MUSIC THEORY – The Missing Fundamental

In this music theory animated tutorial made by Walk That Bass, you are going to learn what happens if we remove the fundamental frequency of a note.

“We learned in a previous lesson that the pitch of a note is determined by its fundamental frequency, even though it may have numerous overtones. Now, not all the harmonics need active. If a note is missing a harmonic, it doesn’t affect the pitch of the note – but only affects the timbre. This is why plucking a guitar string in different places sounds different.

If we take the note A at 110 Hz, then the harmonics that we would hear would be multiples of the fundamental frequency. So 110, 220, 330, 440, and so on. But if we were missing the 3rd overtone (440 Hz) we would still hear the note A at 110 Hz – it would just have a slightly different timbre. There could be several silent harmonics—and still the fundamental frequency would be 110 Hz.

But what happens if we remove the fundamental frequency? What note would this sound like? Interestingly, even though the fundamental frequency is missing, this note would sound like an ‘A’ with a frequency of 110 Hz. This is because those five frequencies only repeat their collective cycle or overall pattern 110 times per second.” (Credit : Walk That Bass)
