Final answer:
The first step of sight reading is identifying the key signature, as it sets the tonal framework for the pieces .option b is correct answer.
Step-by-step explanation:
The first step of sight reading is identifying the key signature. Before you dive into the rhythms and pitches of the piece you are about to play, it is important to know what sharps or flats persist throughout the composition. This knowledge will help you avoid accidental mistakes and understand the tonality of the music.
In combination with the key signature, you'll also want to identify the time signature because it tells you the rhythmic structure of every measure you will read.
Once the key and time signature are established, the sight reader may look at other elements such as rhythms and pitches, but these are secondary to understanding the framework in which those notes and rhythms exist. Therefore, the correct answer to the question "What is the first step of sight reading?" is b. identifying the key signature.
