Making or getting a rotating stand with strong control over rpm

  1. I require for a project a rotating stand, much like these... ... Which are used in shops

    However as you can see they have some preset rotation speeds which have nothing like the accuracy that I will require. I need to control the speed of rotation down to the second e.g. 9 rotations in one minute.

    If there is something off the shelf that I can get that would be perfect. I don't know if there is something that could link to computer software.

    I am way out of my depth on this stuff - I am a musician and not an engineer, but am willing to put some work into this to get it to work. I can program quite well, so if there are programs that can control hardware that is an option.

    Many thanks for any help :)
