Tune A3A4 by raising or lowering A3 until A3A4 sounds the best according to your ears.
If A3 and A4 do not play together, press PLAY OCTAVE A3A4 and A3 and A4 should sound together.
When you tune a good octave, email me the number below at mark at howtotunepianos.com and I’ll tell you what size octave it is and what the spread is.

October 2016 – I have not had time to give you feedback on your octaves. I apologize. If you have time to help, please contact me.
