In Greek traditional music, rhythms are usually named after the dance they provide accompaniment to. In Greece, there is a dance named 'Kalamatianos' (meaning from the region of Kalamata), and this version of the rhythm is named after this dance. However, one can find a quasi-similar rhythm (still 7 beats=3+2+2, but with different inner-grooving details) accompanying other dances (with totally different steps and movement), such as Raiko dance (from the overall Macedonian region), Sirtos or Macedonian Sirtos (danced all-over north Greece), numerous Bulgarian (such as Pravo and Lesno) and other dances from the Balkans. Hope that this explanation helps and does not confuse you further...

Hi Fred! I use piano's finger numbering: 1 (thumb), 2 (index / grooming), 3 (middle), 4 (ring), 5 (little). Te and Ti are played Delhi-style closed Te. 4&5 means ring and little finger joint together (touching each other) and striking their regular spot, which is next (outwards) to the shyahi. Hope this helps...
