In the Melodic Form, how are the 6th and 7th notes treated on the way down?

In the context of melodic form, when descending through a scale, the treatment of the 6th and 7th notes often follows a specific pattern. The 6th note of the scale is typically lowered by a semi-tone, which aligns with the tonal movement when descending. Additionally, the 7th note, which is often a leading tone, is also lowered by a semi-tone, though this particular treatment can depend on the harmonic context, favoring a more consonant sound when descending.

This practice is rooted in the structure of the major scale, where, on the way down, the 6th and 7th notes transition to their corresponding notes in a natural minor scale pattern. In the case of the natural minor scale, both notes appear lower than their major counterparts. Therefore, the answer indicating that both notes are lowered a semi-tone appropriately describes this descent in a typical melodic framework. Understanding this treatment helps in recognizing patterns in melody construction and ear training within Western music theory.
