My source was:
Musica Boemica per Organo.
From the preface by Dr. Čeněk Gardavský :
„… For his final examination at the Prague Organ School in 1859 he (Dvorak) had composed for the organ: five preludes (D major, G major, A minor, B flat major, and D major), two little fugues in D major, and a fugue in G major. ...“.
And fom the preface by Reinberger:
“The manuscript of Dvorak's compositions, the phrasing of which has been completed in the present edition, is in the archivs of the Prague Conservatoire.“
I don't know what 'completed' means in this case. So I better omitted all phrasings. --Ralph Theo Misch 00:11, 1 December 2010 (UTC)
