Picardy Third cadence

The Picardy Third cadence is a major triad in a minor key with Nonharmonic tones in the cadence

When i use a Picardy Third Cadence?

Why would i use a picardy third cadence?

How do i use Non-Harmonic tones in the cadence?

Non-harmonic tones would be the 2,4,6,7 degrees of the key/scale im in?

The Picardy third typically DOES NOT have non-harmonic tones - it's simply a major triad on the tonic, in minor-key music. It's often used as a final chord in a minor-key piece.

thanks for the information

Why did composers use a Major Chord in a Minor key for the cadence?

Thats like a Borrow chord in the Cadenced but why?

It is, in a piece in minor tonality, using a major tonic chord to end the piece, instead of the usual minor chord.

The major chord is more perfect than the minor chord. So the ending is more perfect, the V-I cadence is a bit stronger.

The Picardy Third can be a secondary dominant 7th chord in a minor key

A picardy Third is like a Modulation or a borrowed note or chord?

You're overthinking it. It's really very simple.

It's a type of cadence. If the piece is in a minor key, and you cadence in the tonic major, the raised third in the cadence is called a Picardy Third.

A picture is worth a thousand words, and hearing is believing. Attached is an idiomatically correct example.

It´s called Picardy third because it was used by musicians from Picardy, a province of France.

You can notice in Bach´s French suites the minor movements finish with it.
