Answer: ars Nova
Step-by-step explanation:
The "ars" in "ars nova" can be read as "technique", or "style". The term was first used in two musical treatises, titled Ars novae musicae (New Technique of Music) (c. 1320) by Johannes de Muris, and a collection of writings (c. 1322) attributed to Philippe de Vitry often simply called "Ars nova" today.
