78 - 45 - 33 - 16

I played an album on my turntable the other day at a different speed just for fun but of course it only had two speeds. There were four RPM settings on the record player in our home as kids which was an endless source of amusement for us playing records at various speeds. Playing an LP at 78 was great fun. We had some 78s around the house but I never knew anyone who owned a 16 rpm record which was extremely slow and sure made our 45s sound weird.

The 16s were created in the mid 50s for some kid records and for blind people because of the very slow speed the record could play for a long time without needing to change it but it wasn't a very successful product.
