Jan Stockigt discusses a number of the existing psalms in her book. That makes me look forward to them! They all cleverly suit the texts, but are mostly pretty compact, as l'infastido notes. If you want to get a glimpse, the best way is through SLUB & IMSLP.org. You can also hear a couple on the 'audio' section of jdzelenka.net.
Missing Psalms
Out of all of the cycles, this one has suffered the most missing manuscripts. The history of those missing pieces is interesting, as according to the 1765 catalogue compiled under Schürer, the autographs were already missing. Only the parts still survived (which therefore presumably still made them playable for the Hofkapelle). That is why we no longer have them, because almost all part-books were taken from the city in 1945 during the Soviet 'liberation'.
These missing psalms together could technically make a complete 'Vespers for the Blessed Virgin' ('della Beata Virgine' like the famous set by Monteverdi). Interesting to note is that the Dixit and Magnificat are both in minor keys, which is different to previous cycles. Also, the Magnificat is SSATB and 'instrumenti ad libitum'. The loss of this set of psalms is so tragic and tantalising to fantasise about... if and when these are recovered from their hiding place in Russia, they should make a nice stand-alone recording!
