Reed Pipes

Reed Pipes are a type of musical instrument used by satyrs. When satyrs play certain songs, the ones that are magic, they can help them in many ways such as growing plants, capturing enemies, and keeping away insects and other pests.

The Lightning Thief
Grover is Percy's best friend and he went on Percy's Quest for the lighting bolt. During this Grover tried to work his reed pipe to help them but it just sounded bad.

The Titan's Curse
Grover uses his reed pipes to impress Zoë and Bianca, but instead created poison ivy. Grover also uses it to play a Barry Manilow song as a confusion spell to confuse the security guards in the Smithsonian museum.

The Last Olympian
Grover uses it to open a pathway known as Orpheus' doorway to the Underworld for Percy and Nico and used it to imprison Hyperion. During the Battle of Manhattan, the satyrs used their reed pipes to combat Hyperion and his army. Grover also used it against Kronos on Olympus to create plants to interwine his legs, but Grover stopped playing too soon and the magic was too weak to be much use, and was broken.
