Music of Old Serbia is an album by soloist Dragoslav Pavle Aksentijević with Ensemble Renaissance, released in 1987 on the PGP RTs label (re-released in 1997).
Most of the material from this album is a remaster from Music of the Old Serbia, only this edition is dedicated exclusively to the Medieval Serbian chant and important members of the Serbo-Byzantine school.
The lead singer (protopsaltos) would sing the initial intonational formula which was actually an abbreviated melodic preparation for the song, a melodic-rhythmic unit which characterised a certain church melody (knowledge of these formulae made it possible for an experienced singer to sing the whole song).
If the melody were melismatic, the soloist would sing alone, accompanied by a sustained tone by the choir, the ison.
Even though Kir Stefan, Isaija and Nikola are the only reliably Serbian Medieval composers known till now, there is another name: "Joachim domestikos of Serbia" — as he signed in 1453 in more places in the manuscript number 2406 from the Athens National library.
