Five are by Orlando Gibbons, and three by Randall Jewett, a member of the choir at Chester Cathedral and brother of the better-known Randolph Jewett, possibly a pupil of Orlando Gibbons.
The entire "Battle" sequence by William Byrd is included as one piece (also found in My Ladye Nevells Booke).
Pieces 1-28, corresponding to the hand of the first Priscilla Bunbury, contain full fingering indications.
As far as the right hand is concerned, these follow the modern system, with the thumb numbered "1" and the little finger "5".
The system is however reversed for the left hand, where the little finger is numbered "1" and the thumb "5".
