Today's Obscure Word: Flageolet

I was able to get Samuel Pepys' diary on my Kindle app and I am reading it.  He was a minor public official during the end of the Protectorate and the Restoration.  He provides a lively account of life in that time.

Today he mentions playing his Flageolet, a type of wind instrument.

Will I remember this word in a year?  Maybe.  I picked up some words from T E. Lawrence's Seven Pillars of Wisdom so maybe.  "The horse staled all over the hired help," so I got him a carrot.
