I notice from the General Regulations for Bowed Strings that you're not required to tune your own instrument until Grade 6 (several years downline for me). But my question is this: at Grade 6, are you *required* to tune perfect fifths by ear, starting from the highest string with pitch referenced by the piano? Or is it considered acceptable to tune equal-temperament fifths using an electric tuner (though adjusting for the piano if it's not at A=440 Hz). A third alternative I guess would be to tune each string directly to the corresponding note on the piano?
At lower grades, is it OK for me to take the electric tuner along and tune ET fifths?
Anyway, I guess this is a minor concern at my level: it's just out of interest really.
Many thanks!
