imperfect cadences..?

Question

liiike you know.
I to V
IV to V
I 6 4 to V

[this is MUSIC aural/theory we're talking about]
yea this is for the grade 7 abrsm test.

so i don't really get. like which two notes are you comparing? i kinda get the one to five stuff, but i just need to know which two notes you're comparing.
and any helpful links are appreciated (=
kay thanks

so where does the I, IV, and I6/4 come from?
okok. I to V is five notes away. IV is one note away. I6/4 is the same note of an octave apart. so is "V" is the ending note? and where is the "I" coming from?

what do you need to listen to in order to determine if it is I, IV or I6/4?

Answer 1

An "imperfect cadence" (or half cadence, depending on your geographical location...) is simply a cadence that arrives on V. So, I-V would work, ii6/5-V would work, IV-V would work. The so-called "I6/4"-V would work, too...although I take issue with it being called I6/4, but that's a topic for another thread...

I don't know what you mean when you ask "which two notes are you comparing?" It's not a matter of comparing any notes, just seeing that the phrase arrives on the dominant harmony. And, of course, this will usually be at the end of an antecedent phrase, which will be followed by the consequent phrase, in which the cadence will finally get back to tonic.

Hope this helps!

Answer 2

Those Roman numerals correspond to scale tones.

I is a major chord with its root built on the first scale degree -- in the key of C, then, built on C

V would be a major chord built on G, the fifth degree of a the C scale. In the G scale, V would be built on D

I 64 is a second inversion (5th of the chord in the bass) major chord built on the first degree. Once again, in C, that would be a C major chord with G as the lowest note.

So it's not notes being compared, it's the harmonies, the underlying chords.

sounds like there is a hole in your theory study -- I think you need a refresher course.

That's where they come from -- is that what you are asking?
