oh, i didnt realize you went on a weekday. during lent no masses (divine liturgies) are allowed to be said on weekdays (on sundays it is allowed because sunday is technically in the byzantine church outside of lent, but one still has to keep their personal fast of what they gave up for lent), so on weekdays instead a liturgy of pre-sanctified gifts is offered where the eucharist given at communion was pre-consecrated the previous sunday and stored in the tabernacle.
so clear up confusion, there are three liturgies:
-Divine Liturgy of St John Chrysostom: said through out the year except during Lent
-Divine Liturgy of St Basil the Great: said on Sundays during Lent
-Liturgy of Presanctified Gifts: said on weekdays during Lent, there is no canon/Eucharistic prayer, only pre-consecrated eucharist from previous sunday is used. the liturgy of presanctified gifts is similar to vespers.
if you went on friday and took communion, you went to the pre-sanctified liturgy.
all liturgies are supposed to be sung/chanted - the sunday divine liturgy will probably mostly be sung/chanted - but the length of the psalms chanted are a lot less than what you experienced on friday. i guess you’ll have to go and see for yourtself to understand
it may seem intimidating at first but after a couple months you’ll have no problem and everyone, even cradle, still learn new things
