Overtones and Intervals by Bernd Michael Sommer

2015-12-28T15:20:45.273Z

Overtone singing. Bernd Michael Sommer http://www.musik-ist-mehr.de shows you how to sing a part of the overtone series with your normal voice. This helps you to identify the overtones in the overtone series. Featuring the overtone analyzer software by Bodo Maass and Wolfgang Saus.

Obertonsingen. Bernd Michael Sommer von http://www.musik-ist-mehr.de singt einen Teil der Obertonreihe mit der "normalen" Stimme. Das hilft dabei, die Obertöne der Obertonreihe zu identifizieren und musikalisch einzusetzen. Die verwendete Software heißt Overtone Analyzer und wurde von Bodo Maass und Wolfgang Saus entwickelt.

Harmonic Series Spiral

2010-08-10T06:25:35.550Z

A musical animation of the first 16 elements of the harmonic series.
NB! Most computer speaker systems cannot render the deep tones, so use headphones, but be careful as the volume setting is quite high!

Here the tonal points are presented within the frames of an octave spiral structure which illustrates a fundamental principle in music:
The octave is a repetition of an already experienced quality on a new level.
The essence of the graphic spiral is likewise:

1-2-4-8 are octaves of the fundamental;
3-6-12 are octaves of the perfect fifth;
5-10 are octaves of the just major third etc.

The number figures are an attempt to develope a natural and intuitive graphic representation of the inherent structure of number based on factorization, here from 1 to 16.
It is not a 'number system' like our base 10/ decimal system (based on the primes 2 and 5) or a sexigesimal system (primes 2, 3 and 5), but an attempt to come close to the essence of the language inherent in the concept of numbers, a language of primes and compounds - arithmethic (and musical) atoms and molecules.

Proceeding through the spiral no 1-16 the neighbouring intervals grow successively smaller:
1:2=octave;
2:3=perfect fifth;
3:4=perfect fourth;
4:5=just major third;
5:6=just minor third;
6:7=septimal third;
7:8=septimal second;
8:9=major wholetone;
9:10=minor wholetone,....;
15:16=just halftone.

The sounds are sine wave tones. Please notice, that this is not common tempered tuning values but frequencies from the harmonic series with a fundamental of C=64 Hz (no. 1).
The other frequencies are multipla of this tone (nx64 Hz).
The tonal axises represent divisions of a tonal circle of 360 degrees = 1200 musical cents.
Example: The 5-10 axis is situated at 115.8 degrees from the vertical axis corresponding to 386 cents (whereas the equaltempered major third measures 400 cents, corresponding to 120 degrees). More to be found (in danish) on http://www.detspringendepunkt.net

Harmonics # 8-9-10, three different exercises

2010-03-11T21:32:54.202Z

NB! This video refers to an image here on OMN:

This overtone singing exercise has its focus at the accentuating of the elements no 8, 9 and 10 from the harmonic series. The demonstration gives three different ways to do it:
- By using the vowel sounds. Here each element is separated by a [ŋ] sound. The overtones do not stand out very clearly here.
- By overtone technique where the tip of the tongue points the nodes of the relevant overtone near the palate
- Same but here each element is separated by a palatalized n (articulated further back than normal articulation).
The music of the 8-9-10 sequence is the whole tone steps do-re-mi like the first three notes of Frère Jacques/ Are you sleeping.
