Here is our online mandolin tuner by ear, provided with instructions. Note, this tuning method requires a trained ear, nevertheless I recommend you try it, as you may find it a lot easier than expected!
I tested this tuner and managed to tune my mandolin in less than three minutes, and I believe that you could do it too.
If for any reason you find this online mandolin tuner by ear too complex, you may prefer our alternative online mandolin tuner that uses your computer’s or phone’s microphone but requires a Flash Player. This can be found at the following link: Online Mandolin Tuner with Instructions.
Note that the mandolin has string pairs, i.e. both strings should produce the same sound, but we only tune one string at a time.
