Because that is how harmonics are defined!
They're called "harmonics".
The fundamental = 1st harmonic is not an overtone!Fundamental frequency = 1st harmonic.The following tones have a higher frequency:2nd harmonic = 1st overtone.3rd harmonic = 2nd overtone.4th harmonic = 3rd overtone.5th harmonic = 4th overtone.6th harmonic = 5th overtone.Look at the link: "Calculations of Harmonics from Fundamental Frequency".
The frequencies of the harmonics are integer multiples of the natural frequency.
It is three times the fundamental frequency. Scroll down to related links and look at "Calculations of Harmonics from Fundamental Frequency".
Harmonic Series
Harmonics are multiples of the fundamental frequency of the wave.
These are known as harmonics, or overtones.
They're called "harmonics".
That are harmonics: fundamental + overtones. Calculations of harmonics from fundamental frequency. Look down to the related links: "Harmonics Calculator".
For a waveform containing harmonics, the harmonic frequencies are multiples of what is known as the 'fundamental' frequency. For example, for a waveform that contains 'third harmonics', the fundamental frequency is one-third the frequency of the harmonics. The fundamental frequency of vocal folds the speech mechanism as sound generator.

"pitch" is usually taken to be the fundamental frequency. This is the lowest frequency. For a pure sin wave this is the same. Most signals, sounds, are not sinusoidal, pure sin waves. They have harmonics: they have a different shape. The harmonics are (in theory) all multiples of the lowest frequency. Many waveforms you see, tend to have a symmetry that means there are no appreciable even harmonics, so you get 1, 3, 5, 7, ... times the fundamental, the pitch. For these you can do a lot of the strengths of the harmonics. The fundamental frequency, the lowest one is the pitch.
Fundamental frequency.
It depends on the fundamental frequency. If for example you wanted to find how many harmonics a 20 Hz sound has then its all the integer multiples of that frequency which are still within hearing range, i.e 20000 Hz. For 20 Hz this is 20000/20 = 1000 harmonics.
Harmonics are a multiple of the fundamental frequency. If the power frequency is 60Hz, harmonics occur at 120Hz, 180Hz, 240Hz, etc.
harmonics is nothing but an unwanted noise or ripples.A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency. If the fundamental frequency is f, the harmonics have frequencies f, 2f, 3f, 4f, etc. For example, if the fundamental frequency is 50Hz, the frequencies of the harmonics are: 50 Hz, 100 Hz, 150 Hz, 200 Hz, etc. Don't forget: Even harmonics 2f, 4f, 6f,... are odd overtones. Odd harmonics f, 3f, 5f,... are even overtones. Scroll down to related links and look at "Calculations of harmonics from fundamental frequency".
