You need to know only two elements to compose your own melody:

"3JCN notes", and "3JCN rests"

First Step:

Set the tempo

Second Step:

Look at these following examples to know how to write 3jcn notes:

Each 3jcn note contains a first number (common octaves: 5,6,7), then a letter (note name must be: a,b,c,d,e,f,g), then another number (common duration: .25, .5, 1, 2, 3, 4)

There is a space between two notes.

Third Step:

Click buttons

You can download your melody's audio file if you think it sounds good (chrome: click on three vertical dots). If not, click "Refresh Your Melody" button, compose again. Then you can import that audio file into music softwares (DAW) such as Steinberg Cubase, Ableton Live, Garageband, Cakewalk Sonar, FL Studio, Apple Logic Pro, Sony Acid, etc. for editing, recording, mixing and mastering the audio file.


Usually, people have to spend months or years to learn Western music theory in order to become a composer/songwriter. Because there are a lot of stuffs in Western music theory such as staff (stave), time signature, key signature, measure, vertical bar lines, bass clef, treble clef, tie, slur, dot, tuplets, etc.

Now, you just need five minutes to know 3JCN notes and rests, then you can start to write your own songs. You don't need to know Western theory to produce your songs!
