Blow’s charming setting of Ah, heav’n! What is’t I hear?
, published in Amphion Anglicus
in 1700, shows an elegant control of vocal line and an effective use of adventurous harmony, all contained within a compact and clearly defined structure. The duet is an excellent example which justifies the respect which Blow’s work received during his lifetime, and the unfairness of Burney’s attacks on his abilities as a composer.
