Paragon Skill Name Breakdown

Meh, the fruits of my anti-social life.

Here is a list of what all those skill names mean when it comes to paragon chants and echos.

Chants:

Song - trigged by using any skill
Aria - trigged by using a spell
Anthem - trigged by using an attack skill
Lyric - triggered by using a signet
Chorus - triggered by using a shout or chant
Ballad - triggered when you take damage

Echos:

Refrain - reapplies at the end of a chant or shout
Finale - trigged at the end of a chant or shout; does not reapply

there you have it, makes things a little easier when glancing at skills.
