Building on what these two pros have to say…
Rachel, it is my belief that given the right motives a person will relish in any situation you place them in. The real question is, do you have a passion for the sound a shamisen is capable of making?
Do you want to feel the instrument within your hands and listen to the endless music you can produce from it? Sure, novelty songs that you already like are fine and nice to learn when you first get started, but will they be enough alone to keep you interested in the instrument? At the end of the day, whether you are naturally gifted or not you must enjoy it.
I have wanted a shamisen for over a year and a half now. I have stalked these forums and this site many days before posting. I loved the Naruto tracks and one day it donged on me to find out what that awesome thwack was that would build momentum up before something cool happened, and again in an awesome tantrum during fight scenes.
But, after a while it wasn’t about the music tracks or being able to play bits and pieces, it simply became an obsession for me. In my opinion, it is like any other trend, you must test yourself and find out if it’s worth investing in. I knew because it would always loom in my mind, and the moment I forgot about wanting one something would jerk me back to the thought. If you ever find yourself fantasizing about it, then you might just need to invest in a shamisen.
Oh yes, and welcome! I recently received my first shamisen just yesterday, and I will tell ya what I need to go back to playing it before the night grows old, so sayonara!
