Can you be a bit more specific? Are you able to bring up the tabs (tablature) on the tef reader? If you can, then the tabs represent the 6 strings on the guitar and the numbers represent which fret to put you finger on. The tabs in the tef files show primarily the leads to the songs. The strumming patterns for playing rhythm are not really shown, other than to show which chords to play. When playing chords, you should alternate a bass note from the chord (on string 4,5, or 6) with strumming the 3,2,and 1 strings, as in bass-strum-bass-strum-bass-strum etc. Hope this helps. Maybe you can provide more details about what you're having trouble with.
