Marsyas, the Aeonic instrument, grants you the ability to use the special song “Honor March.” This effect of this song is quite close to combination of Sword Madrigal, Archer’s Prelude, Valor Minuet III, and Advancing March all rolled into one.

SE is there a reason why Prelude is the higher tiered song, while the others are the lower tiered one?

Sword madrigal, Advancing march, Valor Minuet III are all the lower tiered versions of songs, I would have thought it would be Hunter's prelude that would be included, not Archer's Prelude.
