Johann Sebastiani (30 September 1622 – 1683) was a German baroque composer.
His works include sacred and occasional pieces and songs; the most famous is his St Matthew Passion (before 1663, performed again 1672).
[1] This work is a development from the style of Heinrich Schütz which includes recitatives and arias but avoids a dramatic operatic idiom, and marks an intermediate position between Schütz and Bach such as those of Johann Theile and Johann Valentin Meder.
In 1672 Sebastiani got married and from that point until the end of his life he was concerned primarily with the publication of his works.
In 1672, he published a collection entitled Erster Theil Der Parnaß-Blumen, Oder Geist- und Weltliche Lieder.
