When I sang in a choir, many years ago admittedly, we spoke of stave and staves rather than staff and staffs. Don't know if this is common in the UK.

My efforts were more energetic than tuneful as, although I enjoy listening to music, when it comes to producing musical sounds, by whatever means, I am basically tone deaf! The grammar school that I attended had the conductor of the National Youth Orchestra as music teacher and the whole school took over a local church twice a year to deliver Handel's Passion and Messiah.
