "passed along" from one person to another but through some medium of art (which could be as simple as looking into somebody's eyes or a heart-felt smile).
I would suppose the bird's flight to be a form of artistic interpretation of a deeply embedded
essence of life, which could be whispered to the onlooker, which "could be articulated" through the onlooker's medium of choice. What is that essence? Perhaps better questions for my mind, regarding life and music are "what is the essence of..." vs "what is life/music".
Perhaps I am only stating what is
the obvious to many of you whom are more advanced than I, but I want to sort these thoughts out and make them "my own". Through reading this thread, I glimpsed a view about art in general which moved my thought into new and exciting channels and directions. One of the most important things I realized is that art is not static. It does not stay nor even rest (perhaps) within the paper and ink... it is moving and breathing right along with us. It is formless and glowing and beautiful and is capable of bending the beholder's thought toward it's meaning (whatever that may be).
I suppose my goal as the performer is to first capture the essence of a piece and then work to articulate it.
Okay, I am out of words for now... thank you so much everyone for all of your replies
