[Harp-L] Hohner Echo Harp note layout

[Winslow Yerxa]

Some diatonic button accordions have the same pairings of note arrangements among their rows (each row is like a diatonic harmonica).
The idea behind this is that when you flip the harp over (or, on an accordion, switch button rows) to change key in a medley, you have a note that's close in pitch to the note in the same hole on the harp you just left. 
On my Hohner double sided D/A, the Low D side has an F#, while the A side has an A as first blow note. 
On my C/G, again the Low C side has an E, while the G side has a G. 
On the F/Bb, the Low F side has an A, while the Bb side has a Bb.

I have a 2x32 (which means 16 paired holes per side) in C and G, and a 2x48 in A and D.

The first note on the C is and E and on the G it’s a B. Comparing this with a standard diatonic, it’s as though on the 2x32, both sides of the harp start on the two hole.

But with the longer 2x48, it’s a different story. 

The D side starts on an F# (the equivalent of the two hole on a D diatonic). The A side starts on an A.

I have a Comet harp (octave harp in C and G) that is 2x40 and there it’s a similar thing: the C side starts on an E, whereas the G side starts on a G.

Why does Hohner do this? Why not start each side of the harp (for models with more than 16 pairs of holes) on the respective tonic note? 

Winslow Yerxa, would you have an idea about this?

Thanks,
John
