bonjour instructables! in this 'ible I will show you how to write a simple melody and accompaniment! you need some musical knowledge! (if anyone wants a how to on music reading and theory just leave a comment and I'll tell you or make another 'ible)

disclaimer: I am using the 12 bar blues chord sequence, and FYI I didn't "invent" it, the melody and final result however is my own!

Step 1: Find a Chord Sequence!

I'll be using the 12 bar blues chord sequence in g major, but you can use your own! the g minor chord sequence above I used for my gcse composition, and I prefer it to the blues, but the blues is VERY easy to compose for!!

12 bar blues in g major:

G | G | G | G
C | C | G | G
D | C | G | G

Step 2: Make a Simple Tune That Covers TWO Bars

this tune will be repeated throughout, mine is


it splits into two bars as:


Step 3: Rhythm!

notate your rhythm, this will help you split it into two bars, and it will tell you your time signature, mines 2/4
you can now replicate this for your other chords
c major:

Step 4: Notating

first wrote your clef (treble in this case for the melody) and your time and key signatures.

as mines in g major it has one sharp - f sharp

Step 5: More Patterns

chose two or more bars to be a "bridge" - i.e. they have a different - or no - pattern. for mine it's bars 9 and 10!

Step 6: More Notating

now write out all the melody you have (minus the bridge which we are yet to write)

Step 7: Bridges!!!

improvise a bridge,

Step 8: Notating Galore!!

now write in your bridge, and tweak anything you don't like!

Step 9: Left Hand Time!! (bass Clef)

now we need to make an accompaniment; the simplest way is to take the bar's chord and choose 1-3 notes from it:
e.g. for g major you could use the notes G B D
for c major C E G

Step 10: Write It!!

Picture of Write It!!

write in your accompaniment with whatever rhythm you like (sometimes simple is the best) and you're done! (you can add dynamics etc now!)

you've got a little bit of blues under your belt!!


please leave a comment if you need any clarification or you want to give some feedback!! it would be appreciated!! thanks for reading!!
