Getting there! #74 probably goes too far in the other direction; I feel like now it's losing the strong look of
#49.
I like the new "M" and the new "h", though! The "M" reminds me of two fingers making a chord on a guitar. I think you also might have misunderstood what I meant about the "i" dot: it can be like the third note here:

Here are my other suggestions:
* The simpler clef was better (abstract is good); maybe go back to that but change either the bottom tail, or the dash of the "e"? I don't know what to recommend here, but in the new one the "e" is not as clear.
* The 5 lines top/bottom should align with the circle of the "e", then all the (large) lowercase letters (like in #50). Those letter could even be larger. The lines don't have to run all the way through, but that should line up.
Also please make ask more questions if needed, or suggest other things! I don't have a perfect idea in my head, so let me know if I'm just confusing things.... Thank you!
