I admit to having the complementary problem: I can sing well, but Herself was intimidated by an alleged teacher at a formative age, and spent decades thinking she was tone deaf. I quickly amended that to "tone dumb"*, as she could hear and appreciate tunes, but couldn't reproduce them unless she was singing lullabies to the children.

Much careful and non-judgemental work later, she can sing in front of grownups, modulo the occasional panic attack. Keep at it, BlackAcornUK, and practice at full pelt.

* A term I first heard from Pete Atkin, describing Clive James. He may or may not have been joking when he added: He can't even tap his foot to a Tamla Motown record.
