[TPIN] Secondary students?

[Steve Wright]

Greetings,

As a college trumpet teacher, I sometimes teach music ed students on their
secondary instrument.  One such student is a clarinet/bass clarinet player
and he is having trouble adapting to a different style of tonguing on the
trumpet.  I can get him to tongue clearly without the instrument, using
what I call "air tonguing", but when the mouthpiece hits his face, he
reverts to a "dooh" or "thooh" sound.

Any suggestions and/or techniques?  I haven't had this problem with a
woodwind player before.

Thanks,

Steve
