While the Horniman Museum may currently be closed (though the gardens are open), The Horniman is still running some online events.
Watch It Live is a series of free online events from the Music Gallery, featuring performances on recently restored historical keyboard instruments. These are:
A rare surviving example of a signed Neapolitan virginals by Onofrio Guarracino, 1668;
A beautifully-preserved square piano by Adam Beyer, London, 1777; and
A handsome English chamber organ, possibly by Joseph Beloudy, London, c.1800.
Thursday sees a performance by Masumi Yamamoto on the harpsichord, and it can be viewed on their YouTube channel from 3pm:
