The Ten Choral Preludes for Organ are intended for both liturgical purposes and concert performance. For this reason the notation is written in two staves which is not usual for the Organ. The former of the two purposes forced the composer to respect certain limitations of technical complexity so that even an untrained organist could perform the pieces. The themes to each overture are taken from Bohemian Brethren chorales which appear in their original form as brief intonations in the first few bars preceding each overture. The piece was composed in 1971.Contents:O svetlo Trojice svatá / Es geht daher des Tages Schein / Oh Light the HolyTrinity.Ej nuz lacn z zniv / Wohlauf die ihr hungrig seid / Ye Who Are Hungry and Trinity.D ky vzdávám / Ich Dank dir schon durch deinen Sohn / I giv Thank.In Natali Domino.Jiz zasla slunce záre / Hinunter ist der Sonne Schein / The Sunshine Has Departed.Umucen N.
