A sound genjutsu made by whistling through a leaf infused with chakra. Due to the fact that this is a sound-based genjutsu, it doesn't require the enemy to look at the user for the genjutsu and it can be used from a distance which is a great advantage against other genjutsu which require eye-contact. The effects of the genjutsu depend on the notes the user is playing through the leaf either putting them to sleep, paralyzing them etc. Kuhaku Mugen had such a mastery over this technique which earned him the moniker "Whistler of the Leaves". This technique can effect multiple targets.
