What does a slur mean in music?

Answer 1

It depends

Verb: Speak (words) indistinctly so that the sounds run into one another.

Noun: An insinuation or allegation about someone that is likely to insult them or damage their reputation.

Answer 2

If you mean the fermata, which is an arch with a single dot under it, it means to hold for full value.

If you mean the actual dotted slur, those are staccato dots. Staccato means "detached". So with a dotted slur, you play the phrase slightly detached.

Answer 3

A slur, most commonly depicted by a curved line either above or beneath a series of notes, indicates that the music is to be played legato, or smoothly. The slur can be accompanied by the musical direction "legato" or "legatissimo", meaning, "smoothly" or "very smoothly", respectively.

Answer 4

It means for one note to flow to another; tie them together. If two notes of the same pitch are slurred, then you hold the value of the notes without making an attack at the second note.
