A leap is one of the most difficult piano techniques, and, whenever something is challenging, a common reaction is to stop breathing and stiffen the body, including the hands and arms. However, this is the opposite of what is needed, especially in a leap where actual movement across the keyboard is involved.
What is a leap in sheet music?
In music, a step, or conjunct motion, is the difference in pitch between two consecutive notes of a musical scale. In other words, it is the interval between two consecutive scale degrees. Any larger interval is called a skip (also called a leap), or disjunct motion.
