Question 1: The fourth harmonic vibrates at four times the frequency of the fundamental and sounds a ________ above the third (two octaves above the fundamental).
Perfect fifthPerfect fourthSemitoneInterval (music)

Question 2: If the harmonics are transposed into the span of one ________, they approximate some of the notes in what the West has adopted as the chromatic scale based on the fundamental tone.
FifteenthOctaveSemitoneInterval (music)

Question 3: In terms of frequency (measured in cycles per second, or ________ (Hz) where f is the fundamental frequency), the difference between consecutive harmonics is therefore constant and equal to the fundamental.
Pascal (unit)VoltJouleHertz

Question 4: On the other hand, the octave series is a ________ (2×f, 4×f, 8×f, 16×f, ...), and we hear these distances as "the same" in the sense of musical interval.
