Mesu puntu (m)
(with) definite article: ? [su?]Meaning "(the) middle [central?] point [key]" (which refers to a key close to G), its obsolete name was discovered (in the late 1950-1960s) by Dionigi Burranca; Bakx mentions it as one of 8 obsolete or rarely used types (the other 7 being the Fiorassiu argentinu, Fiuda allirga, Fiuda bagadia in fa minore, Mediana in re maggiore, Morisku, Punt’’e Kirias, and Tertsu puntu), stating that some (though failing to specify which) of these are, as he calls them, "fake" kuntsertus.
