In music performance and [[musical notation|notation]], '''legato''' ({{IPA|it|leˈɡaːto|}}; [[Italian language|Italian]] for "tied together"; French ''lié''; German ''gebunden'') indicates that musical notes are played or sung smoothly, such that the transition from note to note is made with no intervening silence. Legato technique is required for [[slur (music)|slurred]] performance, but unlike slurring (as that term is interpreted for some instruments), legato does not forbid [[articulation (music)|articulating]] the notes with a very slight interruption.

Standard notation indicates legato either with the word ''legato'', or by a slur (a curved line) under notes that form one legato group. Legato, like [[staccato]], is a kind of articulation.

There is an intermediate articulation called either ''mezzo staccato'' or ''non-legato'' (sometimes referred to as ''[[portato]]'').

==Classical string instruments==
In music for Classical [[string instrument]]s, legato is an articulation that often refers to notes played with a full [[Bow stroke|bow]], and played with the shortest silence, often barely perceptible, between notes. The player achieves this through controlled wrist movements of the bowing hand, often masked or enhanced with                                                                                                                                                  [[vibrato]]. Such a legato style of playing can also be associated with [[portamento]].

==Guitar==
In [[guitar|guitar playing]] (apart from classical guitar) legato is used interchangeably as a label for both musical articulation and a particular application of technique—playing musical phrases using the fretting hand to play the notes—using techniques such as [[glissando]], [[Finger vibrato|string bending]], [[hammer-on]]s and [[pull-off]]s instead of picking to sound the notes.  The fact that the same finger is both setting the string vibrating and setting the pitch leads to smoother transitions between notes than when one hand is used to mark pitch while the other strikes the string. Legato ''technique'' to provide legato ''articulation'' on electric guitar generally requires playing notes that are close and on the same string, following the first note with others that are played by hammer-ons and pull-offs. 

Some guitar virtuosos (notably [[Allan Holdsworth]], [[Shawn Lane]] and [[Brett Garsed]]) developed their legato technique to the extent that they could perform extremely complex passages involving any permutation of notes on a string at extreme tempos, and particularly in the case of Holdsworth, tend to eschew pull-offs entirely for what some feel is a detrimental effect on guitar tone as the string is pulled slightly sideways. The term "hammer-ons from nowhere"{{Citation needed|date=October 2012}} is commonly employed when crossing strings and relying solely on fretting hand strength to produce a note but on a plucked string. Many guitar virtuosos are well-versed in the legato technique, as it allows for rapid and "clean" runs.  Multiple hammer-ons and pull-offs together are sometimes also referred to colloquially as "rolls", a reference to the fluid sound of the technique. A rapid series of hammer-ons and pull-offs between a single pair of notes is called a [[trill (music)|trill]]. 

Legato on guitar is commonly associated with playing more notes within a beat than the stated timing, i.e., playing 5 (a [[tuplet|quintuplet]]) or 7 (a septuplet) notes against a quarter-note instead of the usual even number or triplet. This gives the passage an unusual timing and when played slowly an unusual sound. However, this is less noticeable by ear when played fast, as legato usually is. There is a fine line between legato and two-hand [[Tapping|finger tapping]], in some cases making the two techniques harder to distinguish by ear.  Generally, legato adds a more fluid, smooth sound to a passage.

==Synthesizers==
In [[synthesizer]]s legato is a type of [[monophonic (synthesizers)|monophonic]] operation. In contrast to the typical monophonic mode where every new note articulates the sound by restarting the [[ADSR envelope|envelope generator]]s, in legato mode the envelopes are not re-triggered if the new note is played "legato" (with the previous note still depressed). This causes the initial [[Transient (acoustics)|transient]] from the attack and decay phases to sound only once for an entire legato sequence of notes. Envelopes reaching the sustain stage remain there until the final note is released.

== Vocal music ==
{{see also|Melisma}}
In classical [[singing]], legato means a string of sustained vowels with minimal interruption from consonants. It is a key characteristic of the [[bel canto]] singing style that prevailed among voice teachers and singers during the 18th century and the first four decades of the 19th century.  Usually referred to as ''the line'', a good, smooth legato is still necessary for successful classical singers. In Western Classical vocal music, singers generally use it on any phrase without explicit articulation marks. Usually the most prevalent issue with vocal legato is maintaining the "line" across registers.
