Looking at one ‘note’ at a time doesn’t change the equation, it just makes it easier for us to look at it and understand it. So for understanding, it’s much easier to look at the frequencies one at a time. But that doesn’t change the fact that it’s composed of individual tones. And the higher related frequencies, the harmonics, of 880, 1320, 1760, 2200hz complete the musical sound we hear.īut it’s the fundamental that what we call the actual note. And when you use a tone generator or test disc to generate a sine wave of say 440hz, it’s the fundamental note alone without harmonics.Of course music is composed of thousands of frequencies all sounding at once. In the case of middle A for example, it’s 440 Hertz. ![]() And like other perceptions, we actually construct the combination of sounds in our brains.When we hear a note like middle A on a piano, a complex set of oscillations are transmitted through the air to our ears. It’s the harmonics that allow you to know the difference between one instrument and another.Of course if you strike a string like a piano (yes it is a percussion instrument), pluck a guitar, or draw a bow over a cello, you’ll have additional clues to work with.But we perceive the notes on a musical instrument or sung by a vocalist by combining fundamental and harmonic tones. Musical ‘notes’ are made up of fundamental tones (frequencies) and harmonics. Equalizer And Frequency Equalization Tutorialįirst a word about Fundamental Frequencies and Harmonics. ![]()
