Subject: Mode Questions ???

Can any body explain to me the significance of Mode and the Letters l,k,m.
I've been doing a lot of reading on theory and keep seeing references to
Modes and the letter l,k,m with numbers like 1:2:3: or 2:3:5 and hve no
idea of what these are. I've been reading the papers by Antonio Carlos M.
de Queiroz (great papers !!!) and he uses these all the time in his
wrightings but I can't seem to find any thing that explains the basic
concept of these modes and how they relate to coupled rsonate circuits???
    Thanks
