I made this recording to test how my new smartphone is dealing with different volume levels of the organ. Playing (and occasionally stumbling) through theme and varation no. 1 of Christian Heinrich Rinck's "Choral & Variationen" on "Wer nur den lieben Gott lässt walten". Gedackt 8' + Flöte 4' for the chorale, then Gedackt 8' + Prinzipal 4' + Subbass 16' for the variation.
