Welcome to the forums Innadi! I will assume from your question you have never taken a bass lesson with an experienced teacher? Sign up for a few lessons and learn how to tune your bass, where to put your hands, where the notes are located on the fretboard, how to make a pleasing sound on the instrument, what is the musical function of the bass line, etc. If there are no teachers where you live, we have some here on TalkBass who teach long-distance using Skype.
