Aeolian tone
From Tardis Wiki, the free Doctor Who reference
Aeolian tones were a form of music created by natural processes, such as wind. The god Maestro sought to destroy the universe so that Aeolian tones were the only type of music that existed, and altered reality beginning in 1925 to leave Earth without music. Maestro admitted their goal to the Fifteenth Doctor before he and Ruby Sunday, with some assistance from the Beatles, were able to banish them.
