Beat team rocket at Celadon City underground from the slot machines. The leader, Giovanni, will give you the silph scope. You can then beat the Pokemon tower in Lavender Town. When you beat it, Mr. Fugi (the guy you save at the top of the tower) will take you into his Pokemon fan club house and give you the pokeflute.
You can find the Poke Flute in the Pokemon Tower. After you free Mr. Fuji, he will give you the Poke Flute.
with the poke flute
The Poke Flute wakes up sleeping Pokemon, and was a key item in Pokemon Red, Blue, Yellow, FireRed, and LeafGreen. It could be used in or out of battle. The Blue Flute, however, as far as I can tell, only wakes up one Pokemon. I hope this helped.
Save Mr. Fujii in the ghost tower in Lavender Town.
you will need to have Poke Flute to awaken the sleeping Snorlax who is blocking the way.
