First open quests "O", Click the recurring tab quests and look for [Contribution] [Lvl60] O'dyllita City. Start the weekly questline and it is easy, these quests will give you the Ancient Kingdom of Orzeca Coin to complete musical instruments quests and get the Dewdrops. (You have to have the instruments Blueprint in your inventory to que the quest from the NPC's. I bought all the blueprints and keep them in inventory at all times)
