With some careful
planning, you can solve most of your
conundrums with
pipelinking.
If your node is about Peter Jazzpianoplayer, you can make it into:
[avant-garde jazz piano|Peter Jazzpianoplayer]
This way, you're free to point people in more directions by linking to more relevant information. I'd personally guess a lot of folks wouldn't know what avant-garde meant, so I'd hardlink it as [avant-garde], but make sure that where you link it to is correct. If avant-garde is noded as avant garde with no hyphen, pipelink yours to [avant garde|avant-garde].
Now, with jazz piano, you can break it down into two related links:
[jazz] and [jazz piano|piano]
Now, you're sending them exactly where you want them to go to learn more about your specific topic.
