It is also interesting that many, perhaps most, patients with this condition also have skin allergies, eczema and/or asthma. The patient with moderate to severe icthyosis often has problems sweating due to the buildup of scales on the skin. The scales essentially seal the sweat glands.
For now, it is good to know the names. These names apply to all major and minor scales. 1  1st-Tonic. 2  2nd-Supertonic. 3  3rd-Mediant. 4  4th-Subdominant. 5  5th-Dominant. 6  6th-Submediant. 7  7th-Leading Tone.
Even a perfect 5th is built upon two intervals of thirds (minor-Major or Major-minor). An example of an exception is the suspended chord (6-3 formula) in which the suspended note suspends or replaces the third note in relation to the root note. In terms of proper letter sequencing of chords, a further example is the major b (flat) 5 th (5-3 formula) or major chord flat the 5th.
