notes and frequency

Discussion in 'General Instruction [BG]' started by Davidoc, Mar 25, 2002.

  1. Can anyone tell me why (scientifically) Notes in the different octaves sound the same? Does something happen that makes them sound equal at different freqency intervals?

    Why does low A sound like high A?

    I know this is deep and confusing, but it would really help me understand music.

    Part of the reason is that each octave represents a doubling in cycles per second.

    For example A0 is 27.5 Hz, A1 is 55, A2 is 110, A3 is 220, A4 is 440, and so on.
