A Dictionary of Music and Musicians/Sempre

SEMPRE, 'always'; a word used in conjunction with some other mark of time or expression to signify that such mark is to remain in force until a new direction appears. Its purpose is to remind the performer of the directions which might otherwise be forgotten—as in the scherzo of the Eroica Symphony, where the direction Sempre pp. e staccato is repeated again and again throughout the movement.
