I'm learning walking bass on the piano. All the walking bass guides I have say to play some approach tone on the last beat before a chord change.
If the progression were C to G you might play F# or Ab to approach the G of the G chord. But the common tone G would not be used. (At least the guidelines rule it out.) So, for example, | C C E G | G... wouldn't be used. Apparently the repeated common tone is too static.
My question is also prompted from another answer I got about walking bass recommending against repeated tones. But I don't put much stock in that person's advice as they weren't able to answer that question.
But does the same sensibility hold if the progression were C to E7 and the common tone E? When the change is a chromatic mediant like that, it seems to be repeating the common tone works differently. I suppose you could say the change is already so dynamic - all tones change but the E - that repeating the E in the bass provides some needed stability.
But I'm not really interested in the theory explanation. I just want to know if a jazz bassist would consider it a good walking bass or something to avoid?
