Lately I’ve been doing some clarinet work out of the Jeanjean Vade-Mecum. The title page translates charmingly to:
“Vade-Mecum” of the Clarinet-player
6 SPECIAL STUDIES
render the fingers and tongue rapidly supple
But this is what really sold me:
The aim of these 6 standard-studies (combining the essential parts generally contained in several exercise books) is to prepare instrumentalists in a very short space of time (about 1/2 hour) when, due to their occupations, they are not able to devote the time necessary for developed exercises and must nevertheless be ready to execute difficult passages, from the standpoint of lips, tongue and fingers.
The movements to which these Studies oblige the clarinet-player to submit will rapidly overcome those imperfections, the diminution or the passing weakness that might result from either fatigue or irregularity of technical work.
“…not able to devote the time necessary … and must nevertheless be ready to execute difficult passages…” This, in a nutshell, is the quandary of the woodwind doubler.
