I'm trying to play A Cruel Angel's Thesis on the guitar (just the chords for now) and the whole pre-chorus uses lots of 7th chords, and a Ddim7 right before the end. That chord sounds just terrible when I play it.
I know it's dissonant, and I understand how it makes sense harmonically to have tension right before the chorus where that tension is released with perfect triads, and I thought it was ok to have a dissonant chord there.
But I listened to the original song again, and I listened to covers (the end of the pre-chorus is at around 1:04), and I can't here a part with such a strongly dissonant chord. Either they're not playing it (the ultimate-guitar source could be wrong and they could be playing another chord), or they're playing it in a different way, maybe?
How should I approach this chord? (Currently I'm playing it like this and it's painful to the ears)
