The main focus is expected to be on plucked keyboard instruments, harpsichord, spinet, virginal, muselaar, etc; but clavichord and other early keyboards are by no means excluded. Discussion of historical organs, early pianos and their repertoire is not precluded; but there are other forums for 19th century and later organs and modern pianos and discussion about them here is not appropriate.
Announcements about instruments for sale or concert promotions by individuals are acceptable within reason.
