Dietrich Buxehude’s chorale cantata “Jesu, my Heart’s Treasure” is, like many of the Lübeck master’s cantatas, an opulent-sounding work which produces a grand effect with simple musical means. It is a piece which can be performed at many occasions in the liturgical domain and contains no noteworthy difficulties. Besides the score with enclosed instrumental parts, the choral score and supplementary parts can be obtained separately.
