I have a friend who is blind. We were talking last night about guitar tuners and were wondering if there is a tuner on the market for blind or partially sighted musicians. All of the tuners we have seen rely on flashing lights or LED displays. does anyone know of a tuner that operates on a system where a high ptiched beep is heard if the note is sharp, low pitch for flat and contiunous for the actual note? Or any other method for that matter? Pitch pipes are rarely accurate enough and we are aware of tuning forks. but us there an electronic tuner out there that can be used by blind/partially sighted. If not who wants to invent one and make a few bob???
