<p>My son was somewhat similar. He liked playing the piano, but did not like his lessons. At every recital, speaking to the audience, his teacher made the same comment about how my son liked to invent his own fingering - not right, but he somehow got the job done. He now does guitar, but still sits down at the piano now and again and plays.</p>
<p>I'm not a musician myself, but it does seem like formal training (like piano) is still needed, so I like TheDad's suggestion: involve her in the process of hiring a piano teacher. Make sure that she knows that the audition is like her interviewing the prospective teachers - she's in the driver's seat. And trust her judgement on the teachers.</p>
