fretless
I'd like to give you some ideas about the very special instrumet called 'fretless bass'.
It is NOT just a bass guitar without frets but it's a special kind to express yourself.
Your hands are the most important tools to control in what way the tone swells, fills the room and decay.
Your hand decides if you are in tune or a out of tune. You can slide all the way up your "fretboard" in any speed you
like. You are not limited by those metal grids called frets :)
BUT that's the reason why most people think that playing a fretless bass is very difficult. They are afraid of missing
the correct intonation.
