LMMM - LMMH

[efibau]

I need a simple explanation between accordions with LMMM vs LMMH.

 

[JIM D.]

Your question is on the reed sets of two 4 reed accordions. The LMMM model will have one set of (L) low reeds and 3 sets of (M) middle reeds. The LMMH model will have one set of (L) low reeds 2 sets of (M) middle reeds and one set of (H) high reeds. Now there can
be a more detailed answer but you've asked for a simple explanation.

Thank you Jim. I meant more about which kind of sounds will be at each reed? I mean for example: Bassoun, clarinet, picolo- to what reed they belong- L M H ?

Hiya,

L is 'low' or 16' in organ terms, plays 1 octave lower
M is 'middle' or 8' in organ terms, plays normally
H is 'high' or 4' in organ terms, plays 1 octave higher.

Now have a look at https://en.wikipedia.org/wiki/Accordion_reed_ranks_and_switches
