Indeed, I've heard it said that C is
the hardest key to play in on the piano keyboard, because there aren't any black notes in it as "markers"!

But black keys are still there, aren't they? Lamp posts are there not to run into them.
Yes, but you (hopefully)
see lamp posts before you run into them, don't you? Only beginners
look at the keyboard, proficient musicians (like the top piano accordion player who made that comment) don't.

But tell me, why do you think (if you do) that 50 button Anglo in C/g is in C/g?
I certainly don't think it can only play in those keys, if that's what you mean, but having all the notes doesn't necessarily make an instrument "fully chromatic", which is in practice limited by fingering. Anglos are transposing instruments, made in a range of keys to facilitate fingering in those and related keys, so need to be described in terms of their "home" rows.

And why large diatonic 5 row accordions are called "diatonic", when they have all the accidentals?
The only large 5-rows that I'm familiar with are Continental Chromatics, which are "just what it says on the tin", but I suppose what you mean are 5-row versions of the "Steirische Harmonika" (which you would never encounter here in Ireland)? In which case "diatonic" is the traditional way in English of saying "bi-sonoric", though I understand these instruments are usually played diatonically along the straight row (?), at least that's what I've seen.

Even small 2 row Melodeon has all the accidentals, only spread between two octaves. Does it make them chromatic?
No, they're usually in two keys a fourth apart, often with no accidentals outside those keys, though sometimes with limited accidentals replacing the lowest notes of each row - making them hard to use.

Or would you consider British Chromatic been in any key?
They have a semitone difference between the rows, but again they are also transposing instruments and only "chromatic" in name and possessing all the notes. For example the B/C accordion, that is so popular in Irish music, is not good for playing in the popular fiddle key of A, whilst the C#/D, that is also used here, is similarly not good in G. Indeed, Jimmy Shand sometimes used a C#/D as a transposing instrument, to play in the "Scottish" keys of A and E, whilst using the B/C fingerings for G and D. Also, it is common to use C/C# or D/D# instruments to play in Eb.
Anyway, didn't you say "We were talking about English"?

This offset of discussion makes little sence actually, and I'm to blame.
I'm sorry for been so anal, I usually am not.
