There are two basic concepts that must be learned and combined to play a musical instrument, and they are the ability to read sheet music as well as the physical ability to play the instrument. Learning to read music is not always easy, but those with talent will overcome their difficulties if they practice on a regular basis. Over time, they will acquire the skill of sight reading sheets and be able to understand each note that comprises the musical score.
Learning how to master the physical concepts of playing an instrument is not a generalization as each instrument is different, so many students focus on just one. No matter what instrument they choose, they must learn all the facets of how the instrument works and adjust their manual abilities to make it function correctly. After they have mastered the basics of the instrument, they can then combine it with their knowledge of notes to create music for others to enjoy.
