Sight reading is an important skill in learning to play music you haven't seen before. When you take lessons you will learn to focus on the music page and not on the keyboard or your hands.
Tracking the notes with your eyes beyond where you are playing at the moment will help you to becoming a great music reader. After you sign up for lessons You will learn to focus on all the music elements on the page that you are playing.
The skill of reading new music by sight is the ability of a musician to play an unfamiliar work upon viewing it for the first time. This ability is expected of professional musicians and serious amateurs who play classical music and other styles.
HEAR MUSIC WITHOUT USING YOUR EARS
An even more refined skill is the ability to look at a new piece of music and hear most or all of the sounds (melodies, harmonies, timbres, etc.) in one's head without actually having to play the piece.
Do you think that Beethoven, who started going deaf early in his lifetime, could hear the music in his head when he looked at notes on staff paper? Did you know that he wrote some of his most famous pieces after he became totally deaf?
EARN MONEY AS AN ACCOMPANIST
After you learn to read the music at your lessons you might enjoy being an accompanist for choral groups and instrumental and vocal soloists. This is a good way to earn some money by using your reading skills at the piano.
PLAYING MUSIC WITH OTHERS
With the exception of solo performances, where memorization is usually expected, classical musicians ordinarily use sheet music when performing especially for chamber music when you are playing with other people at the same time.
Piano lessons will help you become proficient at sight reading by following all the visual details in the music.
