Vivaldi is a composer from a period when the sixth semi tone,

or the fifth flat, or the devil note, were not allowed at all by the church.

He had to follow very strict rules,

that's why his music sounds very childish (in my paradigm).

While Debussy is a more modern composer,

he has been very influenced by Erik Satie which has stopped to follow the old rules of harmony imposed since centuries, they have introduced the concept of enharmony, and arythmic patterns.

>What is a tri-tonic substitution?

 

The seventh flat in a major chord is the triton of the major third, if we substitute a 7 flat major chords with another one, _six semi-tones below_, or above (same one), we will get the same notes than the altered chord.

The altered chord is often used instead of the 7 flat major chord for resolving

to the major chord or a minor chord one fift above.

 

It's a kind of mirror effect.
