Dear Concertina Historians,
We talk all the time about Anglos with Wheatstone or Jeffries layout to distinguish between two slight variations in the right-hand outer row.
But who actually "invented" the whole outer row? Was it Mr. Wheatstone or Mr. Jeffries - or was it someone else?
And was the outer row of a 30-button Anglo always the way it is now, apart from the Wheatstone/Jeffries variations?
The history books tell us that it was George Jones who first applied the German 20-button bisonoric Richter layout to the English-bult concertina, thus inventing the Anglo-German concertina, and that this instrument became the Anglo-Chromatic through the addition of a third row of buttons, which we sometimes call the "accidentals row" because one of its functions is to provide sharps and flats other than the Anglo-German's F# (i.e. notes that are accidental to the home keys of C and G).
But who was it who thought out this ingenious combination of accidentals and reversed naturals that add so much to the capabilities of the modern, 30-button Anglo?
Enquiring minds would like to know, and I reckon Cnet is the best place to ask!
