In 2012 the Akademia Muzyczna im. Karola Lipińskiego in Wrocław launched the series Psalate synetos with Wybrane zagadnienia akompaniamentu liturgicznego (Selected problems of liturgical accompaniment, ISBN 978-83-86543-69-2), edited by Marta Kierska-Witczak. The series is dedicated to church music and is addressed to organ students and others who wish to widen their scope of knowledge and practical skills.
The first volume combines contemporary church music theory and practice. Its 16 essays are divided into two groups: Chorał gregoriański źródłem odniesień dla nowożytnej muzyki liturgicznej (Gregorian chant as a source of reference for modern liturgical music) and Historyczny, estetyczny oraz praktyczny wymiar akompaniamentu liturgicznego i liturgicznej improwizacji organowej (Historical, aesthetic, and practical aspects of liturgical accompaniment and liturgical organ improvisation). The table of contents is here.
