Okay, I have mine almost finished...in the process of tuning it now. the fundamental note is F. removing one finger at a time starting at the bottom hole I am tuning it G#, A#, C, D, E, and all open holes is F#. this is the primary tuning I found on a different site. I have a question about my holes. I have noticed as I am tuning each hole starting with the bottom one that my holes are increasing in size as I work my way towards the sounding edge, is this normal? I am on the second to the last hole now and it is very noticeable the size increase from hole to hole as you go up the flute. Is this gonna present a problem when playing? The holes are 1 1/8" apart and in the exact center of the sounding edge and end of my flute. It just looks weird to me.
