Welcome to Melodeon Macro An idea by Roy Griffiths
melodeon: (muh-loh-dee-uhn)There is some disagreement over the name melodeon.
In England a diatonic button accordion (which produces different notes on push or pull of the bellows)
and has one, two or three rows of buttons on the right hand side is usually called a melodeon.
In Ireland a melodeon generally refers only to one-row instruments.
In the southern United States even these are called accordions.
