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.
While the scale degrees for the first six notes are the same for both major and minor scales, the seventh one is special. If the seventh note is a half step below the tonic, it is called a leading tone. If the seventh note is a half step below the tonic, it is called a leading note (or âleading toneâ). Play the C Major Scale, notice how the seventh note wants to lead into the tonic. Leading tones also occur in harmonic minor and melodic minor. In natural minor, the seventh note is a whole step below the tonic. In this case, the note is called a subtonic (or âflattened leading noteâ). Play the C Natural Minor scale, notice how the seventh tone lacks the desire to lead into the tonic.
