whats the purpose of different string gauges?

[ShowKing]

ive always used medium lights 45-105 on my 4 string bass
and now i put on lights on my 5 string (45,65,80,100,125) today.
was wondering if theres more of a purpose for the different gauges.
eg. mayb if i play heavy rock music, do i need heavier gauge strings for that particular sound?

any input would be appreciated
thanks!

Many like a balanced feel and that's what I've noticed...
I prefer for:
45-105 45-65-85-105 4 string
Same for 5 with 130 for the B string
For 6 string 32 for the C string

Some don't notice or care.... I listen for punch and a solid feel to what I'm playing...

Different feel, different sound. Lighter strings are better for slap, chords. Heavier strings are easier to play fingerstyle. All IMHO ofcourse.

Also your left hand will be a lot happier with lighter strings.

does that mean lighter will produce more highs and heavier will produce more lows?

I use lighter gauge strings for my original band and heavier strings for my cover band. My tuning stays constant in my original band (standard) which is not the case in the cover band. I find that heavier gauge strings will last longer if you are constantly changing the tunings.

It also has to do with tension relative to the tuning.

I find lighter is more comfortable (easier even) and heavier has a warmer and in some cases.. well, heavier sound.

I use lighter gauges on my softer wood bodies. The "E" gets eaten up by some of them when it's above .100. Just thump without much sustain or timbre.
