Cadence

In music, cadence is something which creates a sense of resolution. It is just like completion of something. Just like the completion of a phrase, musical line, riff etc etc. Just like we write English, we use commas and full stops to show or indicate the completion of a sentence or a part of sentence. The comma represent a partial completion while a full stop represents the ultimate completion of the sentence.

Similarly, cadences represent the kind of resolution a musical line is going to have. The knowledge of cadences is important when it comes to creating harmonies and chord progressions. With the study of cadences one can realize that which chord after the other gives what kind of mood to the harmony. Try to play these chord sequences and feel the mood. Lets dive into the cadences.

The basic cadences are:
1. Perfect/Authentic cadence
2. Half cadence
3. Plagal cadence
4. Deceptive/Interrupted cadence
5. Inverted cadence


PERFECT CADENCE
The chords are played in their root position and the progression ends with V-I. So, to create a perfect cadence, the chord progression should end on the I chord from the V chord.
This is the strongest cadence and creates a great sense of resolution. It creates a very strong musical statement and creates a complete harmonic and melodic closure. Just like a full stop!

There is one more in this category which is the imperfect authentic cadence. It is divided into three parts.

IMPERFECT AUTHENTIC CADENCE (IAC) TYPES

1. ROOT POSITION IAC
This one can be treated similar to the perfect cadence but the chord voicing that is being used should not be having the root of the chord as its highest pitch.

2. INVERTED IAC
When one or both of the chords are inverted, the perfect cadence changes into inverted imperfect authentic cadence.

3. LEADING TONE IAC
The V chord is replaced with the viio/subV chord but the progression ends on the I chord.

HALF CADENCE
This cadence is observed when the progression ends on a V chord and sounds incomplete. So, this is a weak cadence and in gives a feeling that the progression should continue to some other chord.

PLAGAL CADENCE
When the progression ends on IV-I, plagal cadence is observed. It is a little weaker than the V-I cadence.

DECEPTIVE/INTERRUPTED CADENCE
The progression ends with V-vi in this cadence. This is also a weak cadence and gives a feeling of hanging somewhere in the middle.

INVERTED CADENCE
When the progression ends where the last chord is inverted, it is called inverted cadence. It may apply to any of the above cadences.

So, you must be wondering what should I do after knowing about the cadences. The use is in forming your own chord progressions. If you know, any diatonic chord can move to any other diatonic chord. So, in the major scale we have seven chords. And any chord can come after any chord. But while creating a chord progression, you must be searching for chord sequences which gives excitement or relaxation or smoothness or flow or whatever you can think of.
Try playing the cadences on your instrument and try to inculcate the feeling of those cadences. So, in this way you can grasp the feel about how the progression may sound if a particular cadence is applied. So, after this whenever you are going to create a chord progression, you already will be knowing which chord to play to give a concerned kind of feel to the chord progression.
