How do you get the subdominant counter-chord of F-sharp major?
Good day,
This chord is supposed to be the subdominant antiphonal of F-sharp major. But I wonder how that could even be, since the subdominant in this case is B major, and its antiphonal would therefore be E-flat minor, right?
If the location is in A major, then the F#7 visual sound shown would already be correctly analyzed (green marked) as an intermediate dominant to the 2nd stage (Hm).
What is an interdominant? And then is the statement that the chord is the subdominant counter sound of Fis major?
If A Dur is the tonic, the Subdominant D major. The moll sound of a dur-three sound is a great terz higher, so fis-moll is the counter sound of D major. When the terz is increased, we get the digested subdominant-genklang Fis-Dur. In addition, however, a small sepitime (dominantseptim) is contained in the chord, which is why the interpretation as an intermediate dominant to the subdominant parallals h-moll (small terz deeper than D major) is the only correct one.
Part 1: see Wikipedia.
Part 2: No. The subdominant counter sound of Fis major would be D#m. But we’re not in Fis major anyway.
Or should you be aware that the chord has been changed?
Addendum: Yes we are in A major as suspected is the A major Prelude of Chopin, almost overlooked 🙂
Yes, the piece is beautiful and harmonious!
Okay, thank you. So it’s just the second stage?
So, with F# is Fis major 🙂 . Should I just write below in brackets under the 2 intermediate dominance?
No. As mentioned, F#7 is the intermediate dome to the 2nd stage.
