Very little is known about Georges Guilhaud other than he was born in 1851, and composed for the oboe. He was a friend of Georges Gillet, Professor of Oboe at the Paris Conservatoire from 1882 until 1920. His Premier Concertino, dedicated to Gillet was selected as the pièce de concours on three occasions.
The three pieces were not written at the same time, Polonaise was written in June 1885 and is a longer composition than the other two, Madrigal and Andante Religieux which were written in June 1887. To my knowledge these pieces have not been published and all performance marks are those of the composer.
