    Didn’t Bach write the entire Well Tempered Clavier in celebration when
    modern tuning was invented?

    But can you tune a mayonnaise?

    Just temperament is the term you’re looking for. Tuned this way the piano
    would be perfectly in tune, but only for one key. Electronic instruments
    could easily fix all this out-of-tune-ness but don’t, for some reason.

    This is all based on A=440. Have you calculated your ratios based on other

    Perhaps the imperfection of its harmonics is why I adore the piano so much?
    This oddness of pitch just makes me love it more for the instrument’s

    simple explanation incoming: frequency = how often an event occurs. in the
    case of sound, its how many times the bump part of the sound (the crest)
    hits your eardrum in one second’s time. in monitors, its how many times the
    screen refreshes in one second’s time. both are measured in hertz. Hertz is
    how many times an event occurs in one second’s time.

    Sometimes I watch these videos, and even though it’s cool and informative,
    I still don’t understand it…
