This is the thirteenth and latest issue in an accomplished, 
                  acclaimed and very welcome series on Challenge. The series presents 
                  all the works of Dieterich Buxtehude, the greatest figure in 
                  German music before Bach. No details have been released of the 
                  exact total number of releases which there will ultimately be. 
                  However a good estimate is that we are over half way through. 
                  There may well be about two dozen volumes. 
                  
                  This is the second volume of Buxtehude's chamber music, the 
                  lovely Trio Sonatas Op. 1 (BuxWV 252 - BuxWV 258), led by Ton 
                  Koopman (keyboards), whose project this is. The first collection, 
                  actually Volume XII (on Challenge Classics CC72251), featured 
                  works only (previously) available in manuscript. The seven sonatas 
                  published as Buxtehude's Op. 1 are for violin, viola da gamba 
                  and basso continuo. 
                  
                  They're the first of two pairs of such sets - with seven apiece 
                  - published in the 1690s. It was Giovanni Legrenzi (1626 - 1690) 
                  who did as much as anyone to introduce the trio sonata to the 
                  Baltic cities - in one of which (Lübeck) Buxtehude was based 
                  for so long. 
                  
                  Buxtehude responded with warmth and enthusiasm and extended 
                  his own repertoire to include more instrumental and chamber 
                  music towards the end of his life than before. What we hear 
                  on this CD is testament to Buxtehude's immense skill, originality, 
                  and ability to take a format, a relatively new genre, and make 
                  of it something special, intriguing, entertaining and completely 
                  delightful. Above all something of great beauty and originality. 
                  
                  
                  That basso continuo, according to the title page, was originally 
                  intended to be the harpsichord. But since we know that this 
                  type of repertoire was often performed at Buxtehude's Marienkirche 
                  at Lübeck (perhaps as offertory music), Koopman has allowed 
                  himself the latitude of adding/supplementing an organ and lute. 
                  And very sweet and winning they sound. 
                  
                  There is a gentleness and directness in the melodies and textures. 
                  There's nothing sensational for all the 'inherited' colour of 
                  the form's Italian origins. Specifically, there is less of a 
                  sense of doubling, of layers of sounds in the same tessitura, 
                  than was the case in the earlier works of Corelli in particular. 
                  This tends to create a rather rich feel to the music … listen 
                  to the opening of the B Flat (number 4) [tr.4], for example: 
                  there are lines chasing lines, counterpoint up and down the 
                  scales, textural mirroring and much intersection and interplay 
                  of timbre and harmony. It's almost as though there were half 
                  a dozen instruments. 
                  
                  But these players are so totally in control of the base score, 
                  the ornamentation and the extemporisation - which Buxtehude 
                  would have expected - that they never get carried away, never 
                  indulge inappropriate melodic ideas. Rather, they lead us from 
                  one felicitous passage to another. For all the fantasy, the 
                  melodiousness and concentration of the north German style stamped 
                  by Buxtehude on every bar, there are still many Italianate sentiments 
                  … towards the end of number 5 in C [tr.5], for instance, and 
                  the repetitive ostinati in the middle of the next piece, in 
                  D [tr.6]. This variety is handled with consistency and grace 
                  by each of the players in their own way. 
                  
                  Interestingly, Koopman explains that Buxtehude's choice of seven, 
                  rather than the more usual half dozen, sonatas reflects the 
                  German preference for multiples of the septimal system as found 
                  in the Bible and in cosmology… seven days a week, the three-score 
                  years and ten of our lives, the seven then known planets. But 
                  this music is as substantial and far from fetishistic as can 
                  be. And a delight from start to finish. 
                  
                  If you're collecting the Challenge series, you should have no 
                  hesitation at all in getting this desirable and stimulating 
                  CD immediately. Similarly, if you have any affection at all 
                  for the best of early Baroque instrumental music and/or for 
                  one if its most original composers, this issue is one not to 
                  be missed. Superb playing of wonderfully inventive music.
