I read that the human ear perceives pitch as the logarithm of frequency, so the ear should sense that each note on the scale rises by the same amount. However, to me the higher notes in an octave seem much higher proportionately than the lower ones. I enjoy music and I'm told I have a good singing voice, so what's going on here? Is this a qualia effect where my subjective interpretation of a melody is different to others but we both agree on the objective sound?
For example if I keep adding small constant weights to my hand, my subjective feel is that the increase in load is linear. But with musical notes, the effect is not linear. My subjective feel of the change in pitch as notes go up through the octave is small at the bottom and large at the top.
