Musical Intervals
Musical Intervals
A musical interval is the difference in pitch between two sounds. Listen carefully to the following audio clip:
You have just heard 5 sounds. After the first sound, the second one is higher in pitch, the third lower, the fourth even lower and finally the fifth is slightly higher. So, some sounds are higher, some lower and when sounds follow one another as you heard earlier, these pitch differences create musical intervals.
Musical intervals are not produced randomly, there are well defined mathematical ratios between sounds’ pitches (at a physical level we are speaking of sound frequencies, see also the article Musical Sounds)
