Found an article on Deering’s website about melodic scales for the banjo. So, I made a TEF file from it, and tried playing some.
They sounded… weird.
So, I pulled out my tuning app that tells me what the actual notes played are, and found that the fingered notes were all either high or low of the intended note. I checked the open strings tuning, and it was perfect - dead center on the tuning app scale. Checked with a Snark tuner, and also dead on.
What would cause the fretted notes to be so far off? Is it my playing? I tried varying where in the fretted I pressed down. Tried different pressures. The notes continued to be off.
