Tuning my new Moon Whisper 42 chromatic

I just got it, and I'm having a hard time tuning it. It did not come with a hammer, but if it did.,I don't think it would move the tines. Also the screws on the lower tier are inaccessible. I could not find anything but the usual instructions on line. I ended up:

  1. loosen screw just enough so the tine moves with effort

  2. move tine

  3. tighten screw

  4. checking pitch

  5. repeat

Very tedious.

I saw another chromatic that had the tine arranged like a piano keyboard. As a beginner, it seems that would be harder to play with thumbs.
