Major and minor cords? Scales? Harmonics? Ive been playing bass for two months now and have been learning from song tabs, but when I search the forum I have no idea what any of these things are. Obviously I have never had any proper training :D . Anyone want to enlighten me/ have a guide for all this stuff? :help:

It would be kinda hard to explain what the scales and chords are without first learning what intervals are. If you want to learn, I suggest getting a book called Bass Fretboard Basics.
Also, take lessons.
