First, you have to go to the Pokemon Tower in Lavender Town. Keep going upstairs until you reach the top floor. There will be at least one Team Rocket person and an old man. Then, you have to fight either a Wild Marowak or a Team Rocket person(s). When you've beaten them, talk to the old man. He'll give you a Poke Flute. After he leaves, go downstairs until you reach the bottom floor and exit the Pokemon Tower. Lastly, go to the end of Route 11, go into your bag and use the Poke Flute.
