I've hoping to be able to play an musical instrument for a very long time but for some reason that I cant do it as i like. well,now, i can have the chance to play some. but i found i have no idea about music because i never learn any about it…so where can i start from? and which one of bass and guitar is easier for me to start with? thank you so much!
If you learn guitar first, then bass is incredibly easy to learn afterwards.
If you want to start out with playing cover chords of popular songs, try http://www.youtube.com/user/yourguitarsage
But just learn some basic chord shapes, and how they are supposed to fit together, and practice a lot!
(and make sure you have a guitar :] )
