Definition

Legato and slur are two musical terms that are often used interchangeably, but they actually have distinct meanings. Legato refers to a smooth and connected style of playing or singing, where each note flows seamlessly into the next. Slur, on the other hand, is a notation that indicates that a group of notes should be played or sung smoothly without any separation between them. In essence, legato is a performance style, while slur is a notation marking.

Notation

When it comes to notation, the main difference between legato and slur lies in their symbols. Legato is notated by a curved line that connects the notes, indicating that they should be played or sung smoothly. Slur, on the other hand, is represented by a curved line that covers a group of notes, indicating that they should be played or sung without separation. While both symbols serve to guide the performer on how to approach the music, they have slightly different implications in terms of articulation.

Articulation

One of the key distinctions between legato and slur is their impact on articulation. Legato is a performance technique that focuses on creating a smooth and connected sound, achieved by sustaining each note until the next one is played or sung. Slur, on the other hand, is a notation that indicates a group of notes should be played or sung without separation, but it does not necessarily require the same level of smoothness as legato. In this sense, legato is more about the quality of sound, while slur is more about the grouping of notes.

Execution

When it comes to executing legato and slur, performers need to pay attention to different aspects of their playing or singing. For legato, the focus is on sustaining each note and ensuring a seamless transition between them, which requires control over breath or bowing technique. Slur, on the other hand, requires performers to play or sing a group of notes without separation, but the emphasis is more on the grouping of notes rather than the smoothness of the sound. Both techniques require precision and attention to detail, but in slightly different ways.

Effect on Music

Both legato and slur have a significant impact on the overall sound and feel of the music. Legato creates a sense of continuity and flow, making the music sound more connected and expressive. Slur, on the other hand, groups notes together and can create a sense of legato even when the individual notes are not played or sung with the same level of smoothness. The use of legato and slur can greatly influence the interpretation of a piece of music and contribute to its emotional impact on the listener.

Application in Different Instruments

While both legato and slur are applicable to a wide range of musical instruments, their execution may vary depending on the instrument. For example, string players may use bowing techniques to achieve legato or slur, while wind players may focus on breath control. Pianists may use finger legato to connect notes smoothly, while vocalists may use breath support to achieve a legato line. Each instrument has its own unique challenges when it comes to executing legato and slur, but the overall goal remains the same – to create a seamless and connected sound.

Conclusion

In conclusion, while legato and slur are often used interchangeably, they have distinct meanings and implications in music. Legato is a performance style that focuses on creating a smooth and connected sound, while slur is a notation marking that indicates a group of notes should be played or sung without separation. Both techniques have a significant impact on the overall sound and feel of the music, and their execution may vary depending on the instrument. Understanding the differences between legato and slur can help performers interpret music more accurately and expressively.
