for the avoidance of doubt, since these things can be typographically tricky: my clue 7 is a capital letter I rather than a lowercase L or a digit 1 or a vertical bar.
@MikeQ I'd been guessing either CLAVIER or CLAVICHORD for 4, more likely the latter, and either CLAVIER or CLAVICHORD for 5, more likely the former. Oh well.
