I like your arrangement very much, likewise the performance--pensive, evocative of the lady of its dedication, who led a rather agitated life which must have put her "in the dumps" more than once. This famous piece may be the work of Hugh Aston (c.1485-1558), one of the earliest English keyboard composers whose name is known to us. Only a few of his keyboard pieces survive, found in the same MS as 'My Lady Carey's Dompe'. The piece reveals a composer of imagination, which Aston certainly was. He seems to have been in and around London in the 1520s, when Mary Carey (née Boleyn) was having her own fling with King Henry VIII, later to be eclipsed by her famous sister.
