So I have seen the blues progression below called "Basie Blues"
One basic method I have for walking bass says play the root on beat 1, any chord tone on beats 2 and 3, and then approach the next chord root by half-step. The second method shows walking bass by scale ascending and descending for the progression ii7-V7-Imaj7.
When I try applying these methods to IV7 - #iv dim7 - I7 the results don't sound right to me. I tried a simpler arpeggiation |Bb D F Bb|B B D F|F A C C#| and that sounds ok, but it's not really the method given above.
I also tried just playing the roots |Bb Bb Bb Bb|B B B B|F... |. That produces a tritone from bars 6 to 7. Is that considered bad for this style? To avoid the tritone I tried |Bb Bb Bb Bb| B B B B|C F A...| but I get the fifth on beat one. Problem?
Can anyone offer advice or typical patterns to use? I'm just beginning to learn blues/jazz piano.
Also, keep in mind I'm playing piano not string bass, and I don't know if there are unique approaches for piano.
I accepted an answer so I won't answer my own question, but I will add this bass transcription of 'H and T Blues' which is essentially the Basie Blues progression. Note that the bar 7 chord is written with slash notation to show that the 2nd inversion is used. That matches @StevesOnBass's answer, but I like having a transcript from a great player.
And for good measure, another from Walter Page, Lady Be Good...
...the problem with finding these was that I was looking only for things titles "Basie Blues."
