Step 7) How to Compose your Music – Part 15
The Key & Scale should match the emotion
Choose, if not already done, the key and scale you wish to use for your song. You can use more than one scale and key in a song or piece of music if you wish.
Choose a scale you like the sound of, and feel would go well with the song you want to compose, and matches the emotion you have chosen for your song
If you need to, play or sing each note of the scale until you feel comfortable with playing or singing each note. Really become familiar with the sounds the scale makes, by varying the sequence you play the notes.
Do this until you are completely satisfied you have the right scale for your intended song.
You can do the same thing with each of the 12 keys unless you have already decided on a key for your song based on past experience.
Different keys and different scales make different combinations of sounds for you to create and experiment with. Experimenting with them will also give you more ideas for your melodies.
