Jadwiga Dygulska (born around 1722, in a convent 1739–1796) was the daughter of Jan, a musician from Sandomierz, a psalter of the collegiate church. Highly valued for playing positively, she was a monastery organist for a while; She rewrote two organ books L 1668 and L 1669, the first of which is more extensive and the second is a partial copy of the first. These books, carefully written down, contain organ accompaniment to the mass for various occasions of the liturgical year as well as solo pieces for a keyboard instrument, also intended to be performed during the liturgy. The notation of the mass includes a choral melody in a soprano clef and a bass line, sometimes digitized, intended to be performed as an accompaniment on the organ. The book L 1668 also contains information on the principles of music and 138 pieces for harpsichord or clavichord, many of which are virtuoso in nature. However, there is no significant confirmation as to whether Dygulska was the composer of some of these harpsichord pieces.
Jadwiga Dygulska spent 58 years of her life in the convent, leaving a good and grateful memory, which was expressed in an insert in the book L 1668:
“The book of Writings with Masses and various notes is always given to the Choir, the work of which is Jadwiga Dygulski’s own hands, ZRSOB, left a great memento, therefore it is a duty to remember her soul. , Because probably no one will be able to leave such a beautiful memento of himself. Apart from the Virgin Mary Moszyński and Jadwiga Dygulski. Which books to sing and play are the best for the remembrance and glory of God they have left, for whose souls may the Remembrance of God always be called “.
