transfer, Hoherlegung/Tieferlegung. A shift of a note
or linear progression from one
register to a higher or lower register, usually for some aritstic
or contrapuntal purpose. At deeper levels, such transfers represent
motions away from the obligatory register.
In the example, from Variation 22, notes of an inner voice
are shifted up one octave, above the main linear progression. The octave
transfers are indicated by broken diagonal lines.
