Sounds normal to me. The circle shape causes two steppers to oscilate between fast and slow in a sine pattern, and those two stepper speeds are phase shifted compared to each other, making it sound odd.

If you printed an elipse insteaf you’d get a different song.

The sound itself is expected, but it sounds like there might be some resonance at play, increasing the volume, but I wouldn’t worry about it.

yes

You mean the stepper music? That’s normal and especially audible when printing circles.

A little bit noisy, but it really depends on a lot of factors. Firmware and controller board can make a difference in stepper noise, as well as age and friction. If it’s a new printer, check that your firmware is updated, and all your bearings are moving free and smooth. As long as that’s all up to spec, rock on till something doesn’t print.
