The article discusses the contribution of Hungarian musicologist Lázló Dobszay in addressing the issue behind the inseparability of music and liturgy in the Catholic Church. It states that Dobszay, with the assistance of Father Robert Skeris, pointed out the Roman Rite must be a sung liturgy and that the Propers of the Mass are the reference text for what is to be sung by the choir. The author believes that Dobszay serves as an inspiration in merging liturgy and music.
