My question is simple: Can a m7b5 chord be used instead of a dimished chord and vice verca?
The reason I am asking is because I saw another transcription of the same song and one had notated a m7b5 while the other transcription called for a diminished chord.
I know it's really trivial question from most of you probably but I would like to know which is the correct chord to use or both can be used.
Thank you in advance

Beginner questions can be more complex than they might at first appear.
As to the best answer can you do something in music, try it and decide for yourself if it works.
If the question it is has it done before, the answer is yes but it also more nuanced.
What is the context the diminished chord is being used?
I'll give two examples:
leading tone diminished.... Bo7 Cma6 || Bm7b5 Cma6
common tone diminished.... Co7 Cma6 || Cm7b5 Cma6
-
What's the melody note in relation to the chord?
-
F / / / Eo (or Em7b5) / A7 / Dm / / / C7 / F7 /
-
There must gut tells me Em7b5, because it's clearly part of a minor ii V i...
But what's the melody?
-
it should be. cause there is a natural D in the melody. right ?
-
Em7b5.
What's the tune? Feels familiar, but I'm not sure where we are starting from.

I'm sure you know it. Confirmation by Charlie parker

Ah...
Try Dm7 Dbm7 Cm7 F7 (2 beats each)at that point instead of a whole bar of Dm7 and the C7...

So you might play the triad in place of either chord, but not one chord in place of the other. If the melody is b7 or 6 you would play the corresponding chord as the other chord would clash with the melody.

Oh I see, thank you

But doesn't the line go: G D Bb G? That solidly outlines an Em7b5.
And, as Mr.B pointed out, the Em7b5 comes before an A7 which would make it the ii. That makes far more sense than Eo.
Are you mistaking the half-diminished symbol ø for the diminished sign o?

Simplest answer I can think of - dim7s and m7b5 aren’t ALWAYS interchangeable but can be in some cases.
I wonder what the source for Eo7 is?

Tassos is mucking about. He's raised the same issue on another thread AND had it answered.
It's an Em7b5 (of course). He got the half-dim sign and the o sign muddled. (As I wondered, to be immodest).

So wait, have we now figured out that the chord was never Edim7, but a misreading of the circle with a slash through it m7b5 symbol?

Since Eo is the triad E, G, Bb you’ve basically just dropped the 7th from Em7b5. I think it’s richer with the 7th, but sometimes it’s nice to leave things more open. Bottom line: I’d probably play Em7b5 there unless there’s some reason to drop the 7th.
By the way, if you had written Eo7 instead of Eo, I’d think of that as A7b9 with no root. But the next chord is A7, so Eo7 would seem a bit redundant.

It's also a lot simpler than that, as I said before. Look at the bleedin' lead sheet!
Never mind the chord, look at the notes: G D Bb G.
