TL;DR: An octave is a *ratio* (×2), not a fixed Hz step. A log slider matches that, so the control feels fair across low and high pitches.
Key idea: pitch steps feel multiplicative. Your ear cares about ratios more than raw Hz differences
Common mistakes: expecting equal Hz steps to feel equal, and blaming your ears when the UI scale is the real problem
Most people think of pitch as “higher or lower,” not as raw Hz. That matters because your ears respond more to frequency ratios than to frequency differences.
A simple example: 200 Hz → 400 Hz is an octave. 400 Hz → 800 Hz is also an octave. The *difference* in Hz doubled (200 vs 400), but the perceived pitch jump is the same. That’s the core reason linear sliders feel wrong for pitch tasks.
In Dialed Sound Game, the slider is logarithmic so that equal distances on the screen roughly correspond to equal perceived pitch steps. That makes the game feel fair: a small nudge at the top doesn’t explode into a wildly different sound compared to the same nudge at the bottom.
If you’ve ever used an EQ or synth, you’ve seen the same idea: frequency knobs are often logarithmic. Human perception compresses the low end and stretches the high end. A control that matches perception is easier to learn and easier to improve on.
There’s also a scoring angle. If you score linearly in Hz, the high end becomes brutally sensitive and the low end becomes too forgiving (or vice versa, depending on how you tune it). Log scaling makes “closeness” more consistent across the band.
A good mental model is: pitch lives on a musical ruler (octaves, semitones), while Hz is a physics ruler. Both are valid, but a game about remembering pitch usually wants the musical ruler.
What to track: notice whether you overshoot more at the top than the bottom. If yes, your mental model is still linear
Do: bracket low/high, then split the difference
Avoid: making five tiny micro-moves in a row without re-centering your guess
If you want to feel the difference yourself, try a few runs and notice how “small” moves behave at low vs high pitches: Play the frequency game.

Practical takeaway: if a pitch slider feels jumpy or impossible, it’s often the UI scale — not your ears. A log slider reduces that friction so players can focus on memory and listening, not fighting the control.
