At a piano lesson, the instructor tells the student to play an E. Then the instructor tells the student to play a whole step higher. Which note should the student play next?

Answer 1

If the student starts by playing an E and then is told to play a whole step higher, they should play an F#. A whole step consists of two half steps, and moving from E to F# includes the notes E to F (one half step) and F to F# (another half step).
