Harmonics # 8-9-10, three different exercises

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.
