Written by Ferdinand Gillet a brilliant Oboe professor this Twenty-minute study is a set of daily exercises for Oboe players. Each exercise is a bit less than a page length and focuses on fundamentals such as trills arpeggios register changes in major and minor keys velocity and most difficult intervals. This set of exercises would definitely benefit upper intermediate/advanced Oboists and is a really good method to increase technical skills. Ferdinand Gillet (1882-1980) was also the main soloist at the Boston Symphony Orchestra. He also wrote a method called studies for the advanced teachingof the Oboe and Exercises for advanced Oboe technique
