This is an excellent idea! Wow! Thanks. But, I must say a few things:

1. The vowel 'e' in Kyrie and 'o' in Eleison, are too English. Do remember that this is Greek - 'e' (elipsion as opposed to eta) is always and consistently to be sounded like an 'a' as in 'day' ; 'o' (omicron as opposed to omega) to be pronounced always like 'aw' as in 'dog'.
2. The singing of Latin (or Greek) Chant must NEVER be unmusical. I mean, according to modern scholarship of Boethius et al, singing is smooth and they describe song as 'liquid silver from the forge', they are describung 'legato' singing here. Therefore, in this chant lesson the cantor has failed to give the necessary 'legato' to the phrases. Do not think for a moment that because this is ancient music, that the usual requistes of line, form and artistic expression do not apply - both ancient and modern music have thier origin in the same human race. We havent changed much since Boethius in our emotional make-up...
3. The modal cadences, must be clearer - the ancients have done this for us, viz. to place the accent of 'Eleison' ('le') on the cadential note, this means that the 'son' of Eleison must not be loud or accented.

But all in all nice cantor's voice! Thanks
