It's all in the feel and how you connect more with your band member
Actually it's not just bass and the drums to coordinate together but more of the whole band as a whole.
If everybody follows each other with the groove ... doesn't matter whether it's just a casual jamming, doing an original or a cover ... your band will always be tight.
listening to each other and know what the others are playing is important to make your band tight.
As a bassist, i just play some groove and trust my drummer to groove the same ... or it works backwards ... doesnt matter
Just groove it
How do you achieve that? Jam more and practise more with your band members.
practice with your bandmates as often as possible, practice in complete darkness with your band so all of you can play blind, and adapt to changes on the fly (e.g. if your singer starts singing a phrase earlier than he's supposed to, everyone needs to adapt accordingly)
for my band, whatever happens, we'll follow the drummer. so, basicly, if the drummer go way too fast, one of us will have to tell to tell him or worst come to worstl, we'll have to follow him. one thing is practice together often.
hmmm, go on outings together that are not music related, e.g. eat lunch, go watch movies, go swimming, get to know your bandmates better, den u noe how they tick, den can manipulate...er i meant manage each other better
