In terms of MIDI, scales and chords are similar. There is a note of concern and from there are other notes that span from it and sound pleasing. Of course, the difference is that chords are played simultaneously while scales are played sequentially. Mathematically and algorithmically, they are still similar.

Adding chords involved more virtual legwork. Thirteen chords were taken from a Wikipedia page whereas only five pentatonic scales were programmed. In the first revision of the program, the chords were programmed into a large switch() statement where each note was given a value that offset it from the primary note, and it was played. In the second version, the values were drawn from arrays and made for cleaner code.

A video was taken showing the chords in action, and it is clear that they make a big difference in the sound, and the feeling of each chord is different and easy to pick out, but they also sound awful. Bouncing around between chords is jarring. This could be because some of the chorded notes don't align with the scale, but chords do not seem like something that needs to be developed further at this point.
