Compose Music on Piano. How?

Composing music depends on a basic knowledge of musical symbols and their relative music notes. The mixture of different tunes based on this knowledge and inspiration from various melodies around you can lead to your own musical creation.

1.Decide on a few related musical chords that are in harmony to each other. This could be either in a major or a minor chord, or simply musical notes that appeal to your ear.
2.Select a melody that changes relatively to the music chords you chose. This usually applies to the right hand.
3.Add the chords to the relative music notes for the left hand. This can be found by experimenting. One method is to use chords that contain the same note played in the melody. This step is for those with more musical knowledge, but if you have an ear for music, you probably will be able to do this.

Observe the patterns of existing songs in the genre you are interested in writing in. This will enable you to examine the patterns typical of these pieces, which will help formulate your own piece.
It is also useful to play existing songs, working out its relative melody and chords. That way you can pick a starting note, and work out its relative position on the piano keyboard.
Sometimes it helps to record the music you have created in an written form. This will require knowledge of how to write the notes, or you can note it in a way you understand and find someone with the relevant music knowledge to translate it.
