Sebastian Anton Schere was a German organist and composer who lived from 1631 - 1712. In 1671 he became organist of the cathedral in Ulm and remained there till his death. Only a few compositions of Scherer survived till today. Among them is a volume titled "Intonationes breves per octo Tonos" and contains 32 short versets, four for each church mode.
Karges was somehow familiar with these Intonationes breves, as he used several of them as basis for Capricio's and one Ricercar. Just as with Karges adap'tation of Roberday's fugue I published three days ago (https://partitura.org/index.php/wilhelm-karges-francois-roberday-capricio-in-g/). Karges adapts Scherer's material to create a piece consisting of several movements, that often has the characteristics of a prelude and fugue of the early baroque.
Karges' Capricio Sexti Toni is based on Sebastian Anton Scherer's Intonatio Secunda Sexti Toni and Intonatio Quarta Sexti Toni. To the Intonatio Secunda Sexti Toni Karges adds 6 bars to create a somewhat stronger end to the piece. To the Intonatio Quarta Sexti Toni Karges adds a handy repeat. He probably did so to be able to elongate the playing when the circumstances in the church service needed a longer bit of music than just playing it once would create.
The recording was done with the Hauptwerk software and the sampleset, made by Sonus Paradisi, of the Hinsz organ in the Reformed church in the Midwolda (http://www.sonusparadisi.cz/en/organs/netherlands/midwolda-surround-sample-set.html). I play the repeat of the Intonatio Quarta Sexti Toni as well.
