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 (=


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

Answer 1

What you are listening for is the relationship between two chords. That's what ear training is all about. I don;t know if I can tell you what to listen for in a printed message. Perhaps if you went to a keyboard and played these two-chord groups you would get a better idea:

In C, a IV - V would be an F chord followed by a G chord -- the voice leading is a problem there because their roots are a step apart and therefore have no common tone. I suggest you do it this way -- left hand plays F, while the the right hand plays C, F, and A (botton to top) -- thats the IV. Then the left hand plays G, while the right hand plays B, D, and G -- That's the V. If you want a common tone, you can add an F just below the G, making it a G7.

The I to V is easier -- just play the right hand CEG followed by BDG.

The I 6/4 is pretty easy too: Play right hand GCE followed by GBD, while the left hand plays a G both times.

Make sure that you keep in your ear the tonal center of the key you are working in. So before you do each of these, play a V I progression so that you have a full cadence in your ear -- then the half cadence thing will make sense to you.

Send me $50 dollars for the theory lesson.

Answer 2

Glinzek's examples are correct. In the IV - V progression (or any progression by step) a common tone is not necessary as long as the upper three voices move in the direction opposite the movement of the bass line.

Gee Glinzek, you are expensive. I would have done it for $35!

If you need practice in identifying cadences then get off the computer and do some work.
