Talk:Gravissima

Usually the lowest stop, but not always

The article currently says, "It is also usually the lowest stop in the organ that has one."

Use of the word "usually" implies that there must be exceptions. What stop would be lower than the gravissima? 75.163.218.209 (talk) 07:23, 4 November 2013 (UTC)
