We are in F sharp minor. There is a G sharp being held over V7 (Csharp7), the second inversion tonic chord (Fsharp minor), and then the ii7 chord that follows. The G sharp is a chord tone of both the V7 and the ii7, but it is the (suspended?) second of the tonic chord in the middle.
Is this a suspension? The G sharp is a perfect 5th above the bass note of the second inversion tonic chord, so does this mean that it is not a dissonance/ suspension? I don't think i have come across suspensions over second inversion chords yet.
So, what exactly is going on here, and how do I figure this?
Any help very gratefully received,
