Okay so my friend has been playing guitar and bass for 6-7 years. he's very good. I've been playing bass for a few months. I'm okay I guess. He gives me lessons. I can play some songs. Black Magic Woman by Santana. What It Is and What Should Never Be, The Ocean, Rock n Roll, Dazed and Confused, by Zeppelin. Me and My Friends, Mellowship Slinky, Naked in The Rain, Can't Stop, Suck My Kiss, My Lovely Man, The Righteous and The Wicked by RHCP. A few others but not much else. But the thing is a lot of the times when he's giving me a lesson he'll say stuff like "put some bounce in it man" or "play it with a little heart!" I really don't know what he means. I just don't understand how to put bounce in it. I don't really know what i'm asking but i'm hoping someone here can help me.
