Topic: Menghini's Etudes
I want to recommend Vincenzo Menghini's masterful "18 Studi per Fagotto in preparazione all musica contemporanea" (18 Studies for Bassoon in preparation for contemporary music) published by Scomegna Edizioni Musicali. I find them to be excellent studies for rhythm, varying meters and particularly articulation.
Principal bassoon, Toronto Symphony (1968 - 1985)
