[2] By November 1615 Hooper had attained the prestigious position of joint Organist of the Chapel Royal with Orlando Gibbons.
Apart from seven keyboard pieces that have survived (two of them included in the Fitzwilliam Virginal Book)[4] Hooper's compositions are all sacred anthems and liturgical settings.
Two pieces were included in Sir William Leighton's Teares or Lamentacions of a Sorrowful Soule (1614), and three anthems were printed after his death in John Barnard's First Book of Selected Church Musick (1641).
[2] As William Hunt points out, "major and minor harmonies are hurled into dissonant collision in cadences that border occasionally on musical hysteria, to express both the horror and the relief of carnage narrowly avoided.
"[5] Peter Le Huray pointed out that one reason Hooper's music fell out of general use was that "nearly all of it is set to very inadequate Elizabethan and Jacobean verse", but that Orlando Gibbons, his younger colleague at the Chapel Royal, "must surely have learned much from him, for the two composers have much in common".
