Question

Explain why the wavelength would represent two notes that sound terrible together.

Answer 1

Sounds that are perceived as unpleasant when played together are termed dissonant. The interference of acoustic waves contributes to this dissonance. In an octave, the higher-pitched note has a wavelength that is half as long as the lower note. In the context of scales, envision each note as a Lego brick.
