So what makes you like music that much, do you like it over other art forms?
This thread combined with your other reads like a homework assignment, heh.
How can you explain something subjective? I'll do my best. Warning, stream of consciousness follows.
I prefer music to static visual art for the simple reason that I can't close my eyes and get lost in a painting or a building or a drawing. Music stimulates my brain as I focus on all the different parts that make it come together. One could argue that looking at the different colors in a painting does something similar but it's a much more scaled back version of what I'm talking about. I can isolate the drums and listen to interesting cymbal work or how the bass player decides to contribute to the rhythm of a song. I can appreciate each instrument individually but the combination of them is what drives the desire to keep listening. I like hearing what is unsaid by the music, the notes that AREN'T played; filling in the gaps in my head. The implied notes. I like hearing the overtones and the harmonies and the intricate details just as much as I like hearing the final product without such analytical focus. I like hearing what isn't there.
Making music is the real drive and almost for a contradictory reason. While I like listening to something to stimulate my brain, I like being able to disconnect from that thought process while making music and not focus so much on the details. It comes out naturally in this way, when you're not thinking about anything but that moment. It is the only way that I know of that I feel connected to multiple people on the same wavelength. I feel connected to everyone else who is playing at the moment, like we all sense this unspoken idea or sound independently but also experience it knowingly together as if with an implied wink. The people in the audience who are listening.. are they feeling the same things? At that moment, when you look out into the crowd and see someone's head following the same unwritten rhythm you are... that can't be defined with words, that is how I feel most connected to everything around me. That intangible feeling is when I am at my happiest.
Sometimes I will listen to a show I've played later (I do all improv live) and wonder where the hell that idea came from? Is that me playing? Really? That's not at all what I remember playing. I love that retrospect. I love that it's so raw in that moment that I can't even remember it, the music stops mattering at that moment and the connection to others around me and the disconnection from time is the most rewarding feeling ever.
It's a lot like watching a well put together film. There are details there if you want them, if not, they do not spoil the outcome. If you notice them and want them, they contribute to the overall enjoyment more. Film is very similar to music for me because it is made up of a lot of different elements that you can study independently or watch as a whole. The framing of a shot, the lighting, the color choice. Is it symbolic in a way? Is it a nod to something else? Is it subconscious? Is it dumb luck? Your brain draws all these connections to fill in the spaces. Whether or not it's actually there to be found or a fabrication of your brain is an interesting concept to me. What is the artist saying versus what are they not saying?
Good musicians tell a story with their lyrics. Sometimes these ideas cannot be just written down or explained. It is another layer to the equation. Music describes what words usually fail to. I like a lot of abstract lyrics.. ones where if you read them you'd think it was a string of disconnected thoughts, but combined with the music that is going on at that moment, draws a much deeper focus and a much more real feeling out of the listener. It asks questions like, have I been where he/she is before? Have I felt this? Can I relate to that emotion? If you can, the music takes on a whole new meaning to you. It becomes a form of audible catharsis. It heals you in a way to listen to it. It also works in reverse though, it can bring up a pained memory or experience, it can make you feel depressed, it can humble you. Sometimes writing a song about how you feel is the only way to bring closure to whatever it is for me. You can listen to it later and remember and grow from it. I also can find this same appreciation with instrumental music, it doesn't have to have words to be meaningful. In that way, I can make my own assumptions about the message of the music, I can make it relate to me specifically. It becomes yours to do what you want with.
I know that most people do not experience these feelings in quite the same way I do, and that's ok. I hope that you can feel that strongly or deeply about something in your life in any other medium.
