You will need Action Replay, an iCheat, or a lot of luck.
Seeing as getting the Azure Flute was a Nintendo Event, you will need an Action Replay or an iCheat to get the Azure Flute.
You could also wait and hope that Nintendo run the Event again. They said that getting the Azure Flute was a one-off Event, but they have said that before with other Events which ended up running again.
Either way, I'd recommend iCheat. They have billions of cheats for pretty much every game there is out there made in or before 2010.
You cannot get the Azure Flute in HeartGold. The Azure Flute is only capable of being used in Pokemon Diamond or Pearl. The Azure Flute can only be obtained by an event of some sort in Diamond and Pearl.
you cant get the azure flute on Pokemon pearl except from trade events or trading
You can't without cheating
