reed ranks

[accordian]

hello so i'm looking at different accordions
in terms of lm lmm lmmh etc.
and to be honest have no idea what any of it
means. I would have thought that
it's just a way to get all the notes in
eg. the low for the low notes medium for medium
notes etc. but that's apparently not the case and
don't quite understand what it is im looking at

could someone please explain this to me


thanks

Well if you have two middle (M) reeds and you have them both switched on, they will both play the note at basically the same pitch.

But not exactly the same pitch. There's usually a certain slight tuning difference between them, and that difference results in a fatter, more animated sound than just one middle reed by itself. Sort of like the difference between one person singing "oooooh" and two people singing it at the same time together.

The greater the tuning difference, the fatter and more warbley the sound. In accordion terms, we call a very slight difference "dry" and a greater difference "wet".
