Koopman Bach Cantata 18

This twenty-second and last volume of cantata recordings contains two of Bach's latest cantatas (BWV 30 and 80), including the secular model for BWV 30 and Wilhelm Friedemann Bach's arrangement of two movements from BWV 80 dating from after 1750. Also included are the four Kyrie-Gloria masses of the late 1730s; they are very closely associated with the cantata repertoire of the 1720s. These masses are based on selected movements of cantatas dating from the period 1723-6; after an interval of ten or so years Bach reworked them, in most cases very thoroughly. Renowned Bach specialist Ton Koopman (1944) was awarded the 2006 Bach Medal by the city of Leipzig 05 Jun 2006, the final day of this year's annual Leipzig Bach Festival.

In the autumn of 1713, Bach was invited to apply for the post of organist and music director at the Marktkirche in Halle in succession to Handel's teacher, Friedrich Wilhelm Zachow. Bach was honoured to accept the invitation and in doing so made it clear that he was keen to extend his activities. Under Zachow, who had created a respectable repertory of sacred works of the most varied genres, including a large number of church cantatas, music in Halle had flourished and reached a level that offered Bach an area of responsibility that he evidently found attractive.

The cantatas of volume 19 can be relegated to three groups: Four works (BWV 72, 88, 129 and 193) belong to the third Leipzig series, lasting from 1725 to 1727; five (BWV 145, 159, 171, 174 and 188) belong to the group known as the Picander cycle of 1728-29, which was not completed or has not survived complete; two works (BWV 51 and 117) belong to the period after 1730, in which Bach composed new church cantatas only sporadically.

Bach's 200 existing cantatas (100 more have been lost) represent one of music history's most remarkable achievements. The first volume in Erato's ambitious but much-needed traversal of the complete canon contains nine cantatas from Bach's early career. Except for "Christ lag in Todesbanden," these are lesser-known works, yet that doesn't mean they are of lesser quality. Here are some of Bach's most compelling choruses, accompanied by colorful and ingenious instrumental writing. Highlights abound, including the appendices that reproduce Bach's revised versions of cantatas 4 and 21. The choral singing is excellent: sensitive and agile, with unforced tone.

The cantatas in this sixteenth volume are all from the third cycle of Bach's Leipzig cantatas. This yearly cycle began on the First Sunday after Trinity (3 June) 1725 and extended over a period of about three years - unlike the two preceding cycles of 1723-24 and 1724-25. Bach's rhythm of composition had slowed down markedly in the middle of 1725. It is also significant that from February to September 1726 he performed a long series of cantatas by his cousin Johann Ludwig Bach (1677-1731), Kapellmeister at the ducal court of Meiningen. But even if the proportion of original compositions declined markedly, these include a series of particularly accomplished and extended works, such as Cantatas BWV 43, 39, 170 and 102. Musically, Bach's third yearly cycle of cantatas is distinguishable by the fact that they do not begin with large-scale instrumental symphonies, nor do they have unusually extended or richly scored opening movements.

The 18th set of Bach's cantatas contains exclusively works of the third yearly cycle from Leipzig. Unlike the first two Leipzig yearly cycles, this one extends over a longer period: from June 1725 until 1727. The works in this set belong essentially to the years 1725-26 and are in some cases chronologically contiguous (BWV 187 and 45; BWV 98, 55, 52), with the result that the original sequence can be easily grasped.

The fourth volume of our complete recording of Bach's cantatas completes the series of secular cantatas from the composer's years in Leipzig. Seven works are involved here, spanning a period from 1725 to1742, the year of Bach's final secular cantata, BWV 212. Of Bach's occasional compositions, some fifty secular pieces have survived, yet these represent no more than a fraction of what must once have existed. Bach's secular cantatas cover a period of almost exactly three decades.

Volume 17 in the Bach cantata series contains exclusively works from the third yearly cycle of cantatas from Leipzig, which, unlike the previous two Leipzig cycles, extends over a longer period of time, from June 1725 until 1727. The cantatas in this volume can be divided into three chronologically distinct groups: December-January 1725-26 (BWV 57, 32), September-October 1726 (BWV 35, 17, 19, 169 and 56) and January-February 1727 (BWV 58 and 84).

The cantatas in this fifteenth volume belong mostly to the transitional period between the second and the third yearly cycle of cantatas, i.e. the spring of 1725. BWV 3 is part of the series of chorale cantatas that give the second yearly cycle its special character, whereas BWV 28, 110, 146 and 168 already belong to the third yearly cycle. However, cantatas BWV 85, 87, 108, 128, 175, 176 and 183, mostly compositions on texts by Mariane von Ziegler, bring the second yearly cycle to its conclusion. Bach had taken up his position as Kantor of St Thomas's, Leipzig, at the end of May 1723 and so begun his regular performances of cantatas on the First Sunday after Trinity - in other words, in the middle of the church year.

The fifth volume of our complete recording of Bach’s cantatas completes the series of secular cantatas from the composer’s years in Leipzig. Seven works are involved here, spanning a period from 1725 to 1742, the year of Bach’s final secular cantata, BWV 212. Of Bach’s occasional compositions, some fifty secular pieces have survived, yet these represent no more than a fraction of what must once have existed. Indeed, there is no other group of works by the composer that has suffered such great – and regrettable – losses. In the case of more than half of the works that are known to have existed, only the words, but not the music, survived. Quite how many pieces may have disappeared without leaving any trace whatsoever is impossible to say.
