Great Topic!!
Here's my twist on this.. Has anyone on here heard of a composer named John Cage, or his work entitled 4'33" (four minutes, thirty-three seconds)? This work is arguably his MOST famous work. Sorry to ruin it for you if you haven't yet "heard" it, It is a solo piano work in which the pianist comes out, opens the piano, plays and does nothing for 4 minutes 33 seconds, then leaves and that is the piece. This piece in well known in the classical world though I do not know whether it is because of its originality or because of the idea it suggests. To me it means, even silence is music, the world we live in and every sound it makes can be music if you listen to it in that way. Every time it is performed, it will be different. One time, it could be the low frequency, gentle hum of an AC machine breifly interrupted by the sound of the freight elevator. Or it could be the sounds of people near to you breathing coupled with distant footsteps. Technically, I believe music is defined as some sound that is organized in some way, that the sounds are somehow related. I've studied music for nearly 14 years and still, this question is open. I don't think it is one that can ever be definitively answered.
As a response to the prior post about music conveying emotion, music ITSELF does not convey the emotion imo. Many people are brought up to believe that minor means sad and major means happy but when you think of this, humans have attached our emotions to it. The music itself knows no emotion. Now, it may seem that music conveys certain types of emotions but those are the things that we have grown up to know. Much of this is because of the the lyrics. There are not many popular bands or groups that do not use lyrics. imo, thats because people can connect with the song more when the lyrics write the feelings into it, its more clearly relatable than music alone.
Also, when you said "music uses pattern in order to communicate ideas or emotions with the listener", I don't think that is true either. The pattern thing, kinda, the goal of music, not so much. As in art, often the viewer (or in music's case, the listener) was not the goal of the creation of the piece. Many artists create art for art's sake, for themselves or just for more beauty in the world (the definition of beauty, though, is a whole nother ball of wax). The truest art comes from that place imo, not from serving an audience.
I hope I haven't offended you. I'm always interesed in having a good intellectual conversation about music
