What scale did dvořák consider to be common among the folk music of african-american and native american traditions?

pentatonic

Explanation:

Dvořák used popular melodies in his American works. He was inspired by the folk songs of Native American and African American traditions.

And what characteristics did he find in black and Indian music? At least two are the ones that pop out the most - or rather the ears. The first is the use of the pentatonic scale.

The traditional musical scale has seven notes; On the other hand, the pentatonic scale removes two of these notes, exactly those that make up the two semitones of the larger scale, and we get a five-note scale without semitones.

The second common feature is the use of natural sensitivities on the smaller mode scales, making them sound like aeolian mode.

for this case we have the following equation:

we apply distributive property to the terms within parentheses.

subtracting 2 on both sides of the equation:
