I just need a yes or no to clarify this:
Bb/E-Ab-Bb-Db = Half diminished Bb chord?
Now for a question,
How do I notate a Bb half diminshed?
Yes, that's a Bb half-diminished chord. To see it more clearly, u would have to rename the E to Fb.
Notation for any half-diminished chord = m7(b5)
So, Bb half-diminished chord = Bbm7(b5)
Would u like an explanation of why? I'll tell you anyway, LOL. The only thing that separates this chord from a m7 chord is that b5. Let's look at it:
m7 = 1-b3-
5-b7
half-dim or m7(b5) = 1-b3-
b5-b7
