Years ago before my tail above. I answered an ad for an original music band. I asked what kind of music it was it be. They say its "original" music and can't describe it, I'll just have to hear it.
So I go by and they are all happy friendly people ready to show me their "original" music. They take off on one of their numbers, telling me if I can pick it up to join in but I probably wont get it, cause it's "original."
So I listen to what they got, it's a blues waltz. I don't know what the lyrics are about but it's blues chord changes in 3/4 time. So, I play along, in key and tempo. Fine no trouble at all. So the next one they show me the chords, it's in a different key but again 1-4-5 changes, so they ask if I need some time to absorb what they just showed me? I say no, lets go! I play it, thought I nailed it. The next one was more blues changes only minor this time. I play it and ask if they need me to play some fixed "original" bass patterns they had or if they were looking for something particular from me to play? They indicated what I was doing was fine but I could sense some tension in the room. We did a few more and called it a night.
Two days later I get the call that it won't work out. I asked if I didn't perform their songs well enough? No that wasn't it, it was they felt I didn't give their "original" songs the reverence they were due. I jumped in and played them without having trouble playing them or holding back in awe, because these were their "original" songs and I was playing them like they were common songs.
I tried to explain to them they were fine songs just that those chords changes are common but that's not to take away from their original melodies and lyrics. I immediately get "What do you mean common chord changes?" Oh no!
I try to explain a 1-4-5 chord change is common in a lot of songs and that is why I was able to jump in and play along. I asked if they preferred me not being able to play along. These are "original" songs I was told and I shouldn't be able to play them that fast. I told them there is nothing wrong with basing original songs on known chord changes, it's done all the time. It seemed at that point the person dealing with me thought differently and rather than belabor the point as if I was trying for the bass chair, I said, that's fine.
But warned them you would have to look far and wide to find a bass player that couldn't recognize 1-4-5 changes and if you did, you may not want to work with them
