Harmonizing a Bass Line: Music Theory Class

Inspired by a recent stream, Michael shows you how to harmonize a simple bass line.
It's kind of assumed that you know some basic theory, maybe at least as much as a student would know after their first semester of music theory study.

Welcome! Thanks for watching!

Do the three 'rules' apply also to minor keys? Is this partimento/rule of the octave?

[@ILoveThisBlank]

The three most common root movements do also apply to minor keys! The only thing that will be different will be the qualities of the chords. By rule of the octave, do you mean going up a fourth instead of going down a fifth? If so, yes, that does apply here. In Classical music, basses can make wide leaps pretty easily, so leaping up a sixth instead of down a third is fine, but leaping down a seventh instead of going up a step is usually less common. You tend to want to think of everything as if it's going to be sung, sort of for safety's sake, because if a voice can do it, most instruments should be able to do it.

@@ILoveThisBlank Thanks for replying. AFAIK Rule of the Octave is a collection of ways for harmonising each note of a scale applied to a bassline, popular with baroque and classical eras composers.
