Document Summary
Auditory scene analysis: music: pitch (similar to frequency- vibrations) If they are too high or low, we cannot hear frequencies. 440 hz tone- a note is just a tone you have given a name to (a) If we look at 880 hz, it is also a, and is separated by an octave: octave equivalence: an integer multiple of a frequency (a 440 and a 880 are separated by an octave, 880 = Scale: number of chunks that an octave is broken into: diatonic: 7, pentatonic: 5, chromatic: 12. Pitch height: think of what octave number you are at, the higher the octave, the higher the pitch height: a1 and a2 have different pitch heights. Chroma: within an octave, the position of the tone: a1 and a2 have the same chroma. Constraints: people have to be able to discriminate between two notes/chunks (1% is about the minimum). In a normal scale, it is around 5%
