An overtone is any frequency greater than the fundamental frequency of a sound. Using the model of Fourier analysis, the fundamental and the overtones together are called partials. Harmonics, or more precisely, harmonic partials, are partials whose frequencies are integer multiples of the fundamental (including the fundamental which is 1 times itself). These overlapping terms are variously used when discussing the acoustic behavior of musical instruments. (See etymology below.) The model of Fourier analysis provides for the inclusion of inharmonic partials, which are partials whose frequencies are not whole-number ratios of the fundamental (such as 1.1 or 2.14179).
When a resonant system such as a blown pipe or plucked string is excited, a number of overtones may be produced along with the fundamental tone. In simple cases, such as for most musical instruments, the frequencies of these tones are the same as (or close to) the harmonics. Examples of exceptions include the circular drum, – a timpani whose first overtone is about 1.6 times its fundamental resonance frequency, gongs and cymbals, and brass instruments. The human vocal tract is able to produce highly variable amplitudes of the overtones, called formants, which define different vowels.
And it's not just a game
You can't throw me away
I put all I had on the line
And I give and you take
And I played the high stakes
I've won and I've lost
But, I'm fine
Hear me say I'll rise up 'til the end
Hear me say I'll stand up for my friends
And I crash to the ground
And it's just my own sound
I drop in the blink of an eye
I'm colorblind
And your milky way fight
Won't stop my delight
You keep me and lock me away
And it's dark and it's bright
It's your colorful pride that kept me here 9000 days
Hear me say I'll see the sky again
Hear me say I'll die for you my friend
There's a noise in the crowd
But it's just my own shout
I stumble I fall and I pray
Hear you say your eyes see green again
In the end we'll lift our golden hands
Yes, we'll spark, you and I
We'll be colorblind
And these are the lives we gave
Hear me say I'll rise up 'til the end
Hear me say that I'll stand beside my friends
I won't stay on the floor
I will settle the score
I’ll stumble I’ll fall and I’ll pray
Hear me say it's time we stopped our hate
Eye to eye we see a different fate
Yes we we've conquered the war
With love at the core
I stumble I fall, but I'll stay
