I can read tabs pretty well and i have been playing the guitar for more than a year now, but recently when i searched for tabs for classical numbers i found these tabs where the numbers are written bellow the low e string line. What does that mean ? .... okay for example check this tab for Schoner Gotterfunken by Beethoven here http://www.azchords.com/l/ludwigvanbeethoven-tabs-2389/schonergotterfunken-tabs-227349.html
See the 3 1 4 in the first measure , below the low e line
