I am studying a guitar piece where an F# minor chord is spelled as
F# / C# / A (R / P5 / m3) over strings 5, 3 and 2.
I found out that chords spanning over more than a octave are called open chords (not in the guitar open string sense of course).
For triads, this is the only possible open position of course, but with sevenths for instance there are more permutations possible, respectively 3 and 5 on top.
Is there a way to notate that like for close chords inversions (e.g. 6/3, 6/4)?
