How do you notate a chord like G F A C E without using slash notation? G13sus? G13sus4?
Either would work. "sus" is typically interpreted as sus4.
Someone could interpret it as sus2. Someone else could add the fifth: D. But that's the fun with interpreting the chord symbols.
G11sus or G11sus4
These two symbols don't make sense to me. "11" means: add 11 (and b7, and perhaps even 9), while "sus4" means: replace 3 with 4 – that's contradictory.
After all, the only difference between that [G13sus4] and the G11 is the omitted third.
But that's a huge difference! So large, that – as Richard points out – many musicians wouldn't even consider to play a chord with both major third and 11 and play sus4 if they see 11 symbol. I'd like to add that some other musicians see sus4 as a coexistence of third and fourth. But it's a clearly very distinct sound.
In a major and dominant chords the perfect fourth is often called an avoid note, i.e. a note that even if it's present in the scale, shouldn't be emphasized. Playing a note as a part of the chord does emphasize it.
Why would you notate it without slash notation? F△/G seems very much the clearest way of expressing it.
I agree it's a very clear way to notate the chord, I would argue, even more clear than G13sus4:
- it strongly suggests to play notes G F A C E
- it strongly suggests to play G in the bass (which is not suggested by G13sus4)
The only issue that I may have with F△/G is that it suggests that the root of the chord is F, which means it's a fourth inversion of a ninth chord... which doesn't really exist, see e.g.:
How do you write a dominant ninth in fourth inversion?
What I mean by this is that in most cases we wouldn't hear this chord as rooted in F.
So the symbol F△/G isn't so helpful in understanding the harmony. But for writing a readable score for the performers it seems fine to me.
