Part 4/8:
A fundamental aspect of music composition is the creation of chords. The simplest chord follows the 1-3-5 pattern, which corresponds to playing the first, third, and fifth notes of the scale together. In contrast, playing the same shape starting from a different note, such as A, creates an A minor chord. Thus, chords can sound distinctly different despite being played in similar formations due to the arrangement of the intervals—namely the distance between their notes.
