These studies are designed to explore beyond the present limits of Horn technique and are meant to form a contemporary extension to the older studies of Kopprasch, Gallay, Maxime-Aphonse etc. They are therefore written to be very challenging - each Etude concentrates on an immediately identifiable problem of technique and presents it at an almost virtuoso level. This should not put the book 'out of reach' - it is clearly set out and good players can start to become excellent players by practicing these Studies perhaps just a passage at a time at first, hence this book's difficulty rating. The complete pieces should then become a standard part of the advanced player's practice.
Although French (F) Horn is stipulated, a further challenge is provided by transposing studies once they have been learned!
