re: "Uh, there's not much to know. I have an English concertina too. It was explained to me that the two middle rows on each side are like the white keys on a piano, alternating side to side. The outside rows are all the accidentals."

But did you know that the English key arrangement has 14 notes to the Octave? In 1830's when Wheatstone invented it, scales were diferent - G sharp and A flat were different notes for instance. Now-a-days the scales have been "harmonised" in the Euro-standard meaning of the word. That's why you will find two notes per octave duplicated.

On another point - never use the bellows to produce punch to your notes, the reason that bad Anglo (and melodion) players sound bad is that they use the bellows to modulate the reeds. Good players use the buttons to modulate the notes, that way they have control. The real trick to producing punchy music is to cut notes off short - it's the end of the note that produces punch, not the begining.

There is however some excuse for using the bellows to produce gentle tremelo effects.
