I was comparing the English concertina with the accordion. There's also the 
Anglo concertina, which has different notes on draw and push and has buttons 
in arcs.

The examples of reed instruments in the definition are all woodwinds, in which 
a single or double reed has little effect on the pitch, which is chosen by 
closing holes in a tube or cone that encloses an air column. The concertina, 
accordion, melodica, and harmonica are tuned-reed instruments, in which the 
pitch is determined entirely by the reed, and there is no air column. Then 
there are reed pipes in a pipe organ. They have both a tuned reed (in some, 
the air pressure is part of the tuning) and a tuned air column.
