e. pitch

People speak about "high" and "low" sounds quite unselfconsciously, as though they know that the latter actually have a low frequency-relatively few cycles-and the former a high frequency. The musical term for this quality of sound, which is recognized as pitch. Low pitches (low frequencies) result from long vibrating elements, high pitches from short ones.

a chromatic scale uses the twelve tones of the octave, while a regular scale only uses eight, or seven different notes (as the first note is played twice)
