Due to the nature of their craft, composers are intimately familiar with the inner workings of music. This familiarity with the core language of music allows composers to be fluent musicians and well rounded artists. In the context of piano, composers can gain the ability to improvise their own music on the spot and create their own musical vocabulary.

Being a composer means that you are not restricted by what others have written. If there is something you want to express or a piece of music you want to play in your own way, composition can enable you to do those things without having to learn the works of others: it opens up a direct dialogue with your soul.

Learning composition also means that learning an instrument is markedly more intuitive. A fledgling pianist with knowledge of theory and composition can accelerate themselves quicker than one who is primarily studying repertoire and technique. You can take the knowledge that you have and extrapolate new ideas and teach yourself about many aspects of music. A compositional approach to piano learning also allows for you to be that person at a party or a jam session who can just sit down and play along with others or even play the piano while singing yourself.
