Killian Keys was founded in 2006 by Sean L. Killian, a long time pianist and avid sheet music
collector. The Killian Keys brand remained in local Northern Illinois until 2009 when the store hit
the web in an effort to reach demand and a national market. With over 3000 titles available,
Killian Keys is one of the largest online sheet music companies around. Whether you are
looking for a 19th century tap hit to a Big Band Era platinum record, Killian Keys has all the
antique sheet music titles & piano accessories you need!
