How To Get The Poke Flute In Pokemon Heart Gold?

In lavender town

You get the poke gear radio upgrade in the Kanto region then go the Snorlax and slide the circle up to the top then shut the poke gear off and click on the Snorlax and he will battle

Go to Celadon Game Corner and pull the lever behind the poster, then go
through there, beat Team Rocket Boss and grab Silph Scope. After that
go to Pokemon tower and get to the top to Mr Fuji, then go with him
back to his house and talk to him, he will give you the Poke Flute.

Walk up to snorlax once you hav the radio card for kanto and open the radio slide the tuneing dot to the top of the bid radio circle and pokeflute will turn on and close the pokegear window and click A on snorlax while the flute is still playing, and he will battle. By the way, I don't even know if snorlax is a boy or a girl.

No one is correct bout this

You don't

It available in lavender [now its a radio tower] a guy upgrades your poke gear radio thing and you play it near the snorlax ;] hope this helps
