Being an instrumentalist myself, that REALLY IRKED ME. It hurt to read. Proper technique is oh-so-important! They won't keep their wrists in tact for long if they continue like that.
I feel the author skimmed wikipedia and wrote their script with a terminology glossary in another tab. Like giving the definitions for piano and forte at the beginning? Felt somewhat redundant. That could just be me though.
Yees. I get that it's difficult to truly understand something you don't have experience in yourself, but that's where you use a mix of an experienced advisor and cleverly avoiding getting too detailed. Oh well, I'll just have to remind myself that webtoon creators are massively overworked and try not to expect too much from the details. It's a pity, though.
I've only ever heard of that being an undesirable technique, likely to cause hand/wrist problems...
Was that a translation error or are we dealing with a webtoon creator who doesn't have a clue what they're talking about? (Which wouldn't be unusual, but it's so much nicer when they know at least a bit about the playing the piano properly.)
