My Pro Songwriting Theory Course: My Patreon: Writing a 4 part harmony can be very difficult if you don't understand the basic principles behind voice leading and arrangement. There are countless rules one must follow to emulate the stylings of Bach, Mozart, and Beethoven. But these rules are not needed just to arrange a simple progression! This video goes through the fundamental concepts of harmony and arrangment without getting into the weeds of clefs, notation, and actual “rules“. By the end of the lesson, you should be able to arrange any chord progression for other instruments, and hopefully get new insight into the sorts of complex harmonies that can exist within a chord progression. Thank you to my Patreon Supporters for all their help and kind words. They deserve as much credit for this channel as I do! TAKE NOTE: The arrangement I make in this video at the end violates several golden rules. For one, it includes parallel fifths (parallel motion that occurs a perfect fifth apart). As a teacher who lives in the year 2022, I don't want you to burden yourself with these rules unless you're trying to sound like music from the “common practice era“, or unless you're trying to pass tests in music school (or if you're just really curious). On Parallel Motion: If both voices are moving together in the same interval class, it's parallel. If one voice moves up a m3 while the other moves up a M3, those are both THIRDS. The motion is parallel. If one voice moves up a m3 while the other moves up a fourth, those are no longer the same interval class (thirds and fourths), and would not be called parallel motion, but instead would be called similar motion. Professional arrangement and orchestration takes many more skills than just learning to voice lead. A real arranger/composer will keep in mind the range of the instrument and has to notate music in different clefs. Arrangers also take note of the tonal qualities of instruments and exploit their frequency spectrum to either blend well together or clash and sound juxtaposed. So this lesson won't turn you into a pro arranger - but it WILL get you writing your first 3 and 4 part harmonies and I think it's a great start to composing more advanced harmony. I highly advise you combine this lesson with my last lesson on harmony, found here I also suggest you consider how many more options you will have when writing your voices if you are comfortable with your diatonic seventh chords, inversions, and secondary dominants. Seventh Chords: Inverted Chords: Secondary Dominants: If you know all this stuff, you'll know exactly how I wrote this arrangement! Also, I said at 17:50ish that there is only one way to play that E7 on guitar. But there is another.... 00:00 Intro 01:51 Basic Concepts 06:15 Arranging in 3 voices 10:50 Why the V become V7 13:10 Arranging in 4 voices 16:20 Make It Into MUSIC! 19:41 Outro
