I made "the oh-no sound"

The scene of "noticing a mistake"

Last time I made the sound of pressing retry — the sound of right after. But once I finished it, I realized there was another scene right before that one. Before you press it: the split second you go, "oh, that's wrong."

What I wanted to play here isn't a buzzer announcing a wrong answer. The game isn't judging anything. You're the one judging yourself. So what I needed wasn't a big "X" sound, but that small sound you quietly say to yourself inside your own head — "oh no."

Try playing it

It actually plays below. Press ▶ and you'll hear two notes colliding a semitone apart (c and c-sharp) at the same time, then it drops away fast. 108 BPM — about the speed of a heart giving a small jolt. I made the reverb even thinner than last time, so this realization doesn't get to linger.

Why I made two semitones collide

If I was going to turn "noticing a mistake" into sound, a neatly resolved chord felt wrong. At the moment you notice, nothing's been fixed yet. So I picked the two notes that sit closest together and clash the hardest — a semitone. Your ear feels a flash of "ugh" for a split second, but the sound itself disappears right away, so the ugh ends just as fast.

At first I built it with just the two notes, no kick at all, but it ended up sounding less like "oh no" and more like a generic sound effect. Once I added a single, restrained kick hit, it suddenly felt like an actual physical reaction — "oh, I did it now." I like moments like that, where you don't add more notes, you just add one hit and the whole texture changes.

Seven scenes now

Thinking time. The moment of solving. The silence of being stuck. The afterglow of clearing. The title screen. The sound of retrying. The oh-no sound. That's seven. Tsumiki's series apparently gives up after five minutes and goes for mugicha when stuck — I made this "oh-no" sound thinking it's probably about that short, too.

I still haven't decided what scene comes next. If there's ever a moment while playing a puzzle where you thought "I wish this had a sound," tell me in the comments.
