Voicing of Cadences
on: August 05, 2007, 02:45:36 AM
Hello my friends, I am totally new here, in the exposition of my pianistic days!

I have been studying theory most of all, as my instrument is a sub-par digital standing in for a true instrument until I can begin my official studies. While researching theory, and watching voluminous amounts of videos and performances, I became a tad confused about cadences. In particular, the perfect cadence when played as two triads does not sound conclusive to me, nearly at all. G major to C major, for example, leave me feeling as if it were two undefined and uncoloured block chords that don't really conclude. They simply sort of sit there in mid air, yet G to C is a perfect cadence.

When played as simply the note G to the note C, it sounds very conclusive, of course. However, playing the major triads does not give me that feeling of finality. A friend of mine suggested playing a G7 to C, but that sounded still less convincing as something to end upon. I am aware that a piece must begin in C for the perfect cadence to work from G major to C major, but even then if I progress from a C triad and eventually to a G triad, then back to C, it feels like something is missing.

How do perfect cadences larger than one note (i.e. chords) become conclusive sounding? I hope it's not too ambiguous a question.

Exactly what notes are you playing, bottom to top for both chords (G to C)?

A piece does not need to begin in C for a G - C perfect cadence to work, by the way.  ;)

The chords are not inverted, no. They are first position block C and G! Also, it just seemed to make sense that a piece had to begin in C for a perfect G-C cadence to sound TRULY perfect.  ;) But yes, G B D and C E G don't seem to work for me.

No in fact you don't have to start in the key you end with to get a perfect cadence.  It all depends on the context in which the cadence is occuring and how the cadence is built.

The reason I wanted to know what notes you were playing is that now I see that you're not playing a perfect cadence afterall!  You're playing an imperfect authentic cadence that is using improper voice leading.  No wonder it doesn't sound right!   ;)

Do this (from bottom up):

RH -  D F G B then E G C  *OR*  F G B D then E G C

(The F may be omitted; or if you keep the F, the D may be omitted as it is the 5th scale degree of the dominant 7th chord, and as such it doesn't affect the quality of the chord)

LH -  G then C

This is a perfect authentic cadence with proper voice leading. 

To have proper voice leading with either a perfect or imperfect authentic cadence (or plagal or half), one must invert at least one of the chords.

The other issue is that you are creating parallel fifths, which makes an unpleasant sound and disrupts the cadence.

Or you could just voice the C in the CEG... That makes it easier.
