What a ridiculous and subjective question. It is like asking what piece of art is the right art? To indicate that one bass tone is the right one fundamentally ties the hands of the musician, throws out a huge array of music styles and genres, and for all intents and purposes narrows the mind to a point where creativity is completely stifled. All you have to do is look at this member's Forum name to see that his mind is already closed to diversity. I would go so far as to throw out the term "Tone Racist".
Music should have no limits, borders, absolutes, or "rightness". The lack of rules in music is what makes it great.
