In the older thread that @Mark_Johnson references, there’s an interesting example that caught my eye:
I would actually say that it’s poorly done. The alternate Db7 is (correctly) written in smaller size, parenthesized, shifted up. I would much prefer to see:
(C7 Db7 C7)
C7
in bars 1–3, 5–7, and 9–11. It obviates the need for repeat symbols, which to my eye just clutter things up and possibly even confuse the reader. And in this instance, to be really clear, I think the “main” C7 should be reiterated in bars 5 and 9 (perhaps in parentheses?).
(I also think this is a case where casting off four bars to a system would be helpful, though I realize that the RBs are trying to cram a lot of music in.)
Thoughts? I really appreciate @Mark_Johnson 's observation about harmonic-pattern repeats. I’m always — as an occasional jazz piano player — thinking about what will be visually clearest on the bandstand, which for me, in a case like Tizol’s tune, includes communicating 4-bar phrase organization.
