Rhythm, Harmony, and Proportion

In modern architecture, there are always the unspoken rules on what is in proportion. When the design is not base on mathematical arrangement, how did architects/designers evaluate what is a good design?

In music, the variation of harmony can be distinguished by listening, or most obviously, while learning. There are different definitions of harmony. For example, Chopin way of putting harmony together is totally different than how Bach does. Chopin uses his harmony in a very rich way. In other words, every chord combination is perfect. His notes always look dense, his chord-spans are usually close to human extreme (same with Liszt and Rachmaninoff); therefore it looks difficult to learn. However, surprisingly, when learning his new piece, every moment is in harmony, you would know this chord is right without mis-reading from his dense notes. In this way, even though Chopin notes are looks much more complicated than Bach, learning his piece is easier since your ears instruct hands to learn this piece. It makes the learning process pleasant because the happiness of conquer appears right away. While for Bach, especially for fugue, piano learners can easily lose the patience of learning. The piece looks less dense than Chopin of course, but his harmony is in movement instead of solid chords; in other words, his harmony is delayed and elongated. There are hardly any harmonized moments, but phrase instead. Harmony in Baroque music is by alternating the theme rhythm in different period. Learning a Baroque piece is totally different than any other classical music. There are at least 2 lines themes, or even 7 themes performing together. It is the themes that compliment each other. Since it lacks of moments in Bach fugue, learning is always difficult. You might have already familiarized one hand playing 4 themes, but putting both hands together playing totally difference harmony and rhythm is very challenging.

I personally think Oslo Opera House can represent Chopin or Rachmaninoff. It is elegant, pure, harmonized. Its beauty appears in asymmetric balance, like Chinese calligraphy. The harmony of materials (dark blue glazing and white marble) represent glacier. I feel purified  when walk through the space, as well as playing Chopin. For Baroque music, I have found similarities with Zaha buildings. In her drawings, there are always repetition of elements appears in different moments, and they have relation with each other at some points. Interweaving and flowing together as a whole. I guess these harmonized drawings and also due to the fact that she listen to Bach while designing.
