Why does the iii chord seem to be usually avoided in many styles?

I'll go a slightly different direction with my answer and say that I think this is a misconception. And frankly, I blame lackluster textbooks for it. I recall Kostka/Payne's Tonal Harmony in my ...

Opening of Bach's mass in b minor: why does it make sense?

Structurally, the second chord is not a C♯ half-diminished seventh but an A♯ diminished seventh in first inversion. The B in the second soprano is a suspension. The harmonic rhythm is in half notes ...

How is augmented major seventh chord functioning? (Gadd9/B Ebmaj7#5/B Cadd9)

It's actually a very common chord progression, but disguised by the spelling. The progression G G+ C — or, more generally, I I+ IV — is a frequent way to move chromatically from a I chord to a IV ...

Whenever you encounter a non-diatonic chord, it's worth checking if it's a modal interchange or a secondary chord. And perhaps also trying enharmonic spelling variations. G# and A# could be rewritten ...

how to replace the diminished chord in a key to write a good song without a diminished chord (for example e diminished to F)?
