Hello, I posted a thread the other day about opinions on two bass models. I’m a veteran guitar player picking up a new bass, and one thing I noticed was how many people suggested that I buy a 4 string bass instead of a 5. I was a bit confused, because I was only asking about specific models, not whether to get a 4 or 5. Is there some stigma with 5 strings that I’m not aware of? I know everyone has opinions and I respect that, but I was surprised to see it pop up so much.
I wouldn't call it a stigma, I would call it tribal BS. People tend to hold the idea that their way if thinking is the best, and everyone should agree.
Here's my advice: If you want to play 5-string, then you should start on a 5-string. Why?
I started on 4-string and underwent two transitions. First I transitioned from 4-string to 5-string around 1992. Then around 1995 I transitioned from 5-string to 6-string. I would say it takes about two years to really transition to an extended range instrument. Why would you want to endure that? Also, I would say it took me about ten years to begin thinking more as a natural 6-string player, than like a 4-string player who had a few extra strings to deal with. If you know you want to play a 5-string, take the easiest path to becoming a natural 5-string player.
Here's the deal, when you are first learning to play, you have to learn the finger board. At first that takes a lot of concentration and focus to know where the notes are. Over time your mind builds a spatial map so you can play automatically without thinking. When you add a string, it confounds your automatic mental process, so you have to forget and relearn your automated mental map. This degrades your playing and is frustrating.
Also, a person who plays an extended range instrument will have different strategies for navigating the fretboard. As a 4-string player, you have to make lot's of shifts up and down the neck. As a 6-string player you can simply play across the strings. You can still shift if you like, but you have a choice that allows you options if you want a different tone or texture. When you are playing fast, technical music, you don't have time think about whether you will shift or play across the strings, you just play however is most natural. A natural 6-string player will feel a bit lost with a 4-string in his or her hands, due to the missing strings. If you have some fast technical music to play, you will probably have to stop and think about how you will navigate the fretboard.
If I were limited to five strings, I would keep the low-B for commercial music. I use the high C mainly for soloing over jazz standards. But believe it or not, when I was running a country band around 2000, some of the top 40 hits had bass fills that felt right on the C string. Quite a few of the hits had notes played on the low B string.
Some Advantages of the 5-string:
There is lot's of material that was written for the B-string or written for synthesizer that goes below the open E. Also it pretty common to have to transpose music down because the vocalist cannot cover some material in the original key. Sometimes transposing music can destroy an iconic bass line if you only have a 4-string bass, but if you have a low B string you can continue to play the original bass line.
A lot of people that tell you to play a 4-string have tried to transition to 5-string and failed. It's not an easy transition IMHO, so I think starting on 4-string with the idea of learning to play 5-string later is the wrong choice.
You already have a mental map of the lower four strings from playing guitar, so you are already in for a bit of an ordeal. If you are not committed to the task then I agree with the people who are telling you to play 4-string...you already have that 4-string map in order, so it's just a matter of learning the technique and how to play good bass lines.
Also normally I would say you need to play 5-string exclusively for an extended time. Playing a 4-string will reinforce your current mental map and continually confound the new 5-string map your are trying to develop. Since I expect you will continue playing guitar, this could complicate your ability to build and maintain a 5-string mental map. As an example, I have trouble keeping things straight between 6-string bass and 6-string guitar, especially C string VS B string.The only saving grace is you probably don't really think that much about low notes on guitar, so maybe it wont' be that bad.
Hope this helps explain some peoples' responses and gives you some context so you can make an informed decision. I really do think having access to that low B is incredibly useful for many styles of music. I own 4-strings, but I can't imagine a 4-string ever being my #1 again.
