"The only known keyboard work of this ‘organiste ordinaire’, a 12-bar Fantasie sus orgue ou espinette (possibly a fragment), would scarcely deserve notice were it not for the fact that almost no French keyboard music survives from Costeley’s lifetime – and most of that is arranged from vocal originals. Yet tentative reconstructions of the fantasy, which is preserved in an incredibly garbled manuscript apparently written by a non-musician, reveal none of the idiosyncrasies of Costeley’s style and shed little light on the missing repertory of the many French keyboard players of the period."
