10250074814	Phase	Used to describe any part of a sample with uniform composition and properties	2
10250074815	Pitch	A tone's experienced highness or lowness; depends on frequency.	3
10250074816	harmonic spectrum	A spectrum which only contains components which frequencies are whole number multiplied by the fundamental frequency (lowest frequency)	4
10250074817	fundamental frequency	the lowest frequency of vibration of a standing wave	5
10250074818	sound intensity	a measure of how much power a sound transmits	6
10250074819	Timbre	the character or quality of a musical sound or voice as distinct from its pitch and intensity.	7
