15 Choral-Vorspiele Op.23 Numbers 13 to 15

15 Choral-Vorspiele using choral motifs, Op.23

Grüel, Eugen Born Pömmelte, Germany, Oct. 5th, 1847; Died. Potsdam, Jan. 4th, 1927.
Organist of the Holy Ghost Church, Potsdam.
That is the only information on this composer that I can find.

The composer takes only a line of the chorale as a theme so for example in #01 the first line is used but in #2 the fifth line is used.
An exception is #13 where the whole of verse one is distributed throughout the relaxed 6/8 piece.

13. Vom Himmel hoch, da komm ich her (moderate agitated)
14. Wie groß ist des Allmächtgen Güte (moderate emotional)
15. Wer nur den lieben Gott läßt walten (quiet and calm)
