Learn how to use simplified rules for 4 part harmony writing to compose your very own piece in this free music composition lesson!
This is all we need to make a great little mini-composition! :)
In this lesson you will learn how to arrange your little piece for 4 parts or "voices".
Simple, easy-peasy 4-part harmony does not have to be complicated. Unless you get stuck in following the rules too much, or by focusing more on analysis than practical and creative work...
(Analysis can be fun, and challenging too, but here we will focus on simply making some music that sound fine with little effort or knowledge!)
When you write 4 part harmony you need to think about the music both vertically and horizontally.
Step 1: Group 2 staff lines together with a bracket. The top staff with a treble clef for the soprano and alto, and the bottom staff with a bass clef for the tenor and bass.
Step 2: Write your melody on top, draw all the stems up. This is for the «soprano» or a high pitched instrument.
Step 3: Add the chord symbols (C, F, G).
Step 4: Draw all the bass (root) notes from your chords. (That is C from the C chord etc.) Stems down. This is the «bass» or the low pitched instrument you're writing for.
Step 5: Time to fill in the other notes from each chord.
Since there are only 3 notes in each chord, and we are writing for 4 different «parts», we will double the root, or the bass note from each chord to get 4.
So, let's look at the score. Hmm...
We have already written two parts. The top note in this example is a C, and the bass is also a C. So, what notes are missing from the first chord?
Right! E and G.
I will try to put G in the second voice, or «alto». Stems down (to help separate the voices visually).
I will give the "tenor" an E. I’ll choose low E for now, since I would cross over the soprano otherwise (and she'd be crossed!: )). Stems up.
Step 6: Next chord. Now, stick to a very easy rule and you will keep a nice smooth sound going:
When selecting the next note for each part, try to use as a small move as possible. Stay on the same note if you can. Be super lazy! The best is to keep the alto and tenor part very «boring».... For now!
In our example the next chord is the Tonic again, in this case a C major chord. The melody has a G, and the bass a C. What’s missing?
Right! Another C (double the root) and an E. The tenor has an E, I'll keep that, but "unfortunately" the alto has to jump a fourth to a C. It is OK, though.
Step 7: Next chord is a Subdominant, or an F major chord. I have A in the melody and F in the bass. I need another F and a C. So, the alto stays on C and the tenor lazily moves a semitone to F. Great!
Continue like this until the end of the melody. It’s a bit like knitting, isn’t it? Check the pattern and how each part moves: As smooth as possible, contrary motion if possible, and no parallel 5ths, 4ths or Octaves.
This was an example of super-simple 4 part harmony. And if you followed along from lesson 1 and lesson 2, you have now you own little composition in your hand. I bet you did it snazzier than the crumpled example above! : )
Now the fun part: You can play or sing through each part, and if you play the piano you can play all at the same time.
If you don't have friends who play different instruments handy, it is great fun to record each part as a separate instrument. You can do this in a notation program like Sibelius, or on a keyboard (I use my Clavinova).
Record each part on a separate track, and then listen to your 4 part harmony composition... impressive!
So, how did it go? Sounded good? Great! Fun, wasn't it?
