What are you talking about? Typica without a priest has no litanies and everything is said, there is no "choir" without a priest present.
We must come from differing traditions with regard to these things.
In the Russian Church Abroad the choir sings most of Typika (when no priest is present) - the Beatitudes, Trisagion, Creed, Our Father, troparia, etc.
The below is what substitutes for a kind of expanded Litany of Fervant Supplication...
Reader: Remember, O Lord Jesus Christ our God, Thy mercies and bounties which are from all eternity, and through which Thou didst become man and didst will to suffer crucifixion and death for the salvation of those who rightly believe in Thee, and having risen from the dead didst ascend into heaven, and sittest at the right hand of God the Father and regardest the humble entreaties of those who call upon Thee with all their heart: Incline thine ear, and hear the humble prayers of Thy worthless servants, as the fragrance of spiritual incense, which we offer to Thee for all people. And first remember Thy Holy Catholic and Apostolic Church, which Thou hast provided through Thy precious blood. Confirm, strengthen, extend, and increase her, and keep her in peace, and for ever proof against the power of hell. Calm the dissensions of the Churches, and foil the plans of the powers of darkness, dispel the prejudice of the nations and quickly ruin and root out the risings of heresy, and frustrate them by the power of the Holy Spirit.
Choir: Lord, have mercy (after every petition).
Reader: Save, O Lord, and have mercy on our president and all in authority throughout the world, commanders-in-chief of armies and navies and air-fleets, governors of provinces and cities, and all the Christ-loving navies, armies, and police; protect their power with peace, and subdue under their feet every enemy and foe, and speak peace and blessing in their hearts for Thy holy church, and for all Thy people, and grant that in their calm we too may lead a quiet and peaceful life in true belief, in all piety and honesty.
Choir: Lord, have mercy (after every petition).
Save, O Lord, and have mercy on Orthodox Bishops, the Priests and Deacons, and all who serve in the Church and whom Thou hast ordained to feed Thy spiritual flock; and by their prayers, have mercy on us sinners.
Save, O Lord, and have mercy on our parish priest(s); with all his (their) brethren in Christ, and by their prayers have mercy on us, wretches that we are.
Save, O Lord, and have mercy on our spiritual fathers and by their prayers forgive us our sins.
Save, O Lord, and have mercy on all workers in our parish, our brethren and sisters, and all Christians.
Save, O Lord, and have mercy on our parents, our brothers and sisters, and all of our relatives, and the neighbors of our families, and our friends. And grant the Thy worldly and spiritual goods.
Save, O Lord, and have mercy according to the multitude of Thy bounties, on all priests, monks, and nuns, and on all living in virginity, devotion, and fasting, in monasteries, in deserts, in caves, on mountains, on pillars, in hermitages, in the clefts of rocks, and right faith in every place of Thy dominion, and devoutly serving Thee, and praying to Thee. Lighten their burden, console them in their afflictions, and grant them strength, power, and perseverance in their struggle, and by their prayers grant us remission of our sins.
Save, O Lord, and have mercy on the old, and the young, the poor and destitute, the orphans and widows, the leper colonies, epileptics and spastics, and all those in sickness and sorrow, misfortune and tribulation, captives and exiles in mines, prisons, reformatories, psychiatric hospitals, and especially on those of Thy servants suffering persecution for Thy sake and for the Orthodox Faith from godless peoples, apostates, and heretics. Visit, strengthen, comfort, and heal them, and by Thy power quickly grant them relief, freedom, and deliverance.
Save, O Lord, and have mercy on our benefactors, who have mercy on us and feed us, and us of anxiety by giving us those things in which we stand of need, and entrust us, unworthy as we are, to pray for them; and give them Thy grace, and grant them all their requests which lead to salvation, and the attainment of eternal joy.
Save, O Lord, and have mercy on all in our parish, and on all Orthodox Christians who are messengers and missionaries in Thy service, and are travelling.
Save, O Lord, and have mercy on those whom each of us hast offended or scandalized by our madness or inadvertence, and whom we have turned from the way of salvation, and whom we have led into evil and harmful deeds. By Thy divine providence restore them again to the way of salvation.
Save, O Lord, and have mercy on those who hate and offend us, and do us harm, and let them not perish through us sinners.
Illumine with the light of grace all apostates from the Orthodox Faith, and those blinded by pernicious heresies, and draw them to Thyself, and unite them to Thy Holy, Apostolic, Catholic Church.
Remember, O Lord, those who have departed from this life, Orthodox kings and queens, princes and princesses, Orthodox Patriarchs, Metropolitans, Archbishops, and Bishops, Priests and Deacons, and those who have served Thee in the Monastic State, and the departed founders of this church and grant them rest with the Saints in Thy eternal dwellings.
Remember, O Lord, the souls of Thy servants who have departed in sleep, our parents and all of our relatives according to the flesh; forgive them every transgression, voluntary and involuntary; grant them the kingdom and a part in Thy eternal joys, and the delight of Thy blessed and everlasting life. Amen.http://www.fatheralexander.org/booklets/english/hours_typica.htm
