Tuning Note: I have been checking the factory tuning of my A-34C, after having played it for a while. I checked at A=440 through A=443, and it is closest to A=441, so I’ve decided to use that standard for this melodica. After repeated readings in relation to 441, I find only seven keys that are more than 3 cents off, only three that are more than 6 cents off, and just one that’s terribly off, G4 at 16 cents flat. So I will tune just those seven keys. Pretty good factory tuning, in my opinion, except for the G4.
