Cobblestone
Schusterterzen describes a special kind of accompaniment in music . A second voice is added to a melody , which is a third below the melody tone.
Whether the cobblestone ore is a "major" or a "minor" third determines the position of the sounding interval in the corresponding accompanying harmony.
In order for a melody to be continuously harmoniously accompanied with thirds, the melody tone must not be the basic tone of the accompanying harmony (for example possible in the refrain of the song Down in the green meadow ).
If, however, a major sixth is added to the accompanying harmony in addition to the fifth ( sixte ajoutée ), the keynote of this harmony can also be part of the melody.
