I think its precise orgin in lost in the mists of time. 
The use of 'single' as a noun to refer to a single change 
introduced into a method, probably by a conductor saying 
'single', in a place where there would otherwise be a double 
change was already established by 1668 when Tintinnalogia 
was published.  It could well have originated in Grandsire 
Doubles; certainly it seems likely its origin was in doubles 
rather than minor.
