An Italian performance direction meaning "in a singing style," indicating that the performer should make the instrument sing like a human voice.
In Depth
Cantabile asks instrumentalists to emulate the most natural and expressive of all musical instruments — the human voice. This means prioritizing long, flowing melodic lines, smooth connections between notes (legato), natural phrasing with audible "breathing points," and a warm, resonant tone that projects without harshness. The melody should feel vocal even when played on an instrument incapable of producing words.
The concept of cantabile playing has been central to Western music since at least the 18th century, when Italian vocal style was considered the highest ideal for all musicians. C.P.E. Bach advised keyboard players to "sing" on their instruments, and Chopin reportedly told his piano students to attend opera performances to learn how to play cantabile. On the piano — an instrument that cannot sustain or shape a note once struck — achieving a truly cantabile effect requires extraordinary control of touch, pedaling, and the illusion of connected melodic lines.
Chopin advised his piano students to study the singing of the great soprano Giuditta Pasta, saying that the ideal of cantabile piano playing could only be learned from the human voice.
