The 72-year-old musician, however, says the analytical approach is useful when it comes to dealing with other aspects of life, reports Financial Times newspaper.
"I don't intellectualise music. For me that spoils it, if I'm trying to analyse it and break it all down. It takes away whatever you connect with.
"I'm intellectual in my approach to a lot of other things, but not music. I'm a Virgo and Virgos have analytical minds. But I have to leave that behind with music, because it doesn't work for me," says Morrison.
"The teenage thing is another myth. It wasn't just that we were teenagers who loved this music. We liked it all our lives. I like it just as much now as I did then, sometimes even more. Our heroes were not people in the top 10. They were black guys who were much older.
"I still like Little Walter as much as I liked him then. Maybe even more," he says.
