Go to Lavender Town and through the Pokemon Tower to the top floor and the man on the top has a Pokeflute.
You will get the PokéFlute as a reward from the caretaker of the Pokémon Tower, Mr. Fuji. You need to finish the Pokémon Tower in Lavender Town first.
After you've received the Silph Scope from Team Rocket in Celadon City, you'll go to the top floor where a ghost will be. When you use the Silph Scope on this ghost, it will turn into Marowak, which you'll have to defeat.
After that, you can go to the next floor and battle the Team Rocket members, then on the top of the tower you'll find Mr. Fuji. He will take you to his house and when you talk to him, he'll give you the PokéFlute.
You need to use the pokeflute on snorlax to wake it up.
Snorlax is in two locations to the west of celadon city and to the east of vermillion city just use the pokeflute to wake it up. Didn't catch it? Get the purified snorlax from Pokemon xd gale of darkness.
Use the pokeflute.
In Pokémon Pokémon FireRed and LeafGreen you will encounter a sleeping Snorlax blocking the way. To wake him up you need to get the Pokeflute.
You do not receive the pokeflute in Pokemon heartgold. After you get the machine part in misty's gym and returned it to the powerplant you can get the kanto expansion card for your pokegear radio at laventer town radio tower. The pokeflute station is near the top
