Appreciating jazz is similar to appreciating any type of music. It dependes on your definition.
I used to play trumpet and was in a jazz band myself, although that was a long time ago. Now I'm lucky to recognize a trumpet 3 out of 4 times.
Does this background give me a grander appreciation and love of the genre? Maybe.
There are some people that can get immersed in some music who have never picked up an instrument in their lives. (Air drums do not count
) They don't understand or could care less about the technical aspects of the music. All they know is that the music touches them on an emotional level that they cannot describe.
Other people who have studied an instument or theory will have a greater
understanding of the music and the mechanics, but may not reach the emotional level as the untrained.
Who appreciates it more? You can answer that question on your own.
As far as trying to foster a love for a particular style of music, I would start with what you already enjoy. I'm assuming that you like blues since Led Zepplin, your avatar, relied heavily on its forms at times. Start with blues artists or jazz artists with a blues feel. Focus on artists who feature instruments which you enjoy the most. If there is a song on a disc that you especially like, figure out what makes it special to you and expand in that direction. Is it the great solo in the middle or the off-beat funky style of the rhythm section? Does it have a latin feel or is the vocalist's voice especially appealing? Once you start to understand what you do or do not like about jazz, then you can start to find your own personal niche within the genre. For example, I really like Miles Davis'
Kind of Blue and other early stuff. However, I cannot stand his later free form style. It's not that it is bad music; it's just not for me. By asking the knowledgable people on this forum and your
quality neighborhood music shop, you can be guided to artists that suit your tastes.
Remember, it is not listening to jazz that you dislike and forcing yourself to like it in order to "appreciate" jazz music, it is experimenting and finding the style within jazz that you connect to.
