LOL, the beginner has this to worry about regardless of how many strings his bass has. What that beginner won't have to do later is revisit those same issues (tho minimized to some small degree) somewhere down the road when he does eventually try a fiver.
That's what we should be encouraging him to avoid.
I can't imagine telling a beginning pianist to use a 64 or 76-key instrument or a guitarist to use only five of his strings. Not a perfect analogy, I know, but it fits perfectly as a response to those who see the fiver or sixer as "extra" rather than "a bass". It's a bass. Not "another bass", or a "different" bass, or an "extended range" bass. All those terms are used only when we continue to standardize the four-stringer.
I posted this in a thread a while back. It applies here.
From
Bass Player's Anthony Jackson Interview, part 1:
My feeling is: Why is four the standard and not six? As the lowest-pitched member of the guitar family, the instrument should have had six strings from the beginning. The only reason it had four was because Leo Fender was thinking in application terms of an upright bass, but he built it along guitar lines because that was his training. The logical conception for the bass guitar encompasses six strings. As regards the issue of "mastering the 4-string" before moving on to the six, consider that inasmuch as there is no point where one can be said to have "mastered" anything, to make this inane suggestion reveals the speakers to be idiots. As long as we remain seekers, never truly achieving our ultimate goals, we may as well start with the full basic blueprint and enjoy the expanded expressive possibilities of the extended range of the instrument. Of course, the undoubtedly famous-name superstars who utter this nonsense probably regard themselves as masters in their own right. So be it. For the rest of us, their attitude reveals them to be jealous, angry, and frustrated. Too damn bad.
Can't say it any better than this.
Both of you already know that nothing is comfortable for a beginner, and few things are more difficult to get an experienced player to do than relive his old mistakes because he started on an instrument that didn't have six (or even five) strings. How many posts has either of you read where someone said they play a four because they "just can't get comfortable" on a fiver or sixer? That kind of thing had to happen earlier because of the way Leo designed the bass. Now it's completely avoidable.
It's. A. Bass.
