Sorry, pressed bouton too soon.

Meant to say, this'll be chromatic - you'll be able to play in any key & the basses'll give adequate chord accompaniment.

Also, an 8 bass means it'll be the size & weight of a small melodeon.

I'm a melodeon player [among other insts] & find there's very few who play these & sing - prob too much brain power needed, also you're restricted to what keys you can play in.

An anglo concertina is diatonic & is set up in much the same way as a 2 row melodeon



An english concertina is also chromatic but although smaller & lighter cost a lot more than an accordeon.

Hope this helps
