I was reading a theory book few days ago and I saw that F/C is a Hybrid chord of C .But how ?? I could under stand if it's G/C or Dm/C but isn't F/C just a inverstion ??

  • I don't know about this "hybrid chord" business, but if F is the root, then it is an **F** in 2nd inversion (e.g. **Gm7/D - C7 - F/C**), and if C is the root then it is a **C6(sus4)** (e.g. **Dm7 - G7 - F/C - C**). –  Mar 22 '18 at 05:41
  • @DavidBowling what do you mean by in the root ? Are you talking about the bass note ?? You gave me 2 examples and I they kinda look the same. Could you explain it more clear ? Thanks – Hyun Yoo Park Mar 22 '18 at 10:57
  • The root of the chord. C is the root of a C major triad, even if it is a **C/G** (2nd inversion). The point of the examples was that in the first one **F/C** is functioning as an **F** chord in the context of the chord progression, but in the second one **F/C** is functioning as a **C** chord in the context of the progression. In other words, **F/C** can function as an **F** in 2nd inversion, or it can function as a **C6(sus4)**, depending on the context. –  Mar 22 '18 at 13:32

    It might help if you could quote the definition of a hybrid chord that appears **in your music theory book**. There are at least a couple different definitions for hybrid chord online, so it’s not well defined. If we see what’s in the book it would help us understand the logic. – Todd Wilcox Mar 22 '18 at 14:50
  • @DavidBowling Oh I see ! Thanks for the answer ! So I think the answer is it depends on the context of the chord progression ! Thanks it really helped me out ! – Hyun Yoo Park Mar 22 '18 at 17:33

Hybrid chord of C? It's written F/C so it's an F chord with a C bass - a second inversion.

Maybe C/F would be a 'hybrid' of C, but when it's a slash chord,and the note after the slash, played as the lowest note, is part of the main chord, it's an inversion.

    Yes I understand what your saying.But from my book it says that F/C could also be a Hybrid of C.Maybe because we could see as Csus4 6 ?? And isn't C/F hybrid of F ? Because the bass note is the original chord in Hybrid chords ? – Hyun Yoo Park Mar 22 '18 at 10:50

I think it must just be a misprint. F/C is F major in 2nd inversion.

C/F would be a hybrid chord, C+4 (4th in bass).
