G. K. Michalakis:

An excellent example of "Eleutheros chronos". This by no means implies that ALL
koinonikon was chanted as "eltutheros chronos", and we have an excellent example
af a regular haplos chronos of an abbreviated version of the above by the Protocanonarchos,
Stylianos TSOLAKIDIS. The different ways of counting chronos -haplos,
diplos, syneptigmenos, eleutheros - is not uniquely linked to each hymn type,
and one could choose according to the situation... haplos or eleutheros for koinonikon,
with syneptigmenos for the tenena, for instance, or haplos, with passages of eleutheros
(e.g. as done by Protocanonarchos Tsolakidis).
