I'm wondering what to make of the bass notation in this snippet of En Dro from diatonia.net. (To see the entire sheet:
http://www.diatonia.net/home.html > Bretoni button on the left > En dro - Tradizionale PDF.)
I guessing that in measure 1, I should hold the A and a for the entire beat and shorten the G and C, perhaps playing them as staccato? If so, what does measure 4 mean, what with the lack of a vertical line above the E and no vertical above or below the e?
Also, Yann Dour's Volume 2, p 5, names a similar tablature: International system "push / pull". This makes me wonder if there is also a name for the notation used on diatonia.net and perhaps a guide to it's details?
