The curse of the ninth is a superstition connected with the history of classical music. In essence, it is the belief that a ninth symphony is destined to be a composer's last; "i.e." that the composer will be fated to die while or after writing it, or before completing a tenth. To those who give credence to the notion, a composer who produces a ninth symphony has reached a decisive landmark, and to then embark on a tenth is a challenge to fate.
