Can a cadence consist of a triad with only 2 different notes?
Let's say I'm in Fmaj
and want to include an imperfect cadence (ii - V
):
G - D - G
followed by C - E - G
. The first triad has only two different notes (G
and D
), is this possible?
EDIT:
My question arose because I'm doing an exercise that requires writing a short melody ending in an imperfect cadence in Fmaj
. I decided to use the ii-V
cadence with the chords shown above.
However, when I played the excerpt and finished with the "imperfect" cadence, it sounded a lot like a "perfect" cadence - the roots of the chords are G
and C
which are also in the perfect cadence in Cmaj
and all notes are also present in the Cmaj
scale. It certainly doesn't sound imperfect, which is why I was wondering if this would be allowed in music.
