- Neapolitan Sixth: In practice is it very similar to a trotonic substitution, which replaces the V in an authentic cadence by a bII. In theory it's considered to be a substitution of the IV, that then becomes a bII. It's often seen in a cadence as bII - I or bII - V - I - Picardy third: In a minor tonality, that when you replace the chord of Ist degree (that then should be minor) by a major chord, in a conclusive cadence. It's used at the end of a section or at the end of a whole music. In the XVIIIth century it was considered even more conclusive than a minor authentic cadence. - Faurean cadence: That's an alteration of the half cadence. Instead of going I - V, it goes IV - V, with the IV being a 7 dominant chord with the 5th at the bass
