Throughout his life, Bach showed exceptional talent as a pedagogue. As an orphan who had been obliged to learn everything by himself, he retained the deep-rooted urge to teach and pass on his knowledge. His cantatas are spiritual lessons, just as his keyboard works constitute a tutor in the instrument. It was with his children, first and foremost, that he exercised this talent as a born teacher, and particularly with his prodigiously gifted eldest son, Wilhelm Friedemann. For him he wrote the Two-part Inventions and Three-part Sinfonias; for him too The Well-Tempered Clavier and the Orgel-Buchlein (Little organ book); and this extraordinary method culminated in the Trio Sonatas for organ. The cantata Geist und Seele wird verwirret (Spirit and soul are dumbfounded) BWV 35 is one of the three written for solo alto without choral participation and with reduced instrumental forces. The work comprises two parts, for performance before and after the sermon. Soloist and organ engage in a dialogue charged with the elation of trust in God, brimming with coloratura passages and runs. Also for alto solo, the cantata Vergnugte Ruh, beliebte Seelenlust (Contented repose, beloved heart’s desire) BWV 170 dates from just six weeks before Geist und Seele. It too features a solo organ part, later transcribed by Bach for flute and continuo. The cantata is based on a passage from the Sermon on the Mount in which Christ urges his listeners to live in peace with others.

Accompanied by his ensemble Le Banquet Céleste, the countertenor Damien Guillon places his voice at the service of a programme of vocal pieces by the German Baroque composer Philipp Heinrich Erlebach, a large part of whose output was destroyed in a fire at Rudolstadt Castle in 1735. Among the works that have come down to us are the two collections Harmonische Freude musikalischer Freunde, containing respectively fifty and twenty-five arias for one to four solo voices, instrumental ensemble and basso continuo. Most of the German texts of these pieces depict humankind at the mercy of an unpredictable and volatile destiny. Alongside natural phenomena such as storms, dark clouds and withered leaves, the poet also chooses the expression ‘bloody comets’ as a metaphor for torment and ‘the distress of the heart’. In fact, the biggest comet of the seventeenth century appeared in Europe in 1680: contemporaries feared these celestial bodies, seeing them as bad omens.

The powerful Catholic Archbishop of Salzburg, renowned for the extraordinary religious ceremonies held at his cathedral, received a splendid festival mass from Muffat. Muffat was a true European: he studied music in Paris with Lully, was an organist in Alsace, and had positions in Vienna, Prague, and Salzburg. He was a man who fused Italian, French and German styles, adding his extravagant verve, especially for this 1690 Pentecost. The music is written for twenty-four different voices and has to be distributed through the space by five choirs, along with impressive effects from the trumpets and percussion. The Royal Chapel allows this “immense” music to be set in space as it deserves. Le Banquet Céleste (Damien Guillon) and La Guilde des Mercenaires (Adrien Mabire) rise to the challenge of performing this work of exceptional proportions!

Ever since the foundation of his ensemble in 2009, Damien Guillon has been forging ahead in the (re)discovery of J. S. Bach’s cantatas. ‘Trinitatis’ is devoted to three cantatas for the season after Trinity, for which Le Banquet Celeste has assembled its most seasoned members. Three very different works in which Bach expresses in various ways the emotion that the subject of the prescribed Gospel for the day stirred in him.
