Music matters because it's exemplifies the need to know.
Music, like any language is a 'confrontation' and as such we have an innate desire to resolve it.
And because music is so much simpler than other languages (compare the number of notes to the number of words...what is the distinction of a single note? (Ask Pete Townshend...is that was Pure and Easy was about?...that a single note could actually be fully understood by all?)))

Any layman who has read Oliver Sacks' book "Musicophilia would say
音乐很重要。叔本华从坟墓里爬出来……

根据我对现代智人与前智人的痴迷:音乐是达尔文的“生存技能”吗?大胆地说，我说不!“音乐欣赏”可能是斯蒂芬·古尔德(Stephen Gould)在进化计划中的一个“标点”，这可能是一个很危险的想法，而且接近神创论(!!)。这意味着小提琴或海登(或随意填充)，是宇宙中最独特和特别了不起的。

One of the biggest mysteries of life to me is why should a series of sound frequencies evoke emotional responses in humans. One sequense is sad another happy and infinatly subtle differences in between. Why?

I am afraid I received notification about this program too late to hear it. Does anyone know when it will be available for download? .Is there any other place or way I can hear it?
I am feeling the resonance of the importance to me of the topic, but need to get to the source.

它可能不…你播放一个随机的声音频率序列，它的唯一反应是uuggh…就像任何不和谐或不熟悉的噪音一样。
我想说的是，这不是“音乐”本身，而是熟悉感。人们讨厌摇滚，但我认为那只是因为不熟悉，而不是因为音量(因为爵士、大乐队和任何让青少年“兴奋过度”的东西也是如此)。
You play someone a completely new kind of music for the first time it's strange...you play it 5x then it becomes familiar and has emotional impact (just like any input does, especially language)...then you play something similar and they get the pattern recognition going.

When we aren't just enjoying it, music is a truly baffling subject. One might be tempted to suggest that music arouses emotion by evoking associations. However, this doesn't explain how a piece of music can deeply effect someone on the first listen.

oh me goodness! why you all seriously analyze this subject. music is emotion. people dont create music because they are analytical. although the rational world wants you to believe it is. anyone who has been a musician knows that the most complecated piece is made beautiful by emotion, not technical perfection. wake up elitests!!!!!!!!!!!!!!!!!!!!1

An elegant geometry solution can be beautiful---
I have experienced the same thing being beautiful one day and not beautiful the next. That is, I have no sentiment that it is beautiful, whereas previously I had.
Let's bring the perception problem:
Assuming there is a split between the world and the mind--then hard to pin down whether a thing in the world
is beautiful or whether the mind sees the thing as beautiful--but there is no such quality to the thing.
Is something beautiful and at times we are in the
right frame of mind to see its beauty or is nothing either beautiful or not beautiful and we project the beauty onto the thing?
换句话说，美是否对应着一种情绪——即使是针对同一件物品，这种情绪也可能来来去去?
Or does beauty result from a combination of circumstances that may be unique and may or may not be reproducible?
If we posit that every opinion has emotional and non-emotional aspects---How much of opinion is emotion and how much not emotion? Is it better just to leave the issue undecided and just say that we have sentiments---one of which is that something is beautiful?
If beauty is in the eye of the beholder---then it seems anything can be beautiful. I remember seeing spray painted circles all over a tall building --the circles were made by painters to mark out places to be patched--prior to painting--- and I found the pattern beautiful.
But then, can a severed head be beautiful?
美和崇高之间古老的区别是有效的吗?May something be sublime
不美丽，反之亦然?
Debussy's piano piece, Claire de Lune, I find beautiful---but many parts of Stravinsky's Rite of Spring I do not--- but Rite has sublimity--a kind of overawing power----
Maybe sublimity is a sub-category of beauty
or beauty a type of sublimity?

I was disappointed with the discussion; there was no positive explanation of the power of music, just a tearing down of any possible reason to believe music is important, and that its effect on us is profound. It is easier to tear somethingh down than build something up, that is all this show "proves."

In response to Robert Sharp:
Why should there have been an explanation of "the power of music?" The topic is why music matters, i.e. reasons why music is important. Although, the power of music is a good topic to explore, so I will do so. What do you mean by "the power of music?" Are you referring to emotional, political, and/or political power? I can only readily agree that music has an artistic power (otherwise it wouldn't be an artform). Emotional power seems to be derived from a listener's associations and political power seems to be derived from a musician's ulterior motives. Any thoughts?
In response to the general discussion:
如果音乐仅仅是情感上的，那么与让我们体验类似于音乐所激发的情感的神经刺激装置相比，是什么让它成为艺术呢?其他的品质，如作曲也有作用吗?
