I agree, Piantisimo, lose the Bastien - they can ask you if they want to more know.
I would definitely add your degree - some people really care about that.
Also, add 20 years TEACHING experience.
Instead of 'willing' to teach, say that you teach it.
This is what I said:
In a fun and encouraging atmosphere, I can help your child develop skills needed for artistic piano playing, giving them a solid foundation to begin or continue their lifelong relationship with the piano.
Maybe too wordy - but it got the point across. I went on to say:
I have over 30 years (someone said that 40 makes me sound too old) piano experience, including frequent performances as a soloist and accompanist. I was a long time student of the late --------
have attended ---------workshop and am currently enrolled in ------------ where I am learning new teaching methods that I am excited to share with students. I am a member of -------piano teacher's association.
Then I go on to list the focus as a teacher, sight reading, comfort and relaxation, blah blah blah. And I list my price.
Anyway, it got my foot in the door, at least with families in the general neighborhood, and now the word is spreading.
Why don't you get your piano tuned before you start?
