Playing the harmonica seems to me to be one of the more difficult instruments I've taken on.
At this point, you are either going, "That's absolutely ridiculous!", or, "Certainly is!"
My difficulty comes not from learning the mechanics of the instrument but rather it's about exactly how to make my harmonica sound unique to me. I would say, due to its simplicity, the harmonica lends itself to simple, rather straight ahead playing which is as much as you get from many experiences with harmonica players. It's almost something to do while their not playing the guitar. Only a small group of players can turn their playing into something that leaves the listener amazed at what they have just perceived. Not in terms of, say, a fast and furious flurry of notes but in the expression of possibly a handful of perfectly phrased notes.
IMO, plenty of people can play the harmonica yet it takes the skills and imagination of a few to turn the instrument into something special. As I listen to the various players, particularly in the blues/roots traditions, I hear some who simply seem to be using the harmonica to fill time. Then every now and again I hear someone who makes my ears prick up and my heart break with their stylistic approach to playing such a simple instrument.
Every lesson I read regarding harmonica playing is about the mechanics of the instrument, not about pulling emotion from the playing. They may play a recording of a great player for me but they do little to explain what that player is (possibly) thinking or reaching for which turns their performance into something special.
Agree? Or, disagree?
