It is a curious tendency, when talking about music, to regard it as an object or 'thing'. But is this really true? Perhaps it is necessary, in order to have some meaningful discussion about music, to think / speak like this. It may be beneficial to examine this assumption in detail, to understand what music actually 'is', and how it may be understood.
For instance, we often assume that there is a prevailing emotional content in some music, and that this will be evident to most who listen to it. This may be stated in different ways, but the idea is the same: the composer has recorded his thoughts or feelings in those sounds, and then we come along and listen to them, and are able to perceive these. This analogy implies that music is an object with perceivable properties (very scientific).
This idea tends to come undone when we realise that different people will understand the music in entirely different ways, and this is especially evident when people from other cultures are listening, or when we are listening to music from other cultures. What then becomes apparent is that the extra-musical content (emotions, etc) of some music is perceived according to the context of the listener. So there now seems to be nothing objective or absolute in the music itself.
How is it, then, that we can understand music at all? It must rely on the shared perception of people in a similar context, or on some instinctive / intuitive side of ourselves which defies elucidation. One doesn't need all this analysis to comprehend a Beethoven symphony, because the flow of ideas or emotions seems clear enough to those who can perceive it.
In this light it seems that music can draw attention to our perceptive processes and how they are used for understanding. By not being an object or 'thing' to be apprehended by the mind, music can defy that analytical tendency which makes distinguishing or dualistic judgements (this is this and that is that). In this manner it may show us a different level of understanding.
Perhaps it is useful to give these ideas some thought, and try to understand how our perceptual capabilities are enhanced or modified by listening to music. However poorly I have sketched out this idea, please add your thoughts, so we may learn something.
