  • Rachel Michaux
    Rachel Michaux

    Wow, this was a 'prank'? I don't think you know what 'prank' actually means. The pianist clearly knows how to play, and your augmentation of the instrument didn't change her competence. Again, do you know what 'prank' means? I think it backfired on you.

  • Jason Wright

    The First Lady... Phenominal! 💛 I think you need to give her a second chance after you fix the broken keys and maybe lighten up the hammers for better playability. Ya know... I think the second gal should definitely be given another shot. Wow!💛💛💛 Oh.. Wow... Wasn't expecting a 3rd pianist ... Give her another go on that beast after it has been fine tuned.

    I have to admit I love the way it sounds!

  • Erik

    Also, I think to give you some context -- classical pianists/musicians will meet this sort of shit in their normal education too. This isn't a novel idea (the hammers being altered). Composers (especially modern ones) will alter the piano in different ways. We call these "extended techniques" as a broad term for any way that a composer changes the way a musician plays their instrument. It could be something like an electric guitar playing by using a hammer on the strings, a harpist bowing their strings, or even making a pianist pluck the strings instead of playing with the keys.

  • Erik

    Thank you for supporting the arts though lol

  • Erik

    Sounds like a dulcimer lol.

  • Uub Willemse-Jacobson
    Uub Willemse-Jacobson

    Contemporary composers ask for modifications to instruments all the time. Usually nothing as drastic as what you did, but professional musicians will be far more used to expecting the unexpected than you'd expect.

  • Dyanlee

    It sounded really amazing. But you can easily see the pianist struggling with the heavily weighted keys.

  • Seth Van Swircaa
    Seth Van Swircaa

    The first pianist was amazing even with the extra key weight and hence the timing issue. The second pianist seemed like such an awesome person and was very talented ... She was also scared that you might murder her for at least the first half of her being there... Look at her face when you say so you can cut it later.... That's the look of someone trying to play it cool.. lol She didn't know why you were so nervous and I'm willing to bet that the back of her mind jumped to the worst conclusions first. But once she knew you weren't a psycho killer it seems like she really had a good time and got paid for it. " You wont read this anyway (I'm an engineer)" lmao..... The third pianist would have probably been more nervous but she seemed to be confident that she could kick your ass if she had to lol... And as for the engineer; another brilliant creation.. Some stronger hammer springs for faster playing and this thing is completely awesome.

  • JoanKSX
