Bassist uninvolved in our songwriting
Currently having any issue in my band about my bassist not being a part of our songwriting process
I'm in a punk/hardcore band that's existed for almost a year now with a demo and an EP out. Well, I (drums) want our band to be punk, but my bandmates (guitarist, bassist, vocalist) are hardcore kids. But that's besides the point.
Usually at practice our bassist will just drop out when the guitarist and I sync up. The guitarist and I have good synergy together and can "just play," but this is something our bassist seems to not have.
I am also concerned that she never brings riffs to the band, and individually practices somewhat rarely. They get upset when our guitarist writes the basslines for them, but doesn't take an active role in trying to make them on their own to avoid this. I also don't think that the two of us have gone to the practice space together and jammed just bass and drums. I am not sure if they even could.
What are some ways I can approach this conversation with them/the band?
