Harmonics, partials, overtones & fundamentals

[Halfers]

I assumed he meant the silliness?

The fundamentals of silliness?

I'm intrigued...

No just fundamentally silly.

 

[Hipparion]

Silliness is fundamentally strong within the human species, and it's overtones are quite well distributed. But to be fair, just as with art, harmonious minds fundamentally need it... life would be quite tragic otherwise.

 

[Targa]

I'm not having things getting silly.

Well spake

Let me digress a moment. Let it never be said that I let things go easily. Looking through my files of acoustic studies I found this chart that compares the harmonic spectrum of F#2 played using different fingerings. It should be noted that F#2 played as the 3rd harmonic of low B has a spectrum quite similar to F#2 played on a "shorter tube" FWIW.

 

[Dibbs]

It has the came harmonic components, as you would expect, but the relative strengths are very different, which you'd also expect since they are tonally quite different.

It seems to me that in addition to fingerings, it is the particular relative strengths of the harmonics that gives various saxophones their characteristic sound.

Saxophones, hoover tubes and every other sound phenomenon!

Me too.

Here's a previous chart you posted:

While staring at the chart, it occurred to me that the peaks resembled a sort of scale. So I played a chord made up of just B1 harmonics (rearranging and changing octaves):

B C# D# F# A

Not sure what the significance of this is, if any, but the chord sounds interesting.

 

[Zugzwang]

Too late. I've read it all now.

Sorry for bailing....
(but you've got to know when to walk away...)

B9.

 

[Admitone]

B9.

And C9 would be for C1, and D9 for D1, etc. So could there be something special about the 9th?

@jbtsax may I ask which software you use to analyze and chart the sound spectra? Your graphs look nice and clean.

Virtins Technology If I remember correctly I purchased the "Multi Instrument Standard". I haven't used it in a long time and it appears I will have to purchase a new code if they don't have proof of purchase in their records.

 

[Admitone]

Audacity is free and it can display the spectrum.

Thanks for the tips! But still looking for Mac/iOS options...

You mean like this?
