Never heard of it?
Mozart called it the Spattisches Klavier, after a maker of his time.
The Italians knew it as the cembalo angelico.
Now, the Russian pianist Alexei Lyubimov has recorded a set of solo works by C P E Bach who is believed to have written specifically for a Spath piano.
It’s not the first such recording on a profile label – there was one last year on BIS – but sometimes it’s the second swallow that heralds the coming of spring.
