    Metal tube instrument notes are flat and out of tune

    My tuner only can tell me what notes I have, give or take 50 Hz. So we could take a really rough estimate. I had G sharp, C, E, F sharp, D-- instead of a regular scale (C, D, E, F, G). So that would be about: 207.65, 261.63, 329.63, 369.99, and 587.33.

    Metal tube instrument notes are flat and out of tune

    The E pipe was actually the exact same one from my original post. :) Lucky coincidence, I guess.

    Metal tube instrument notes are flat and out of tune

    I did manage to somehow by chance get an E pipe that actually produces an E. So here is my question, can I use this equation to solve for the other pipes relative to my E: L2 = L1 * sqrt(f1 / f2), where L2 is the length I'm solving for, L1 and F1 are the length and frequency of E, and f2 is the...

    Metal tube instrument notes are flat and out of tune

    That's actually a grand idea... I was so fixated on the idea of a xylophone-like instrument that I hadn't even thought of arranging the thing more like wind chimes. I think I'll go ahead and try that with tape and see if it helps me to get a more accurate sound. In the meantime-- and thank...

    Metal tube instrument notes are flat and out of tune

    Ah, I see about the vibrational nodes... I actually have been trying with them both on the floor and resting on parallel wooden dowels. I was wary of attaching anything permanently while my project is still so out of whack, so that part of the design is not set in stone. Sorry to ask for more...

    Metal tube instrument notes are flat and out of tune

    (1) My requirement for this project was to build an instrument that can produce all the notes in a C scale. The accuracy of the notes is to be judged through Frequency (Hertz). I decided to build an instrument whose design is comprised of eight electrical conduit tubes (metal) that are about...
