As many piccolo players know, tuning can be a wreck on piccolos. I play piccolo just for my high school’s marching band and I’ve always have had tuning problems even when I got a new one. I thought it was the piccolo but even my flute teacher couldn’t figure out what was wrong. She watched me play and said my ombouchureembouchure didn’t change when I switched octivesoctaves. I would tune to A, per usual, and it would be in tune. Then I play a middle register F and it goes so flat on the tuner that it’s the furthest away from being in tune. My F, F#, D, E, etc. are all the same. And everything from around C above the staff to the highest extent is fine. So then I tuned to F. All of the notes I was previously having trouble with were in tune but now A and all the others are sharp. Not as drastically as F but I still have to roll in a bit. And of course with marching band and weather, this can be an inconvenience. I have yet to come across someone who has had the same problems as I have and I’m really concerned. I highly doubt it’s my piccolo considering it’s only about a year old and kept in good condition. I also got it recently touched up at the repair shop. I had these same problems on my old piccolo too. So it must be me but my flute teacher can’t identify anything and I don’t know what to do.
