Help! I have an adult pupil in his 50s who appears to lack confidence in regard to musicality. He is capable as a player: he picks up technique well, he is interested in the music and he appears to put a decent amount of practising time in. However, when it comes to expression, he seems very reluctant to do so musically. He listens intently, and if we isolate a bar, a note, etc. and I get him to play it in different ways as a means of applying dynamics, etc., he can do it capably. However, he seems very nervous when he plays and falls into a "comfortable" mezzoforte with little or no variation. He is quite scientific, seems to be very left-brained and certainly is far more interested in the specific mechanics of technique than the comparatively nebulous area of musicality.
My concern now is to find ways to increase his confidence in regard to musicality, and I wondered if any of you had any advice please?
