The abundant legacy of Gustav Leonhardt’s recordings for Telefunken’s Das Alte Werk series invites us to follow his trajectory as a performer from the early 1960’s onwards, a time when the new codes of early music had yet to be invented, when their success depended above all on the strength of conviction of the performer. Leonhardt’s was strengthened by dialogue: with a range of partners whose variety defies all preconceived ideas, with ancient instruments or modern copies of all types, with repertoires as diverse as Byrd, Purcell, Rameau, Johann Sebastian but also Carl Philipp Emanuel Bach. Not forgetting the 1970 Monteverdi LP, which has never been reissued since. The image of a pope of early music isolated in his tower and frozen in a school style does not last long after listening to this historical sum, extended here by the later series of recordings under the Virgin Veritas flag.

Johann Kuhnau (1660-1722), Bach's eternal 'predecessor' as Leipzig's Thomaskantor, has only been rediscovered in recent years and his true greatness has not yet been truly recognised. He was highly respected by his contemporaries, however, and not just as a musician: he had a doctorate, worked as a lawyer, wrote satirical novels - a polymath… His musical oeuvre must have been extensive, much of it is lost. It is therefore all the more pleasing that his magnificent Christmas cantata "Frohlocket, ihr Volker, und jauchzet, ihr Heiden" ['Rejoice, ye nations, and shout for joy, ye heathen'] has been preserved. It opens the programme on this CD and, with its instrumentation and duration of over 25 minutes, surpasses many a great cantata by his famous successor.

The eighteenth century is probably the most extraordinary period of transformation Europe has known since antiquity. Political upheavals kept pace with the innumerable inventions and discoveries of the age; every sector of the arts and of intellectual and material life was turned upside down. Between the end of the reign of Louis XIV and the revolution of 1789, music in its turn underwent a radical mutation that struck at the very heart of a well-established musical language. In this domain too, we are all children of the Age of Enlightenment: our conception of music and the way we ‘consume’ it still follows in many respects the agenda set by the eighteenth century. And it is not entirely by chance that harmonia mundi has chosen to offer you in 2011 a survey of this musical revolution which, without claiming to be exhaustive, will enable you to grasp the principal outlines of musical creation between the twilight of the Baroque and the dawn of Romanticism.

Kuhnau’s six Biblical Sonatas are among the most fascinating keyboard curiosities of the baroque. Johann Kuhnau (1660-1722), Bach’s immediate predecessor as Thomaskantor in Leipzig, was a versatile composer, performer and polymath who produced fine works in a wide range of formats. These Biblical Sonatas were written as domestic programme music to illustrate - indeed, to describe - the following Old Testament stories: the Battle between David and Goliath; Saul Cured by David through Music; Jacob’s Marriage; Hezekiah’s Restoration to Health; Gideon, Deliverer of Israel; and Jacob’s Death and Burial.

Widely regarded as one of the foremost interpreters of Bach's music today, Masaaki Suzuki has made his name both as the artistic director of the Bach Collegium Japan and as a performer on the harpsichord and the organ. Much interest has been focussed on the BCJ/Suzuki series of Bach Cantatas, begun in 1995 and reaching its final stretch with the recent release of Volume 46 (of a projected 55 discs). Hailed by the international music press, this monumental undertaking has acquired a world-wide following. From the very beginning of the collaboration with BIS, however, there have been numerous recording projects beyond the sacred cantatas of Johannes Sebastian, and, indeed, beyond Bach himself. Some of these acclaimed recordings can now be found in a limited edition boxed set, released in connection with the 20th anniversary of Bach Collegium Japan this year.

Bach's setting of the Magnificat is one of his most often-recorded vocal works; as a rule, it's paired with one of Bach's lavishly scored festal cantatas. (The Easter Oratorio seems to be a current favorite.) Masaaki Suzuki and the Bach Collegium Japan had a different idea: they've paired Bach's Magnificat with roughly contemporary settings by Johann Kuhnau, who was Bach's immediate predecessor in Leipzig, and Jan Dismas Zelenka, who was a composer at the court of Saxony in Dresden. Zelenka is an interesting composer, among the most underrated of the Baroque era. His writing is less dense and intricate than Bach's–at times it looks forward to the simpler, more elegant style of Haydn and C.P.E. Bach. Zelenka knew his counterpoint, however, and was fond of slipping the occasional surprising chord change into his music.

Johann Kuhnau was one of life’s polymaths—as well as being a composer he trained as a lawyer, spoke several languages, helped found Leipzig’s opera house, theorized about music and even found time to write a novel sending up the shortcomings of the contemporary music scene. Musically he’s the link between Schütz and Bach, but he was alive to many different stylistic traits as this selection of sacred music demonstrates. From the brilliantly brassy opening of Ihr Himmel jubilirt to the restrained intensity of Tristis est anima mea, it’s music invigorated at every turn by The King’s Consort.

'Herzens-Lieder' [Songs of the Heart] – this title would certainly have appealed to the two librettists and four composers featured upon this CD. In terms of music and church history, they all – Johann Kuhnau, Georg Philipp Telemann, Christoph Graupner and Johann Sebastian Bach – form part of the Lutheran church choir tradition.
